Chances are looking bright from more rainfall for Chennai this weekend. Fresh spell of rain is expected to commence over south from Friday onwards and hopefully Chennai will have better luck this time.
Tirunelveli gets battered, Rainfall in Tamil Nadu ending 8.30 am on 21.04.2015
====================================
The cyclonic circulation extending upto 0.9 km a.s.l over Comorin area and neighbourhood now lies over Lakshadweep-Maldives area. Nanguneri tops with super spell.
Meanwhile, Kalakkad gets second 100 mm rainfall of the year.
Today is World Earth Day, Take the manthra of 3R- Reduce, Reuse, Recycle, Plant and preserve trees, one of the helping factor for Rains. Protect the environment ,Let us give this precious Earth to our future generations,cleaner and greener.
Earth Day is an annual event, celebrated on April 22, on which day events worldwide are held to demonstrate support for environmental protection. It was first celebrated in 1970, and is now coordinated globally by the Earth Day Network, and celebrated in more than 192 countries each year.
In 1969 at a UNESCO Conference in San Francisco, peace activist John McConnell proposed a day to honor the Earth and the concept of peace, to first be celebrated on March 21, 1970, the first day of spring in the northern hemisphere. This day of nature’s equipoise was later sanctioned in a Proclamation written by McConnell and signed by Secretary General U Thant at the United Nations. A month later a separate Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970. Nelson was later awarded the Presidential Medal of Freedom Award in recognition of his work. While this April 22 Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations. Numerous communities celebrate Earth Week, an entire week of activities focused on environmental issues.
for every tree what is grown, corporation is destroying 3 trees. How to counter this?
Grow more and more trees… they should fedup
there is no place to grow tree all turned out to b concrete jungle…..gone r those days wer ppl grow garden n small flower trees in individual houses… each house in kerala hav a big area for trees n garden still 😦
all gardens turned into parking space now
if possible plant Punga tree,( Milletia Pinnata/ Pongamia Pinnata- Scientific name), it will give cool air, as well as which produce more Oxygen than any other trees
Typically they fall at about 7 miles per hour in still air, but this depends on the size of the drop, air movement, and other factors. The biggest drops (up to a quarter inch) can fall as fast as 18 miles per hour; faster than that, and they break up into smaller drops.
kea.metsite.com will not be working for some time. Some idiot dug up the road and all telephone lines got cut. Airtel Broadband not working due to this. Waiting for their person to fix it, lets see how quick they are.
all connections got cut, including BSNL. Moreover BSNL ppl on strike
u need fiber connection over air switch to ACT for a backup low price
that would have been destroyed to pieces too. Those ppl just destroyed everything that came on their way. Cars parked on the road where thrown into the platforms
How many trees are cut down each day?
Throughout the world, about 900 million trees are cut down annually, as of 2014. That equates to about 2.47 million trees cut down every day. These trees are used to make everything from lumber and paper to deodorant and food additives.
Wanting to know whether the link Dinamalar epaper – provided by you has any information on weather – or just you have provided a link for information purpose.. When I opened it I could see only an article on Chidambaram Temple.
that is what i have mentioned, just go through that link, it was apt news on world earth day, Chidambaram Temple Idol is situated on World Magnetic Centre. I have just provided that link, but full news given in Non-Weather Related Page.
This was published in yesterday’s Dinamalar, Indian and World Scientist have surprised. This will be the news of the day.

HEAVY T showers also expected for #chennai, S,S-E Karnataka, #Bangalore and S Andhra on evening, midnight of Friday and early hrs of 25-Apr.
RT @manoramaonline: Heavy rain in #Kerala, three die of lightning in #Thiruvananthapuram
Thiruvananthapuram: Three men died here after they were struck by lightning on Tuesday, a day that saw parts of Kerala receiving heavy rain.
The deceased have been identified as Jagan from Kunnukuzhy and Freddy and Michael, both hailing from Poovar.
Thampanoor has been inundated following heavy rain which started in the afternoon. The Thiruvananthapuram District Collector has issued a warning to the residents.
Travel to hilly regions, including Ponmudy, has been restricted. People residing at lowlands have been asked to keep a strict vigil.
The Collector ordered district, taluk and village-level officials to return to respective offices.
