The Low pressure areas over the Arabian Sea and the Bay of Bengal continues to persist. Meanwhile, conditions continue to be favorable for the onset of North East Monsoon rains over the southern peninsular region around the 28th of October. Under the influence of the Low Pressure system in the Bay, parts of Tamil Nadu and adjoining regions will experience rains. Fishermen are advised not to venture into sea along coastal TN and Lakshadweep owing to rough seas and bad weather in deep sea areas.The extreme north of India will see rains/snow associated with an active Western Disturbance in the region.
Chennai will remain mostly cloudy with rains occasionally at isolated parts of the city. Maximum will stay close to 32 C. Humid conditions will persist.
Coimbatore could remain partly cloudy with a day time high hovering around 32 C
Madurai will see cloudy skies with day time maximum settling in the low to mid thirties. Isolated pockets can see some rainfall activity.
Vellore will stay pleasant with partly cloudy skies with a day time max. inching to 32 C
Trichy to remain partly cloudy with a chance of few isolated showers. Maximum temperature will stay around 33 C
Radar not working
Just started working… South of Chenglepet getting ready for rains… We may have to wait a little longer.
Many more happy returns of the day Gaje. Wish you good luck 🎂🎉🎊🎈🎁
Happy Birthday Gajendrakumar!
There is a rumour spreading like wildfire in whatsapp regarding unprecedented rains for chennai starting tomorrow. There is no truth whatsoever in that message. Please disregard.
Much cooler today
that’s because u r hardly awake at this time of the day
Because, its full moon day today
So u can’t sleep during full moon
Not like that…will wake up early
Diwali system
We can pull that one here…wait n see
Busvanam!
Happy birthday Gajendaran. Hope common sense prevails and all wish him in blog birthday page rather than whatsapp group, where he is not even a member.
Please add me also in whts app sir
Oh great. You can email me your number. But before that think again. It is one of the most active whatsapp groups in the world. Daily around 3,000 messages will be there easily.
I love to know abt weather and I don’t think it shd be a problem to me.
Then you can send email to keaweather@gmail.com
Thk u so much sir
Sir can I know the email id
Really too active I was in wap and came out being overwhelmed by the messages
Happy Birthday Mr. gaje….
For once Foreca is more positive than Cola
gud morning blogers 😉 i think today is the last day before NEM feeling vry exited 😉
happy birthday gaje 😉
The radar is stuck again!
Working for me
Not updating past 23.40
Updated 00:20
Only close range!
No long range also
Not for me!
What about medium and very long range?
Some interesting pop ups in sea . Very eager to watch
Good luck…
How is the weather in Pondy?
Sunny
Lol, should be a typical NEM day!
Best of luck Kea.. forecasting NEM is a real challenge. It is not done until we count the last cm of the 30 cms anticipated.
There is all of November to count.
You forgot December and january
Yes:-), every cm could be the last cm of the NEM. Such are the vagaries unless we talk about easterlies.
Thank you. Hopefully we have learnt from the earlier mistakes.
Already got Rumours by whats App. Shame on people
who created this rumour??
It was by Mr.Kannan, health dept of chennai corporation. When reporters asked this question about quantum, he directed his fingers towards IMD.
oh..no..I am wondering how models are quantifying rainfalls 😦 😦
happy birthday sor!
sir!
No idea but got tweet from our blog that it is on
ha..ha..it looks Arabian system losing convection with forward movement in MJO towards phase 3. I wonder if this Arabian system intensifies to a major system as per most of the models’ predictions (including as per few of our friends’ : ) 🙂
With this rapid turnout of event in MJO’s forward movement towards phase 3, focus will slowly turn to our BOB-system. So expecting more strengthening of 93B and hence in elevation in latitude towards CTN-NTN/SAP in today’s models’ runs when compared to yesterday. So keep fingers crossed in 🙂

Good morning friends 😁
Things are changing very positive for Tamilnadu in coming days . Most of the models looks good. This picture shows heavy rain possible along North coastal tamilnadu to Orissa coast . Rain should starts by this evening / tomorrow morning for sure . Already a a weak band seen in radar . Its was good sign.
