Weather Knowledge Site updated with No.58

The South Asian Monsoon 3D Large-scale circulation is now fully established:

While,June has been an above normal rainfall period for the country as a whole with a cumulative rainfall departure of +9%, there were regional variations in the rainfall pattern with north east and southern peninsular India ending with below normal rains. 

Meanwhile, the latest sub-seasonal scale forecasts from global NWP models for the next 2 weeks indicate that the pattern of monsoon rainfall anomalies over India and the larger south Asia could be exhibiting regional differences. While the forecasts continue to indicate an active rainy spell for much of the core monsoon zone (central India) due to an active Monsoon Trough with frequent westward propagating transient lows, the peninsular India could be under the influence of suppressed rainfall conditions.

With the onset phase of the current year's South Asian Monsoon now drawing to an end, the 3D large scale monsoon circulation associated with it is now completely established as seen from the latest available observations. Several semi-permanent features like the large scale upper tropospheric meridional temperature gradient, Tropical easterly jet, low level monsoonal westerlies, large scale upper level divergence over NW Pacific, Mascarene High, Monsoon trough,etc., have all established. One can see a completely established Baroclinic atmospheric structure over South Asia. Interesting days ahead with anomalies across spatial and temporal scales that would interact with this established Monsoon background.

But, the system may keep the west coast and Gujarat somewhat rainy. Interior Maharashtra and Gujarat  will continue to lesser intensity rainfall..

Mumbai: Next 4 days will be partly cloudy. with a few passing showers, some heavy in localised areas.We may assume 15-20mms/day. No meaningful rains to worry.

Pune; Partly cloudy and some light showers ...morning /afternoon.

Pune will see light to moderate passing showers and monsoon weather...cool days .Expect 25-30  mms next 4 days cumulative.

Sambhajinagar: though more rains are required, the next 4 days does not indicate much meaningful rains. Passing showers accumulating just 20-25 mms in next 4 days.

संभाजीनगर: जरी आणखी पावसाची आवश्यकता असली तरी, पुढील ४ दिवसांत फारसा अर्थपूर्ण पाऊस पडण्याची शक्यता नाही. पुढील ४ दिवसांत फक्त २०-२५ मिमी पाऊस पडण्याची शक्यता आहे.

Bharuch: Will now see some reduction in rains next 4 days. Though there will be showers, it will be lesser frequency, wit around 25 mms cumulative next 4 days. Warmer nights though.

 20th June...Not a Usual Scenario 

Monsoon Trough (Dynamic Low) gets established for the first time this monsoon season: 

-------------------------------------

The Monsoon Trough or the Dynamic low is getting established for the first time this monsoon season over the Indo Gangetic Plains. The mechanism is an indication of the arrival of moist monsoonal air mass and related physical processes over the northern boundary of the Indian subcontinent. With this, the advancing phase of summer monsoon rains is nearing completion. The latest update from IMD indicates that the monsoon isochrone has covered most parts of Uttar Pradesh and parts of north western Himalayas in the past 24 hours. Satellite observations indicate formation of persistent low to mid level cloud layers on a large scale to the south of the Monsoon Trough axis. Rainfall observations over the core monsoon zone show that the region has been experiencing huge positive rainfall anomalies in the past 4-5 days with area averaged rainfall being close to + 2 standard deviations. Meanwhile, NWP model forecasts continue to indicate an early advance of Monsoon over the north western regions of the Sub Continent. 

Analysis and Report of Latest Scenario by Vagarian Gokul. 

Weather outlook from Wednesday, June 18 to Friday, June 20 - Active Monsoon conditions!

Twin low pressure systems...one over Gujarat (AS-2) and the other near West Bengal (BB-3).

BB-3 to move west - Monsoon will advance over entire eastern and central regions covering Bihar, eastern UP and Madhya Pradesh.  

AS-2 low is keeping moisture confined to Gujarat/Saurashtra, so rains along the Konkan coast including Mumbai have eased on Tuesday 17th June. 

Passing showers expected across Maharashtra and Goa coasts - likely to increase from tomorrow mainly for North Konkan and south Gujarat regions.

Mumbai: Moderate to heavy rains expected in MMR region, with some gusty west-southwesterly winds at times. Average rainfall can be between 40-80 mm/day across the city and suburbs. Few regions in Mumbai/Thane and Palghar districts may get heavier rains. 

Ghats can receive heavier rains, possibly 100 mm/day or higher. 

Pune: Moderate rains (around 20 mm/day), cool winds and pleasant weather. 

Next 3 days - Nashik region is likely to receive heavier rains than Pune. 

Gujarat: Rains likely to reduce in Saurashtra and Kutch regions as well as Ahmedabad/Gandhinagar after Wednesday, 18th June.

Delhi NCR region, Western parts of Uttar Pradesh and eastern Rajasthan can receive pre-monsoon thundershowers.