Heavy rain continues to lash various districts in the state.
According to MeT office, heavy rains were also reported from Alappuzha, Punalur and Kottayam areas.
An air current formed in the skies of Lakshadweep is said to be the reason for the rain. The unexpected rain caused huge traffic gridlock in Ernakulam. The Meteorological Department said that heavy to moderate rains would continue for two-three more days.
On Friday & Saturday (24 & 25-Apr) an upper-level N-S trough from E-central India to S-E Tamilnadu is expected .. http://ow.ly/i/asR2W
On Friday, the LWD is expected from S Tamilnadu to N Tamilnadu into S Andhra and to N-E Karnataka … http://ow.ly/i/asRVD
This LWD on friday is expected to push in moisture thru S-E from Bay.
The upper-level trough and LWD can pop heavy T showers for N Tamilnadu
As of latest GFS..
HEAVY widespread rain for N,central,N-coast,central-coast Tamilnadu on evening, midnight of 24-Apr http://ow.ly/i/asShP
HEAVY T showers also expected for #chennai, S,S-E Karnataka, #Bangalore and S Andhra on evening, midnight of Friday and early hrs of 25-Apr.
we have a chance until 26th, leave the intensity, it may vary from time to time, but precipitation confirmed till 26th.
okok….
BTWameen exams over?..
yes…. holidays started yesterday
infact last time there was no intensity prediction right…people were only hoping for 2-3 cms back…so this time there is a possibility of a intense shower…
24th over North Tamilnadu.
This forecast shows that 500 HPA level contour at 582, that means the convection is available for precipitation.
Anything lesser than 584 is good for precipitation.
The upper air cyclonic circulation over Lakshadweep area and neighbourhood persists and now extends upto 3.1 km above
mean sea level. A low pressure area may form over the region during next 24 hours. Imd Delhi Midday report
Below normal rainfall predicted for 2015 S.W.M by IMd intial report, 93% of Normal rainfall predicted, Sky met stands in its report of Normal rain fall
The rains will be 93% of the 50-year average. Probability of deficient monsoon is 33%, probability of normal monsoon is 28% and the probability of above normal monsoon is negligible. Imd monsoon forecast
as i have been forecasting, the same IMD has come out with.
but we still have the hope with IOD, if it turns positive before july 15th, SWM shall become normal.
Its bad luck in the absence of WD, the present CC moving away from Indian peninsula. Our next hope will be at SE-BOB. Lets shift the focus on cloud build up over that area.
I was confused about its unfolding (may not be that much active TS activity as we expected earlier).
Actually the present LPA lacks WD’s support to get some elevation towards peninsular India. So this LPA is going in regular NW-direction instead of N/NE
Answer ti my question above
answered
Summer gripping Telangana and Rayalaseema
Temperatures at 3 pm
Singareni manuguru coal belt 44.9 degrees
Medak 42.9
kadapa 42.6
Anantapur 42
kurnool 41.4
Hyderabad shamshaabad airport 40
The outer bands of LPA/trough of LPA pumping moisture into Kerala, Karnataka and interior Telangana. This moisture pumping may ignite local convective TS activity in those areas.
present LPA (already entered Arabian ocean) may not ignite anything over Chennai. So we need to shift our focus on SE-BOB’s fresh convection.
what happened to N TO S trough which was about to bring rains to chennai
partha answered ur question above.
so… trough will form on 26th… so rains for chennai on 26th?
need to see how it will unfold…..
Why the 24th rainfall quantum reduced by GFS, the trough formation is getting delayed.
The Inverted trough expected on 24th is going to form only on 26th as per GFS.
MJO and trade winds weakened. and there is no WD too for the necessary moisture. so no major things will happen during next 2-3 days except some isolated convectional TS activity over Kerala, TN, isolated places of Karnataka, Telangana & AP states.
High Intensity Rains lash Trivandrum and Kerala, ending 8.30 am on 22.04.2015

Ya 🙂 btw KSNDMC has added arnd 50 new RGs in bangalore..
50!!??..wow
Do you have list of the 50?
Hmm no, but its easy to find out…. Just go to the weather info page of KSNDMC site and get the list of stations taluk-wise for bangalore urban district. The last few RGs under each of the taluks – bangalore north, south, east and anekal are the new ones…. Many of the new RGs in bangalore north have got 50mm+ today apart from Rajanakunte….