Refresh for image*
how many times they changed this picture 😦 ???
No worries Dr.Rsrao . Finally it will show flooding rains for Tamilnadu
thank God you used “flooding” in stead of quantum of rains 🙂
Nature learnt the lesson 😂
Flooding in CHENNAI can happen even with 50 mm
Research report
Abstract
The role of the El Niño–Southern Oscillation (ENSO) on the modulation of tropical cyclone activity over the Bay of Bengal (BoB) for the 1979–2011 period is examined. It is shown that Niño-3.4 sea surface temperature (SST) anomalies are negatively correlated with the BoB tropical cyclone activity to a statistically significant percentage by a lead time of 5 months. Composites of 10-m zonal winds exhibit greater variance during La Niña events, favoring the development of low-level cyclonic vorticity. Low vertical wind shear over the central and northern BoB also aids in the development of tropical cyclones during La Niña events. Increased relative humidity is the result of enhanced moisture transport and higher precipitable water under La Niña conditions. Furthermore, storm-relative composites of relative humidity show stronger moisture pulses over the BoB during La Niña. The enhanced moisture associated with tropical cyclogenesis likely aids in the development and strengthening of the systems. ENSO forces modulations in oceanic conditions as well. The observed negative (positive) SST anomalies during La Niña (El Niño) could be seen as the result of increased (decreased) net heat flux across the sea surface. Tropical cyclone activity varies between El Niño and La Niña as a result of anomalous wind and moisture patterns during each ENSO phase.
@Pradeep John to TOI on NEM today
————————-
FORECAST FOR THE WEEK – Monsoon clouds on the horizon, light rains today
While heavy rain will be fairly widespread across coastal Tamil Nadu, it will be scattered in the interiors. “Irrespective of the low pressure near Sri Lanka and in the Arabian Sea, the monsoon will set in,“ says weather blogger Pradeep John.
“The rainfall this time will be above average,“ says Pradeep. “The deficit will be made up for in November.“

Congratulations pj …happy for you
tks narayanan.
Tks sir again.
Congrats PJ.
Happy Birthday Gaje Uncle!
Congratulations Pradeep Anna!
Thank you.
When will rain start??
cloudy morning now!
Strong Bands Visible in Radar !!!
It will move towards us , I think 😂
Yes Winds also From NE.
Yes..afternoon it will reach!
And same type of NEM rains expected like last yeat
Happy birthday gaje sir!
Congratulations PJ sir!
thank you
Heavy / Moderate rain for N,central coast #Tamilnadu , #Chennai , and S-coast #Andhra from noon/ evening of 27-Oct
#IWM
Happy birthday gaje .. As usual congrats pj
thank you.
When will the rain start ??😬😬
Chennai to taste 1st spell of rains today – Time to take ur umbrella
======================
Past few days chennai is getting some light rains, from today, its going to be different monsoon time. After 10 long months of wait, Chennai will get 1st taste of precious NEM today even though monsoon is going to set in a day later. Be prepared. Rains will start only in night. Nothing to worry in the day as you all aware, most of the NEM rains start at night and ends in morning.
Further, there is rumor in whatsapp about a message from DC, Health, Chennai Corporation about massive rains. Please ignore it. There will be rains no doubt about it. We cannnot predict 300 mm rainfall like this. It is always wise the model runs are interpreted by experienced hands.
Belated B,day wishes – Sriram and Drill Gaje Many many happy returns of the day.
Model consensus on track was posted yesterday night. Please see it in yesterday post. All models now agree on track. Nomore NE curve all positive for TN.
OMG ECMWF PREDICTS TN LANDFALL
see yesterday page.
no NE curve.
What would be there to landfall?
Due to presence of a Low Pressure system in AS, the current BOB system would take time to get strengthened. As of now the movement is very slow; slower than what was predicted.