 11th June ...afternoon post

Vag. Dr.Vineet informs:

For the 1st time after 2012, no cyclone has formed in north Indian Ocean (Arabian Sea+bay of bengal) in the pre-monsoon season (April-june).

Vag.Shreyas informs:

Pacific system activating SW winds over Bay...Somali Jet gradually increasing in strength so Arabian Sea branch will get activated soon...the current ridge will break down and westerlies will strengthen from 13th.

UAC seen at 700 hPa over east coast - likely to move west

The UAC will give moderate-heavy rain over parts of Andhra Pradesh and Telangana. 

Next 24-36 hours: chances of some heavy rain/TS for south Madhya Maharashtra and north Interior Karnataka...possibly even covering parts of Goa and South Konkan coast/Ghats.

Vagaries confirms its view;

Mumbai/Pune Rainfall frequency and intensity will increase from 13th June and will continue with better rains next 7 days.

Sambhajinagar will see an increase in rainfall frequency from 13th for next 7 days. 

Gujarat Region will get dry weather till 16th at least. Maybe with  rains on South Gujarat coast: Valsad/Surat and Bharuch regions from 14th..

Monsoon may slide into South Gujarat.

8th June.... Overall SWM Deficiency is - 25%

We see Monsoon progress stalled at Mumbai since 26th May. 

Moved upto Mumbai by 26th May, not as a technical Monsoon current, but temporary advance helped by the Low Pressure AS 1.

Later on 3rd June, aided by W/SW winds upto 700 depth, we got a "feeble" advance of monsoon upto Mumbai.

Now with the system having fizzled out after 29th May, there is no supporting system to revive the Monsoon. Hence, we expected the break and decrease in rainfall all along. {Due to moisture incursion, however there were sporadic sharp spells in Maharashtra,}

No meaningfully revival is seen along the West Coast, as the off shore trough remains dormant  or absent.

Till Friday, 13th June no proper Monsoon Rains , the June types, will be possible along Maharashtra, Goa and Karnataka coast, interior Maharashtra and N.I. Karnataka and Gujarat.

Belgavi, Solapur and Adjoining towns will get regular " pop up" thundershowers.

Bangaluru can get the local thundershowers on a few days in the week.

Mumbai: The coming week remains without the Typical " Mumbai Monsoon " rains. Showers in parts of city, not widespread possible.

No meaningfully revival of proper Monsoon rains till Friday 13th June.

Pune: Partly cloudy. with some showers in the parts of city. Properly revival of rains from 12th June only.

Mahabaleshwar rainfall increasing substantially after Friday 13th.

Bharuch : Almost dry, with no meaningfully rains till this weekend, heating up the Weather. Heat upto 42-in 43c expected in Ahmedabad.

We are concentrating on the staggering Monsoon, but the coming week, 9th onwards, can see a major Heat spell in Rajasthan ( > in 45c) and Delhi Punjab around 42-44c. The lows May not go below 30c!

This is in liueof the missed heat waves in May.😉😉

 Vagaries' Views:

IMD AWS  page is not available for public, IMD Rapid Satellite section is also is not available.  When other agencies like ECMWF are fully to open data to foster research IMD has opted to make data inaccessible. What could be the thought process behind these decisions.

It's very important to get real time data  for public during emergencies. Keeping this information confidential/inaccessible makes it illogical! And there was no point of developing this website with this data at all if you can't keep it open for all

What IMD has said earlier:

"Mrityunjay Mohapatra (IMD DG) is spearheading a major expansion of AWS and ARG stations through the WINDS program. This plan will boost station numbers from a few thousand to over 200,000 across India, aiming to deliver timely localised weather data directly to farmers and the general public. The enhanced network is expected to fill existing data gaps and significantly improve forecast accuracy."

 AWS and ARG data now not accessible to general public and farmers

These AWS ARG are only source of weather data for farmers. Why does IMD restrict it to access? 

We don't think the National Institution like IMD needs to worry about private weather enthusiasts or be threatened by them. In fact all private meteorologists take data from IMD stations !

Met department must think twice on this decision.

6th June Evening

Outlook for Weekend 7th-9th 

Mumbai: 2-3 Moderate showers daily. Day warm at 33c and stuffy warm  at 25c. Expect around 30-45 mms cumulative rainfall in 3 days. Distributed in the parts of city. 

Pune: Rainfall with some heavy falls...Moderate to heavy thunder Showers in various parts of city. Days better at 31/32c and nights at 22c. Cumulative rainfall for 3 days around 30-35 mms distributed in city.

Sambhajinagar: Some increase in rainfall from 7th to 9th. Sharp showers can help to start the sowing now, as fields are ready.

Mahabaleshwar: Cool foggy days with occasional rains. Cumulative rains could be around 50-70 mms.

Bharuch/Valsad: A thunder shower on Saturday, Lesser rains on Sunday/Monday.