Yeah I checked. Banaswadi 5.5mm!!! Not much here though. Maybe I was wrong about its location all along. Not able to find Beniganahalli data
Crisil worries on weak monsoon prediction
——————————–
The bleak monsoon forecast by the Indian Meteorological Department has the potential to shave off 0.5 per cent of the GDP forecast of 7.9 per cent of fiscal 2016, said Crisil in a report.
A second straight year of weak monsoon will decrease the efficacy of irrigation ecosystem and hit agricultural output and farmers adversely. In addition, unseasonal rains since early March have already had a negative impact on many crops, it added.
Given weak investment climate, tepid export growth and fragile consumption, a normal monsoon is crucial to push economic growth this year, it said.
Without predicting the effect of El Niño, IMD on Wednesday said the monsoon to be at 93 per cent of the long period average with a margin of error of five per cent on either side.
If El Niño indeed plays out, it will be for the second straight year. It impacts spatial distribution of rainfall, causing floods in some parts and drought in others. And this time, the impact on agricultural output will be greater compared with last year, said Crisil. http://www.thehindubusinessline.com/industry-and-economy/agri-biz/crisil-worries-on-weak-monsoon-prediction/article7130589.ece
“Our base case, given a normal monsoon, is that agricultural growth will be 3% — up from a weak base of 1.1% in fiscal 2015,” it said.
models are always like that…dont worry some activity is there..last week spell was also like this. so models have promised much lets see…i am sure we will get atleast 4 cms.. Meenambakkam 105 mm last week rain anything to add will be real bonus
IMD predicts second consecutive sub-normal monsoon
——————————————————————–
The India Meteorological Department’s (IMD) first outlook for this year’s southwest monsoon (June -September) released here on Wednesday raised the prospect of a second-straight sub-normal monsoon which could impact agricultural output.
The Met department predicted that rainfall could be 93 per cent (subject to an error margin of plus/minus 5 per cent) of the Long Period Average (LPA). It classifies rainfall between 96 and 104 per cent of the 50-year average of 89 cm. as normal.
Actual rainfall last year was 88 per cent of the LPA, the lowest in almost 30 years. The four-month-long monsoon accounts for 70 to 75 per cent of the country’s annual rainfall.
Under the five category probability forecast, which indicates the chances of good or poor rainfall, the IMD has predicted that there is a 28 per cent probability of normal rainfall while there is a 68 per cent of a poor spell (33 per cent probability of deficient rainfall and 35 per cent chances of below normal rain).
“The onset of the southwest monsoon will be announced on May 15, we will have a clearer idea of distribution in time for the June forecast,” said LS Rathore, Director General of Meteorology, IMD.
Parts of northwest and central India are likely to be affected by the shortfall in seasonal rain.
El Nino concern
The El Nino condition is caused by prolonged warming of equatorial Pacific Ocean surface waters and occurs at irregular intervals of two to seven years. In India, it had affected rainfall patterns and caused two severe monsoon failures in 2002 and 2009.
“El Nino has been factored into this forecast but there are other parameters. Of the 14 years in the past when we had El Nino, eight years had bad monsoons,” said Rathore.
Several international Met agencies have forecast a 70 per cent probability of an El Nino event in 2015. Harsh Vardhan, the Earth Sciences Minister, said that conditions were being monitored while “the Prime Minister’s Office and Cabinet Secretariat have also been informed to be prepared”.
“Currently, weak El Nino conditions are prevailing over the Pacific. The latest forecast from the IMD-IITM coupled model forecast indicates El Nino conditions are likely to persist during the southwest monsoon season,” the IMD noted in a statement.
Worrisome picture
Analysts expressed concerns about the possibility of a poor monsoon on crop production and the wider economy particularly since it will come in the aftermath of unseasonal rainfall and hailstorms between end-February and early-April.
The western disturbances, which Rathore said will not have a bearing on the southwest monsoon, caused significant damage to key Rabi season crops like wheat and mustard as also vegetables and fruits over some 10 million hectares across north, west and central India.
