UAC over west central Bay of Bengal likely to come towards chennai on monday evening.
Current synoptic factors that are favouring UAC .
1.As expected Madden Julian oscillation (MJO) has entered in Indian ocean @phase 2 with good amplitude. MJO is helping UAC by supplying moisture and more convective activity.
2.Southern oscillation index (SOI) has stabled and likely to increase in coming days. It is good for UAC..
3.UAC will be driven to Tamil nadu coast by mid level winds
4.vorticity has deepened @500,700hpa levels.
Due to UAC Andhra Pradesh has got good rains.
Rainfall impact in chennai and North tamil nadu.
Good rains would occur in chennai and NTN.
MJO @phase 2 results in good rains over NTN and SAP.
Yesterday some parts of chennai received rainfall due to UAC near Andhra was pumping good moisture over TN.
Good moisture available @500,700hpa levels.
Steering winds will be favorable for chennai to get heavy rains.
Nunga has missed rainfall from last 2 UAC’s. Hope Nunga shouldn’t miss rainfall from this UAC and it should get good rains.
Models are indicating that Low pressure over Arabian sea may strengthen into cyclone in coming days. Lets see.
southwest monsoon has set in over Kerala on 5th June 2015.it will continue to progress towards whole India in coming days.
Overall chennai has excellent chances for rainfall.

Good luck today
Hello
Hi
Rsrao sir losing of convection and gaining of convection is a part of a system. So no worries. Old convection lost new fresh will develop for chennai 😀
hope so 🙂
Yes.
ameen, why the convection lost around BOB-UAC :(???
500,700,850mb vorticity further deepened and marching towards TN coast.
Qnd latest mid level steering winds are favouring UAC to move towards tamil nadu coast
Ammen. Nice topic. U have improved so much in an year. Keep it up.
Wow, what a topic
Yes. For his sake, rains has to show up for chennai.
I too feel rains can’t miss chennai this time, let’s see
Dark clouds moving fast as result of UAC ❔❔
ameen, still why the convection not building up?

Many More Happy Returns of the Day
Happy Birthday
Thank u sir
Cyclone Deepak, Many Many Happy Returns of the Day. Have a great year ahead 🙂
Happy Birthday deepak!
Thank u
Happy Birthday Deepu.
Thank u sir.
Rsrao sir! Flash news! Convection started to rebuild!
Latest sat img!!
Due to Arabian sea circulation advancent of monsoons hepked….but Kerala missed the rains..no problem Kerala got plenty of premonsoon rains…coastal Karnataka getting heavy rains
Thank u.
Happy birthday deepak.
Thank u
Happy birth day
Thank u sir
No sir… i am student
Sry……
Thank u na
Welcome
At poonamalle 400 ft road. Cloudy.
UAC will be close today
Rains?
Yes
UAC effect!
Yes! Convection rebuilding started vorticity @500,700mb levels nearing chennai!
Many intense ts at machilli radar…….
The southwest monsoon finally hit Karnataka late on Friday night, but the rainfall so far has been scanty due to formation of a low pressure area over the Arabian Sea.
The State capital received good pre-monsoon showers from March to May. The City received 443 mm of rain against the actual forecast of 170 mm, the highest in a decade.

Oho
No more than that….nearly city imd got 48cm..very excess..we got half of our normal rainfall amount..very lucky this year
Cloudy start ot day here at kk nagar
Happy birthday deepak
Hi deepak, wish u a Many more happy returns of the day..
Thank u sir
Ameen, gud and energetic topic..hope the rains come from this uac for us..or for ur sake atleast..
The only factor helping Indian monsoon this year is positive Indian ocean diploe which is nullifying the Elnino effect…..and the skymet depending only on this factor for a good SWM……but my fear is that it may cause severe floods in north and draught in south India… Debatable???
Ameen,
More than anything else, the keeness you show in contributing the daily topic is amazing. You seem to be ever ready , fully charged and say ” Hey, I’m willing” ..Kudos for the spirit shown.
😀
Good towers tomorrow..

As the Arabian sea system is developing into a major system, Is there any chance of it spoiling our UAC?
no..its moving away and UAC nearing us..there will be no disturbance hope so.lets see
Happy Birthday Deepak. Have a wonderful year
thanks
In machilli radar,there are strong rain bands influenced by the current UAC..but not in chennai..y?is UAC still near machilli?
happy b’day Deepak ….!!!
Thanks gts sir
🙂
🙂
Happy birthday Deepak! !!
thanks sir
🙂
Lol .. I am not sir ..
ok na
Happy Bday deepak.. 🙂
thanks sir
2D-gyric map model for Arabian I-95A:
Arabian system (I-95A) if sustains enough strength then will cross the coast at SW-Pakistan at 65E,25.2N. If its a weaker system then it will move in similar direction and weaken in open waters of north-Arabian sea.