मुंबई: दररोज २-३ मध्यम स्वरूपाचे सरी. दिवस ३३ अंश सेल्सिअस तापमानावर आणि २५ अंश सेल्सिअस तापमानावर उष्णतेची शक्यता.

शहराच्या काही भागात ३०-४५ मिमी पर्यंत ३ दिवसांत एकत्रित पाऊस पडण्याची शक्यता.

पुणे: काही ठिकाणी जोरदार पाऊस... शहराच्या विविध भागात मध्यम ते जोरदार मेघगर्जनेसह पाऊस पडेल.

दिवस ३१/३२ अंश सेल्सिअस तापमानावर आणि रात्री २२ अंश सेल्सिअस तापमानावर चांगला राहतो. शहरात ३०-३५ मिमी पर्यंत ३ दिवस एकत्रित पाऊस पडेल.

संभाजीनगर: ७ ते ९ तारखेपर्यंत पावसात काही वाढ. शेत तयार असल्याने आता पेरणी सुरू करण्यास जोरदार सरी मदत करू शकतात.

RAINFALL FOR THE PERIOD 1-3-2025 to 31-5-2025

 

31st May:

Weather wise, an event full May for Maharashtra...specially for Mumbai and Pune.

1. 26th May, An earliest ever Monsoon setting date for Mumbai. The previous earliest was May to 29th in 1956, , . 

However, this year, we announced a " temporary advance". Now, this has never been termed before anytime. Looking at the initial surge , due to the meandering Low pressure system ( AS 1) over Maharashtra, we coined this term " temporary " as we saw very heavy rainfalls in Mumbai and Interior Maharashtra (Pune Region). 

(all records and figures in previous posts).

Showing a image of our 26th blog post :👇

Rainfall Total of May 2025 (with normal in Brackets)👇

Mumbai Scruz: 378 mms ( 18 mms)....Scruz record of 388 mms in 2000 hold good ! 

Mumbai Avg. May month Average Max in 2025 is 33.5c...Day/Night Average 30.0c...Normal Average is 30.5c

------------------------------------------------------------

2. Pune:

One of the coolest May on record for Mumbai & Pune....With coldest May Day ever for Pune at 24.8c on 27th...

2025 May Month Max Avg  is 33.2c Normal is 37.3c

And sure enough, the rains have drastically reduced after 29th.

The days got warmer..as the Monsoon current weakened..

 30th May

Depression BB 2 Location

Well Done IITM..and Prof Mukhopadhyay and his team !

How India’s cutting-edge weather forecast system was built from a lab in Pune

------------------------------------------------------------------------

29th May:

The Depression, BB-2, has crossed into the West Bengal Coast. Will track N/NE.

 

Very heavy rains now will occur in Bangladesh and NE States.

The Axis will move Northwards, As a result>

 30th May - 4th June: 

Mumbai, Pune , Marathwada and Gujarat will see little rainfall. Few Passing showers for Mumbai. 

Hotter days and nights.

Opportunity for completing any pending civil work and water proofing👇

----------------------

Current Winds as on 27th with Monsoon Axis:

..From 29th to 7th June.Rains almost to negligible in Mumbai, Pune, Interior Maharashtra, Sambhajinagar and Bharuch.

Axis and winds expected to shift Northwards ..creating a somewhat hiatus in rains 

 The southwest monsoon made its earliest entry into India this year, hitting Kerala on 24th May and rapidly advancing (temporarily) to Mumbai by 26th May, its earliest arrival.

Fueled by a depression over the Arabian Sea, the monsoon brought record-breaking rainfall to Mumbai.

Colaba recorded 472 mm, surpassing the previous May record from 1918 (280 mms), while Santacruz reported 347 mm.

While rainfall will now reduce, intermittent showers and overcast skies are expected.

A trough off the Konkan coast may keep rains active, but the worst seems to be over for now.

Cool Summer Days in Maharashtra ...27th May..Coldest May Day ever in Pune at 24.8°c 

**Mumbai (CLB) 27th Morning 24 hrs rain: 161.9 mms

May total: 456.5 mms. (Departure from Normal: +446.7 mms)...Previous May Month record 280 mms in 1918.

**Mumbai (SCZ) 27th Morning 24 hrs Rain:  144.2 mms

May Total: 342.0 mms (Departure from Normal +329.6 mms)... Previous May Month record 388 mms in 2000.

**Pune may total as yet on 27th:218 mms... Previous  may record 182 mms in 1933

26TH MAY

MONSOON ENTERS INTO MUMBAI AND PUNE AS A "TEMPORARY" CURRENT.

WE TERM "TEMPORARY" AS EVEN AS RAINFALL IS HEAVY, IT IS NOT STABILISED AS PER CRITERIAS. HENCE THERE MAY BE A BRIEF SCALING DOWN IN RAIN INTENESITY FROM 29TH MAY, FOR A WEEK/10 DAYS.

This could well be the earliest Monsoon Date arrival In Mumbai and Pune.