“Unseasonal rains since early March have already had a negative impact…a deficient monsoon, if it comes true, will shave 50 basis points (0.5 per cent) from our GDP forecast of 7.9 per cent,” stated a Crisil research report.
One truth about the Numerical Weather Prediction(NWP) models i.e., almost all our models that we see in day to day output has the greatest difficulties while inputting certain parameters. Tropical Convection is one among those parameters. The way the atmospheric flow changes would take place can nowadays be predicted with decent accuracy , but the time, location and intensity predictions of Tropical convection remains one tough stuff to deal with ……..
After a break Karnataka joins the party, Rainfall ending 8.30 am on 22.04.2015
=============================================
The cyclonic circulation over Lakshadweep-Maldives area now lies over Lakshadweep and neighbourhood and extends upto 3.1 kms a.s.l. A Low pressure area may form over the same region during next 24 hours. Over 200 stations have reported rainfall, hence cut-off is kept at 35 mm.
Good morning pj sir…. i’m eagerly waiting for rains….. can i expect atleast 50mm in my area… north chennai… and will the coming spell will be widespread?
Flash news IMD expecting 93% of long term average this season.
33% probability for deficit monsoon
28% probability for normal monsoon
Negligible probability for excess monsoon.
GM Guys…Nice topic…rains due to a minor favorable circulation in TN?
position of low is very critical of chennai rain…this time on GOM
Today we may expect thunder storm activity in Krishnagiri dharmapuri belt

Heat is building up steadily…dont get ur expctations high for the weekend rains…
There is a long harsh summer coming up may -july….
Thinking abt a false ceiling for my house…how abt a false ceiling for chennai? Is it possible
False ceiling with AC for whole city….©=©
if, each and every house grow 1 tree, then we don’t require False Ceiling for Chennai
for every tree what is grown, corporation is destroying 3 trees. How to counter this?
Grow more and more trees… they should fedup
there is no place to grow tree all turned out to b concrete jungle…..gone r those days wer ppl grow garden n small flower trees in individual houses… each house in kerala hav a big area for trees n garden still 😦
all gardens turned into parking space now
if possible plant Punga tree,( Milletia Pinnata/ Pongamia Pinnata- Scientific name), it will give cool air, as well as which produce more Oxygen than any other trees
Wat is the temp of a rain drop whn it hits the ground? Same as cloud temp?
Typically they fall at about 7 miles per hour in still air, but this depends on the size of the drop, air movement, and other factors. The biggest drops (up to a quarter inch) can fall as fast as 18 miles per hour; faster than that, and they break up into smaller drops.

as i have been forecasting, the same IMD has come out with.
but we still have the hope with IOD, if it turns positive before july 15th, SWM shall become normal.
The moisture spewed by the outgoing low is descending in the south in.Kar And north in.Tn causing thunder cell activities

who knows wer 400 cr goes ! melairukravanukku than theriyum 😛
hope at least our next generation get reliable and to the core forecasts, instead of stereotype reports
Latest GFS update, further reduction in precipitation.
y are they doing like this…., as usual
as expected ameen….
latest gfs reduced rains but decent ones by sun.. high getting in d way

Its bad luck in the absence of WD, the present CC moving away from Indian peninsula. Our next hope will be at SE-BOB. Lets shift the focus on cloud build up over that area.
how about this spell from 23-27 your take on that?
I was confused about its unfolding (may not be that much active TS activity as we expected earlier).
Actually the present LPA lacks WD’s support to get some elevation towards peninsular India. So this LPA is going in regular NW-direction instead of N/NE
Answer ti my question above
answered
Summer gripping Telangana and Rayalaseema
Temperatures at 3 pm
Singareni manuguru coal belt 44.9 degrees
Medak 42.9
kadapa 42.6
Anantapur 42
kurnool 41.4
Hyderabad shamshaabad airport 40
The circulation near ker coast Is now a invest area
9.6n 70.8e intensty 15 knots
At the same time heavy rains in visakhapatnam and district
Started Raining with thunders in hyderabad also
The outer bands of LPA/trough of LPA pumping moisture into Kerala, Karnataka and interior Telangana. This moisture pumping may ignite local convective TS activity in those areas.
what’s your take on up coming spell for chennai? 24-27
present LPA (already entered Arabian ocean) may not ignite anything over Chennai. So we need to shift our focus on SE-BOB’s fresh convection.
what happened to N TO S trough which was about to bring rains to chennai
partha answered ur question above.
so… trough will form on 26th… so rains for chennai on 26th?
need to see how it will unfold…..
