Detailed Weather forecast from Friday 29th September to Tuesday 3rd October - Tracking the Monsoon withdrawal

Some much needed rainfall has occurred over interior and rainfall-deficit Maharashtra during the last 10 days, although the deficit will persist in some districts. 

Mumbai: Retreating monsoon thunderstorms are possible until 1st October, after which the chances of rainfall decrease. Only isolated thunder pop-ups likely around Ghats during 2nd-3rd October. 

Dry air from north/northeast at 700 hP and 850 hPa will engulf most of north Konkan and interior Maharashtra after 3rd October. 

Monsoon may withdraw around 5th-7th October from Mumbai and north Konkan. 

October heat will set in with max temperatures rising to 32-34C for MMR. Nights can be around 24C, slightly cooler for Thane district. 

Pune: Chances of retreating Monsoon thunderstorms till 2nd October, after which isolated thundery activity may be confined to Ghats till around 3rd/4th October. 

Monsoon withdrawal may happen by 7th October. 

Daytime temperature may rise to 31-32C after the stoppage of thunderstorms. Night temperature may dip to around 19-21C, with rural areas/Ghats seeing a further dip.

Note: Although weather is likely to be mostly dry, surface winds for Mumbai and Konkan may still remain weak northwesterly, so moderate humidity may persist. The dry easterlies may start from the second week of October.


Due to persisting dense clouds/thunderclouds, a cyclonic circulation has formed over Arabian Sea off the south Konkan coast - moderate-heavy rain/thundershowers likely for south Konkan and Goa for next 2 days, with localized very heavy rain. It may become a low pressure area.
It won't be able to push in moisture till Pune/Mumbai, otherwise rain/thunderstorms would have persisted during the 1st week of October. 


Marathwada and Vidarbha: Some rain/thundery activity may continue till 2nd October for southern districts, and dry weather after that. 

Daytime temperature can rise to 33C after 2nd October.

Eastern parts of Vidarbha may see some rain till 3rd October. 

Gujarat: Rain/thunderstorms from the retreating Monsoon will persist till 30th September near Bharuch,Vadodara, Saurashtra, Surat, Valsad regions. Few places near Surat/Valsad and south Saurashtra can see localized thunder till 1st October. 
Monsoon likely to withdraw from entire Gujarat by around 3rd/4th October. 

Dry weather, and October heat with temperatures rising to 34C is possible after Monsoon's withdrawal. Some regions in Kutch may touch 36C. 

Parts of Kerala and coastal/Ghats of Karnataka can receive moderate-heavy rain over next 3 days.

A new low, BB-10 is developing over north Bay of Bengal. It will move west/northwest and bring moderate rain for West Bengal, Odisha Bihar, Jharkhand, north Chhattisgarh, eastern parts of Vidarbha and Madhya Pradesh, east and central Uttar Pradesh till about 3rd/4th October. Western areas of Uttar Pradesh may also see few isolated showers. 

Himalayan regions of central and eastern Nepal, Sikkim, Bhutan, and Arunachal Pradesh can receive heavy rain - avoid travel. 

Many parts of northeastern states of India can receive good rain in this period. 

Punjab, Haryana, Rajasthan, Delhi NCR: No rain is expected, Monsoon withdrawal may be announced in a day or two. 

Western Himalayan states and UTs may receive some rain/snow from a weak Western Disturbance from 30th September to 3rd October.

27th September..Fast Changing Scenarios:


Chart compiled by Vag. Gokul.

Fast Withdrawal indications:

Subtropical ridge at lower levels have started extending eastwards from the desert areas towards NW India at 25°N indicating the seasonal shift. As a result, .Bay system may not travel west into central India from east coast.

*BB 10 not coming inland is a big miss and may allow an early SWM withdrawal from North, Central and Peninsula India.

*Some more moisture inflow is needed into Maharashtra to sustain rains in October first week..

*Arabian Sea may not see any strong UAC off the coast to push southerlies...

*Retreating thundershowers also starting with NE flow directly...so few days of active ⛈️ thunder activity before dry weather in peninsula and Maharashtra. (If  there would be E/SE component in TS then may have persisted longer).

Forecast till 1st October:

*Monsoon withdrawal from Rajasthan, Punjab, Haryana, JK, HP  and Delhi by 28th September.

Dry weather in Northern, Central States. Eastern India will get some rains.

Most of Western Ghats, Madhya Maharashtra belt and parts of Marathwada and Vidarbha to receive thundershowers till 1st October.

Mumbai:

*Retreating Monsoon afternoon/evening  thunderstorms expected for Mumbai and Pune regions. These thunder activities may persist till 1st/2nd October.

*Some areas can get localized heavy rain with gusty winds.

*Due to fast developments in the High pressure spread, Mumbai Monsoon may withdraw a few days earlier than anticipated. Could be around 5th October for total withdrawal.

Current El Nino..2023.

Many queries are cropping up on the "El Nino" topic ...Firstly, what is El Nino?

Simply put..An over heating of a tongue of water off the South American Coast.

Caution: All El Nino years may not necessarily mean a weak Monsoon, as seen in the chart below 👇



ONI & El Nino: Characterized by a positive ONI greater than or equal to +0.5ºC.

 La Niña: characterized by a negative ONI less than or equal to -0.5ºC. 