OMG WD is almost dead look at sat image. One of the main reasons why ECMWF has removed NE recurve. But trough still seen extended N
It’s now well marked only in the mid/upper level
Happy birthdayday Mr.Gaje
Congrats Mr.PJ
Happy birthday Gaje!
Pleasant morning. Will this turn out to be the beginning of NEM
Interesting rainfall fluctuations. In 2009 Oct we got only 72mm rain , whereas the highest in recent years was in 2005 Oct with 1078 mm.
Will this year be a repeat of last year. Starting off good and disappointing thereafter…. Experienced weather trackers plz give your thoughts
Dude truly..no one knows for sure. General expectation is it will be normal NEM this time
Last year it was on time. This year slight delay. Like this there would be differences.
Hope for the best from weather God. Hope he gives rains in the form of low pressure mark and not as cyclone
Good Morning all.
A warm sunshine greets oneself in Thanjavur today after a muggy hazy weather for last two days. Forecast looks positive for rains starting by noon.
The part of the easterly wave marked in red last night has moved west quickly, seems heavier and more consistent showers can begin tonight/ tomorrow morning with very high probability !
Holiday on cards 😁
This looks GOOD!!!!
I hope your special day will bring you lots of happiness, love and fun. You deserve them a lot. Enjoy!

Moving north!
Happy b’day gaje…
Convection around the system!
Good Morning All,
Uncomfortable morning, very humid, this is the indication of rain nearing.
NEM onset around us, yippeeeeee…..
!!!!!!!!!
Drenched in yesterday’s rain and suffering from fever again. Took leave. I have very low immunity :((((
That 30 CM rainfall has been ruled out by IMD, they said we can expect heavy rainfall from tomorrow, the amount is not declared by IMD.
Today Dinamalar.
Happy birthday Gaje sir !!!!!
Congrats PJ Sir!
Vizag —– heavy rainfall to occur over south ap and costal tn….some places might recieve very heavy rainfall in these region
By vizag met department????
Yes
Wowoow!!!
Get ready……………
Happy birthday Mr.Gajendran
May god bless you.
Very humid today.waiting for rains patiently.
Rain will commence from today afternoon or evening….
Already very severe popups 200km NE,ENE ,ESE of Chennai
Wish You Many More Happy Returns of the day Lord Gaje.
Happy Birthday
Happy Birthday MR.Gajendran
Happy birthday Gajendran Sir
OMG,
Sea breeze front visible over East, surface level wind from West.
What that indicates??
Rain
I dont know, it is temporary change, will change again to NE by noon.
93B, Good improvement seen with decent convection around the the center..
Mattakalappu 92mm 3 day total 408mm
conditions r favourable for low do develop into depression in 24hrs. to 48 hrs
Congrats PJ.
you have featured in http://timesofindia.indiatimes.com/city/chennai/Monsoon-clouds-on-the-horizon-light-rains-today-in-Chennai/articleshow/49546628.cms.
Rameswaram is cloudy now with low clouds.. Rain bands swept through entire night with mild showers on n off
Foreca expects massive rains from tonight for the next 4 days and interesting look at the wind speed!
Close to 36km/hr on Friday/Saturday which is really interesting!
Just cant wait 😀
Pls put metro gram here
Metogram*
Forecas?
Yaya
Short range
.we have to believe this
Intense pop-ups seen moving to coast!
Very heavy rains possible if it maintains its intensity.
93B has shown some intensification.
Looks well organized also.
It has moved North for the past 6 hours!
http://earth.nullschool.net/#current/wind/isobaric/850hPa/orthographic=-273.54,13.55,1107
circulation looks very good now
GT recorded 14mm yesterday. 10mm from morning very heavy spell. And 4mm from eve heavy spell
How much for the month so far? Meanwhile I’m waiting for the day when Adyar will cross 100 mm for the month
http://www.foreca.com/meteogram.php?loc_id=101264527&mglang=en&units=metric&tf=12h
Tks! Wow deluge
40 mins before,strong convection seen around the llc
Will it move towards NW?