Why the 24th rainfall quantum reduced by GFS, the trough formation is getting delayed.
The Inverted trough expected on 24th is going to form only on 26th as per GFS.
http://moe.met.fsu.edu/cyclonephase/gfs/fcst/archive/15042200/108.html
so we will receive heavy rains on 26th?
MJO and trade winds weakened. and there is no WD too for the necessary moisture. so no major things will happen during next 2-3 days except some isolated convectional TS activity over Kerala, TN, isolated places of Karnataka, Telangana & AP states.
good
????.
not going to make much difference , all models are on target..so expect 120-140mm from friday-sunday..
Yes already a big cloud mass is began its journey from Indonesia towards chennai…
Excellent rains around Bangalore… But still nothing is there for Bangalore… Thanks to the out moving low near lakshdweep..
Yes..massive clouds over entire northern horizon..but don’t know whether it s coming our way..
looks to be targeting same places like yday (rajanakunte etc)
Ya :(… angry
Just thunders for long. No rains yet
😦
what are the chances for tonight match to happen
Same here..heavy lightning flashes towards north n rumbling thunders
Strong winds here. Think it is raining slightly to north of here
Storm has got struck north of us..Not moving at all..
Storm peaked too early for Blore liking..so it might weaken a lot n reach us I guess..let’s see
Might be raining in yelahanka side??
Yes surely
any rain in chinnaswamy
No..Not yet
any chances tonight
If Storm moves little south (With good intensity)… Match is gone..
i dont kno y everyone is so obsessed wit nos.. every mm we recive this mnth is a bonus
on friday,sunday
next two day south krntk and krla, will receive heavy showers..

Gud rainfall yesterday night in outskirts. City missed the spell.
heavy lighting activity in Bangalore central and north
As expected storm has weakened a lot and reached my place.. drizzling with heavy lightning overhead.. can’t expect more than drizzles and light rain..
Roads were completely dry just half a km to the east of my house.. its drizzling anyway nw..
Just 2mm recorded by my RG in sahakarnagar north bangalore.. GKVK, vidyaranyapura and yelahanka have got much more..
Heavy TS in Karnataka. IMD forecasts increase in rainfall from tomorrow in south India.

Wow !!!!…great start to the new rg there 🙂
Ya 🙂 btw KSNDMC has added arnd 50 new RGs in bangalore..
50!!??..wow
Do you have list of the 50?
Hmm no, but its easy to find out…. Just go to the weather info page of KSNDMC site and get the list of stations taluk-wise for bangalore urban district. The last few RGs under each of the taluks – bangalore north, south, east and anekal are the new ones…. Many of the new RGs in bangalore north have got 50mm+ today apart from Rajanakunte….
Yeah I checked. Banaswadi 5.5mm!!! Not much here though. Maybe I was wrong about its location all along. Not able to find Beniganahalli data
Crisil worries on weak monsoon prediction
——————————–
The bleak monsoon forecast by the Indian Meteorological Department has the potential to shave off 0.5 per cent of the GDP forecast of 7.9 per cent of fiscal 2016, said Crisil in a report.
A second straight year of weak monsoon will decrease the efficacy of irrigation ecosystem and hit agricultural output and farmers adversely. In addition, unseasonal rains since early March have already had a negative impact on many crops, it added.
Given weak investment climate, tepid export growth and fragile consumption, a normal monsoon is crucial to push economic growth this year, it said.
Without predicting the effect of El Niño, IMD on Wednesday said the monsoon to be at 93 per cent of the long period average with a margin of error of five per cent on either side.
If El Niño indeed plays out, it will be for the second straight year. It impacts spatial distribution of rainfall, causing floods in some parts and drought in others. And this time, the impact on agricultural output will be greater compared with last year, said Crisil.
http://www.thehindubusinessline.com/industry-and-economy/agri-biz/crisil-worries-on-weak-monsoon-prediction/article7130589.ece
“Our base case, given a normal monsoon, is that agricultural growth will be 3% — up from a weak base of 1.1% in fiscal 2015,” it said.