By historical standards, to be classified as a full-fledged El Niño or La Niña episode, these thresholds must be exceeded for a period of at least 5 consecutive overlapping 3-month seasons.

El Niño Advisory ...How is it shaping up ?



*El Niño conditions are observed.

* Equatorial sea surface temperatures (SSTs) are above average across the central and eastern Pacific Ocean. The tropical Pacific atmospheric anomalies are consistent with El Niño. 

*El Niño is anticipated to continue through the Northern Hemisphere winter (with greater than a 95% chance through December 2023-February 2024).*

The Indian Summer Monsoon 2023 was partially affected by the current developing El Nino. 

The monsoon started off weak, with  June being -9%  July, impressed with +13% . August saw erratic activity, with -36% for the month.

So far this September, surplus is +9%,

All India Monsoon is at -7%.  Maybe a better picture will emerge by this month end...for the overall Monsoon Season. 



Wednesday, September 20, 2023

Region wise Monsoon Report till today 20th September:


The monsoon started off weak, with  June being -9%  July, impressed with +13% . August saw erratic activity, with -36% for the month.

So far this September, surplus is +9%,

All India Monsoon is at -7%.  Maybe a better picture will emerge by this month end...for the overall Monsoon Season. 

Now,  with multiple weather systems , BB-8, BB-9, UAC over Rajasthan, more showers across the country are expected this month.

The ongoing rainfall this month, is a blessing for the Summer crops, following the driest August in over a century. 

This year, the withdrawal date is delayed....Normally the Monsoon starts its reversal from Rajasthan on 17th September.

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

Maharastra Monsoon upto 20th...👇

Mumbai: Next few days the current pattern will continue with occasional showers, some with thunder. Weekend forecast on Friday...

Interior Maharashtra   Many areas in Vidarbha, Marathwada and Madhya Maharashtra regions likely to get moderate rain/thundershowers over next 3 days. 
Rainfall may not be uniformly distributed
 Ch. Sambhajinagar can see moderate rain/thundershowers tomorrow 21st and Friday 22nd.

 Today's [ 18th] rain in ,Gujarat 


BB 8 continues in Gujarat...

Visavadar (junagadh) reported 185mm during last 4 hours ending 10am


And Kutch...😳


Sunday, September 17, 2023

Posted 17th Night:

BB-8 continues its Westward track pouring extremely heavy rains in Rajasthan, M.P. and Gujarat.👇

Ahmedabad,Bharuch and Vadodara heavy rains were pre warned in Vagaries "Latest Snippet " yesterday.
 

However, the "pull effect" Westerly winds towards the system from the Arabian Sea was weak (not enough gradient).Closely spaced isobars mean strong winds; widely spaced isobars mean lighter wind.
The Westerlies can strengthen a little bit as the location of the Low shifts towards Kutch
 


Hence the rainfall over North Konkan (Mumbai) was not as per our expectations.
.
Mumbai did not receive the expected amount of rains due to poor Westerlies. We expected around 40 mms cumulative this weekend, but averaged around 30 mms between North and South Suburbs.

Monday 18th, will get some regional heavy showers. From 19th -22nd ( Rest of the week), we can expect showers in irregular intervals, not steady, in parts of city. Sunny  periods in between.
This pattern of rains will continue through the week.

Pune: The coming week will be partly cloudy with light rains in parts of Pune.

Sambhajinagar: Light to moderate rains will continue for the next 4 days. There will be no danger of fields getting waterlogged. Slight increase from 22nd.
Rainfall this season till today : Phulambri 384 mms ( 78%), Waddod Bazar 358 mms ( 73%)
संभाजीनगर : पुढील 4 दिवस हलका ते मध्यम पाऊस सुरू राहणार आहे. शेतात पाणी साचण्याचा धोका राहणार नाही. 22 पासून वाढ होण्याची शक्यता. या हंगामात आजपर्यंतचा पाऊस : फुलंब्री 384 मिमी (78%), वडोद बाजार 358 मिमी (73%)

Bharuch: After getting good rains ,( Netrang 52 mms, Bharuch 35 mms), the rainfall intensity will decrease from the coming week...18th onwards.
ભરૂચ: સારા વરસાદ પછી, (નેત્રંગ 52 મીમી, ભરૂચ 35 મીમી), વરસાદની તીવ્રતા આગામી સપ્તાહ...18મીથી ઘટશે.

New Low...BB-8 developing in Bay....

Mumbai: The Monsoon is playing " Come & Go" with Mumbai. 

*June with low rainfall,  

* A drenched July

*A long dry spell in August, causing concern and worry..and then a wet spell, bringing hope and smiles.  

 *September: A wet beginning and a dry spell, and now, another dry, hot spell ...

The Mumbai lakes and dams level reported at 6 am on 12th September 2023 is 97 % of the total. 

The quantum and intensity is still unsure, but will be able to get some inclination as the Low crosses the coast on 13th.( Maybe in excess of 100 ~150 mms between 16th ~20th.But we can ascertain that later).

As said earlier in Vagaries, a good spell in September should not be a reason to worry for Mumbai  !

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

Interior Maharashtra is in for good bountiful rains. 

From 16th, for the next 3/4 days, Vidharbh, Marathwada, and Madhya Maharshtra will receive the much required rainfall for the standing crops.
