Every year withdrawl of SWM is getting delayed only central India (Orissa, MAHA, MP,GUJ, RAJ) have maximum benefit. If NEM fails SE India will become desert (already Rayalseema is in desertification process).

Very glad to see that SWM is coming back in a good way after a long period of silence. Hopefully it will help all the farmers in central India who are facing a deficit otherwise. Gujarat has so far not received any rains this year. Hope some SWM rain reaches there somehow. May the SWM last until mid October and bring more bountiful rains.

Sir,

What are your thoughts on the way monsoon has behaved this year.
How do you see remaining days of monsoon for Mumbai.It is disappointing till date.

sset said...

Look like one more typhoon brewing in east side - looks like stubborn SWM is no mood for retreating.. blockage for NEM...

Jivata Bhammar said...

Why this monsoon is weak?any special reasons for that?

Hi Rajeshbhai, with the passage of this Weather system (Cyclone Daye), what is the status of Monsoon withdrawal from India? Also, how do the last few days of SWM for Mumbai look? The weather has definitely turned warm and muggy in Mumbai since the last couple of days, typical of end September / October.

Seems vagaries has underestimated BB-11.... First it has stalled withdrawl of SWM impacting NEM.. Another typhoon may spoil withdrawl?

Punjab, Himachal Pradesh, Chandigarh flooded...army on red-alert. Vigorous torrential 3 digit widespread rains (300-200mm) of rain. Schools closed.

BB-11 has unleashed bounty rains for Orissa,MP,Chattisgarh, Maharashtra Vidarbha, Rajasthan, UP, Punjab, Haryana, Himachal Pradesh..... Who says Rajasthan,Haryana are dry places - it was in past - now no more since last 10 years climate change pattern

Typhoon Trami churning fast. Will this again stall SWM withdrawl ?

Hi SSET
Haryana and Rajasthan are arid places. Even after this depression which is an unexpected parting gift from this monsoon, both these places have received less than normal rainfall this year.
Haryana is 11% below normal.
Rajasthan is 5% below normal.

Here is the link.

Saurabh -> why only focus North? South east Inida- Rayalseema (Cudapah, Chitoor, Anantapur..) are deficit by 60%, if NEM fails then it become 90%! worse than Thar desert. Many places over TN, SE KAR are waiting for NEM to start.)