What to do it is GFS ….
It’s not GTS to be perfect 🙂
yes!
Rain chance for chennai is reducing day by day as models are not consistent in their forecast
Not reducing really confirm rains this weekend
models are always like that…dont worry some activity is there..last week spell was also like this. so models have promised much lets see…i am sure we will get atleast 4 cms.. Meenambakkam 105 mm last week rain anything to add will be real bonus
Don’t depend on models.
IMD predicts second consecutive sub-normal monsoon
——————————————————————–
The India Meteorological Department’s (IMD) first outlook for this year’s southwest monsoon (June -September) released here on Wednesday raised the prospect of a second-straight sub-normal monsoon which could impact agricultural output.
The Met department predicted that rainfall could be 93 per cent (subject to an error margin of plus/minus 5 per cent) of the Long Period Average (LPA). It classifies rainfall between 96 and 104 per cent of the 50-year average of 89 cm. as normal.
Actual rainfall last year was 88 per cent of the LPA, the lowest in almost 30 years. The four-month-long monsoon accounts for 70 to 75 per cent of the country’s annual rainfall.
Under the five category probability forecast, which indicates the chances of good or poor rainfall, the IMD has predicted that there is a 28 per cent probability of normal rainfall while there is a 68 per cent of a poor spell (33 per cent probability of deficient rainfall and 35 per cent chances of below normal rain).
“The onset of the southwest monsoon will be announced on May 15, we will have a clearer idea of distribution in time for the June forecast,” said LS Rathore, Director General of Meteorology, IMD.
Parts of northwest and central India are likely to be affected by the shortfall in seasonal rain.
El Nino concern
The El Nino condition is caused by prolonged warming of equatorial Pacific Ocean surface waters and occurs at irregular intervals of two to seven years. In India, it had affected rainfall patterns and caused two severe monsoon failures in 2002 and 2009.
“El Nino has been factored into this forecast but there are other parameters. Of the 14 years in the past when we had El Nino, eight years had bad monsoons,” said Rathore.
Several international Met agencies have forecast a 70 per cent probability of an El Nino event in 2015. Harsh Vardhan, the Earth Sciences Minister, said that conditions were being monitored while “the Prime Minister’s Office and Cabinet Secretariat have also been informed to be prepared”.
“Currently, weak El Nino conditions are prevailing over the Pacific. The latest forecast from the IMD-IITM coupled model forecast indicates El Nino conditions are likely to persist during the southwest monsoon season,” the IMD noted in a statement.
Worrisome picture
Analysts expressed concerns about the possibility of a poor monsoon on crop production and the wider economy particularly since it will come in the aftermath of unseasonal rainfall and hailstorms between end-February and early-April.
The western disturbances, which Rathore said will not have a bearing on the southwest monsoon, caused significant damage to key Rabi season crops like wheat and mustard as also vegetables and fruits over some 10 million hectares across north, west and central India.
“Unseasonal rains since early March have already had a negative impact…a deficient monsoon, if it comes true, will shave 50 basis points (0.5 per cent) from our GDP forecast of 7.9 per cent,” stated a Crisil research report.
Given a normal monsoon, agricultural growth should touch 3 per cent, up from 1.1 per cent in 2014-15.http://www.thehindubusinessline.com/industry-and-economy/agri-biz/imd-forecasts-below-normal-monsoon-rains-this-year/article7129984.ece?homepage=true
As we near the weekend, rains r getting less…
One truth about the Numerical Weather Prediction(NWP) models i.e., almost all our models that we see in day to day output has the greatest difficulties while inputting certain parameters. Tropical Convection is one among those parameters. The way the atmospheric flow changes would take place can nowadays be predicted with decent accuracy , but the time, location and intensity predictions of Tropical convection remains one tough stuff to deal with ……..
We need atleast 50mm this wknd to help us face the summer
we would get more than that this weekend rainman.
Confident as alwys…
By mistake deleted, how to undelete a post?
Press edit….delete…..then press edit and save button
Rain chance still bright
Infact foreca has removed the rains ..just 2mm now on Sat
Unbelievable first time a positive posting from you. We need to worry now!! – on the chances