Happy birthday cyclonic storm deepak
which cyclone? is it ashobaa??
Bijli
bijli is old, now its sequel to bijli-1??
Could be
thanks jeet sir
Sirrr?
Yet again IMD GFS comes in line with ECMWF s forecast for the Arabian Sea system ….king of medium range models !!!
CAPE values remains phenomenal all along tn ,s.ap coast…and also over north interior tn and s.interior ap
sel next few days we are going to get something. A special day too…..what do you feel
yes pj.. ts frequency is likely to increase in coming days.. chennai,vellore,tiruvallur and s.ap regions may see above normal activity
Deepak….wish u many many happy returns of the day
Thanks sir…
🙂
Last time the same sunday (it was june 8th) the TP meet was organised and a UAC that night battered Chennai. Today another UAC is on the way
Wow.hope so today it happens
Yea ur b.day gift
exactly the same scenario.. even yesterday i mentioned.. last year it was NANAUK in arb and UAC in bay.. tis year near depression& UAC.. more or less in same latitude .
Ellaam Deepak pannina athrishtam
lucky boy!!
Eppadiyo ithamaari solli mazhai vanthaa sari
Today also ts will have its customized route
Will never forget that extreme humid conditions ever ……….discomfort was killing me …….
u were there ah….i remember Selva
Yes I was there very much …u oly showed me blue shades forecast for chennai area @ 850 hPa level …marandhuteengala bro …….
On IMD NWP charts
ok ok.
Many Many Happy Returns (சுதர்ஷன் மாறி சாயந்திரம் பர்த்டே இல்லைன்னு சொல்லாதேபா )
Happy birthday Deepak :))
Happy b day deepak
95A throwing huge convective band just off the coast
Happy birthday Deepak!!
West coast gonna get battered tonight/tom morning
Arabian sea low may become Cyclone. Kerala has received less rains.
Cherrapunji 34 cm today.
Wat hpd to bike? :p
Slight NE movement of the Arabian Low can trigger very heavy rains In Coastal Karnataka and North Coastal Kerala and also many pop ups in Interior Karnataka.
” The low pressure area over southeast and adjoining eastcentral Arabian Sea now lies over
eastcentral Arabian sea and adjoining areas as a well marked low pressure area. Associated
upper air cyclonic circulation extends upto 4.5 km above mean sea level. It would intensify into a
depression during next 24 hours”
what happend? how bad is the injury?
Omg!!! Take Care … Ameen Be Careful Dude…
take care!!
oh how you were looking at the sky while riding the bike is it
Ha ha
My bro was riding and i was sitting @the back. Sudden a bike came in super speed from fornt and it hit me in my leg and went away….
went away ???
Take care my dear go to doctor and have an ATS
What happened
Heavy rains in Hyderabad
rainfall till 8:30am
Uppal IT sez – 54 mm
Begampet IMD – 30 mm
Shamshaabad airport – 30 mm
Take care ….
Thanks….
Rao sir is this correct?
Looks like the UAC comes close today.
So Ameen expecting rains today.
From tonight
On This Same Day Last Year It Was Saturday and Was Highest Temp Of Last Year…
How much dge
42.2c
Thangu
recent gfs brings a very rare track for arb sea system
very very strong cat 3
I doubt it. It may become Cat 1 cyclone.
ofcourse reality differs.. gfs is highly ………
Highly ???….gap filler enna ??
Category 2 approaching the sands of time despite high shear.. !! Is GFS alright ??
They could have put up a caution message like CFS does …
Actually CFS is doing , GFS ???
lolol hahaha…! The one on weather online page right ?? GFS used to be good last year 😦
Yeah yeah ….Would expect GFS to its earlier form ….
Soon they will dissipate it….
Till now, the influx of moist air from mjo is more than that of the dry air from north and hence the system getting developed very slowly, but as the system moving north and the dry air influx will be more in proportion so it will start to hinder the development soon.
At last no model can predict this cyclone.
But GFS forecasts expects moist inflow to continue from SW all along.. It expects the high to remain far too west to directly pump dry air into the system’s inflow.. let’s see
Let us see…as GFS supercomputers take many more parameters as input.
please read what carefully.
Pj sir current situation. Bulk of moisture available in chennai @your favourite levels i.e. 500hpa level
See this img
agreed. No doubt about it. How can u say it is steered by mid level. we have been seeing UAC is steered by 700 hpa winds