Yes
yeah..it is likely to move N-NW for next 2 days
The route which I expect.
hmm..no consensus thereafter ..i mean after nearing tn coast. upcoming run is the most expected one
NE curve likely after Nellore?
tiny confusion.recent ecmwf run extended the ridge west surprisingly that forced the system to move inland over tn.. so one or two more runs could help us to get a clear pic
So it is very tough to predict NEM system even before few days. Since lot of factors affect the NEM.
Yes , so many instances bring about instantaneous changes.
Who will lead today’s gfs commentary
Accoring to many forecast models,
Squall winds and heavy rains will be from 30th continuing into 31st/1st.
From tonight on and off heavy shwers going to start.
Oct27th a memorable date to be remembered for chennai especially.
exactly 10 years before we know what happened.
Rest is history.
Hope we get good rains this NEM though not like a repeat of 2005.
GFS run started…
Happy birthday gajendran..
First time in my life i am seeing that TS chasing Sea Breeze Front..
How it’s possible?? Indication of good rains?
Northeast Monsoon to Lash State Tomorrow
According to the Met Department, two low pressure systems exist at present – one over the Arabian Sea, west of Lakshadweep, and the other near the Sri Lanka coast. “The low pressure near the Sri Lanka coast is expected to move towards coastal Tamil Nadu and then strengthen. Under its influence, we can expect northeast monsoon to set in over coastal Andhra Pradesh, Tamil Nadu and almost simultaneously over Kerala,” Santosh said.

Wish you many happy returns of the day Mr.Gaje
Wish you many many happy returns of the day brother GAJE.
What’s situation now in.ongole?
bright sunshine
Yes in nellore too
Congrats P.J for T.O.I article
Low level convergence taking place offshore TN coast with sufficient upper level divergence aloft and behind the area at upper levels.
Implications?
Zone of enhanced vertical ascent , clouds can develop and move in slowly towards TN coast.
::::D
Thanks.
Many more happy returns of the day Gajendran sir
Congrats PJ
thank you
Happy birthday Lord Gaje! 🙂
GFS run started
Positive vorticity seems to be spreaded and enhanced across a larger area offshore TN coast.
What that implies
Conditions are favorable for clouds to form all along the region and can move towards TN coast gradually.
Thank u gts
Welcome…:)
i think AS system wont get strengthen as expected by the models but our BoB sys will develop more
maybe wind shear increase is a temporary one..they may bounce back
I thought the conditions were very conducive
last night shear increased a bit as expected by agencies
Cumulus clouds have started to form here in Thanjavur!!
Any pics from Tanjore?
Posted in WAP. I am connecting via mobile. Low connectivity, so couldn’t upload here!
moving slowly to NW
Very slow moving system
So slow moving system give lot of rains???
Yes.. But not in all cases
8.30am visible shot
bay is getting very active
seems it used few chances last night
I can see over shooting tops in arbsea system
As of now,it’s bright and sunny and no rain clouds is seen anywhere Clear skies
Convergence shown in Yellow Box, this system has pull effect from West Central Bay to its position, hence the surface and lower level wind over TN coast and West Central and SW Bay is from NNW to SSE direction.
Also i have shown in pic that RED circle which Associated Cyclonic Circulation extended to mid level, which is stronger now than yesterday.
Convectivity will increase along the coast today as the day progresses.
Also shear is very low at around 20 knots max and 10 knots around the system.
pls look at AS sys not getting stronger still as a DD
Our system entering gom
i expect some north movement as AS system not stregthen
its should cross above 10 lat
If AS system does not strengthen, then Bay Low might enter GOM through south of lanka, it might reduce the rainfall intensity over TN, hence pray for AS system to be stronger…
Hmmm. Arab system will be strong as MJO fueling it
Happy bday gaje
Hpy b day gaje
OMG its Happy B’day Gaje.
S updated
In a today’s Tamil daily daily that Chennai will be flooded on 28th how irresponsible the media persons are turning
BBC on Wednesday and Thurday night
Our system close to nagai
It’s same lpa