Ameen what has SOI and MJO has to do with only Chennai rains…..Why use such experts terms……!
Guys download earth null app. It is too good! Faster than browser earth null. Just Search ” earth wind” in play store
K ameen
Are u sure the UAC is steered by mid level winds.
Yes. I’m observing since wednesday. It is moving towards tamil nadu according to mid level steering
Ok ameen. Lets see
HURRICANE BLANCA
MAX WINDS-105
Will Arabian sea lpa have impact on bob uac?
No it is moving away so no
95A
Steve moving which dir ne or nw
NE
Which place
Global models
Areas jst north of chennai has bright chances of ts today
I’m in nchn
Take care bijji:-)
Then Our Places Deluge!!!
Heavy thunderstorms likely in central AP today, near Prakasam districts and such.
Tomorrow, the trough line will pass right through N TN and S AP areas.. Heavy thunderstorms and widespread activity likely on Monday evening
Tommorrow the wind confluence like last week UAC vellore rains. This time close to Chennai
UAC effect also!
Apart from UAC, the Nallamala hills over there will always favour good stormy conditions
U should also be getting ready with the rainfall sources next few days!!!
Yep gfs is also expecting 84 mm in next 3 days
Rs rao sir pls see new convection rapidly developing over UAC!
Image loop
ECMWF Super computer input parameters
Those are jst scales/observational models/medium thro which thy get data not actual input variables
yep…but derivation of the parameters is completely based on the model data assimilation techniques
Any pull effect rain in tamilnadu due to cyclone in Arabian sea
when there is UAC how can there be pull effect.
When compared to other models,ECMWF uses 3D and 4D Variational analysis is widely and it has much keen attention on
The model orography
The land-sea mask
The sea surface temperature (SST)
The albedo
Aerosols
The surface vegetation
Snow cover
Sea surface conditions
Stratospheric processes
hOT AND SUNNY IN PONDY How much chennai get rain yesterday
My area got 5to7mm
As usual UAC will move noth and weaken
But, this time the UAC moving SW
arb sea system influencing the w.coast rainfall.. they r missing the ws rainfall wich they normally get during onset .. going by the forecast w.coast offshore trough establishing only after 13th june… on the whole tis year onset is not a great start
After the cyclone SW monsoon may regain strength like our NE monsoon
Ws rains ?
widespread rains
Cherrapunji got around 750mm in 48hrs 😦
Avanga katla epavum mazhai thampa
Thats the annual rainfall of Delhi.
Annual rainfall of kurnool
Its annual Rainfall for Kanyakumari to.
Off shore trough to become active and host a UAC by 16th going by GFS… could be first major spell this SWM.
wish you many more happy returns of the day to deepak.
good ..curving band..T1.5
Wow two cloud mass on either side of India, one going to form as a cyclone and the other fighting to survive to give rain to chennai
WML has the nice spin to it. Soon can be Depression
Bijli…ippo kaal epdi irukku?
OMG Cherrapunji 340mm 😦
What’s the surprise there? It’s Cherrapunji.
No surprise just stunned after seeing figures.
Almost daily 300mm+
Lot of Cumulus clouds from SW and some Stratus clouds around. Good sign of TS.
Yes..good sign..looks like monsoon clouds..
But not like monsoon now 😛
Wait till 6pm
After 6pm its absolutely going to be a Monsterous Thunderstorm.
The King has roared again, Cherrapunji gets close to 2000 mm Rainfall in last 10 days
in mm
29.05.2015 – 152
30.05.2015 – 112
31.05.2015 – 121

==============
Total – 1915 mm

The real rain king
Uac is nearing to n tn coast?
better chances for rain for Chennai today, but do not think UAC trough is near Chennai.
Cumulus congestus at 11:30 what the hell is going on
DuraJon is getting ready for recharge…massive electric storm on the way!
Which way boss ?
Meena’s way
Clouds coming from SSW. It should be from NW Right?
Low level clouds are from SSW now.. We have to wait and see the movement of thunderstorms.. Should be westerly or NWerly as u say
UAC nearing TN coast upto kodiakarai
Like the way vadivel says, we just have to move chennai ,right next to cherra..
guess , Mumbai has to wait further because of the LPA. It will pull the moisture towards it and will make mumbai more hot.
