Rajesh, this has been the longest dry monsoon period that I have seen in Mumbai. Atleast going back to the 70s as per my recollection. What is happening ? How do you see the evolution over the balance of September? Especially Mumbai and North Gujarat, Kutch ? Some people are forecasting a withdrawal from next week. Is that correct ?

It seems August and September rains are showing reducing trends in last some years though last year was good. It has been really dry this season.Interiors have got decent rains and coastal area have got less rains if I am not wrong.
Really bad year for some places in gujarat which have not even crossed 100 mm total for the year.

Akshay Shah said...

This time Arabian sea is surprisingly very silent. Over the years have seen Arabia sea not cooperating for a good monsoon over coastal areas but this time its very bad for northern parts of western coast & western India in general. Not much help as offshore trough has been absent for majority of the period this monsoon. All this with no El Nino and neutral IOD requires some study as what shall happen if parameters are negative?

Rajesh sir, pls guide on this one month left of Sep? Delhi NCR is getting more rains than Mumbai in Aug - Sep this year!!!

Abhijit Modak said...

Yes, Vinod & Akshay. West coast Offshore trough inactive since 18 July so it is now almost 50 days without offshore trough. And further till 15 Sep also not forming as per models output. So we can say west coast main rain driver offshore trough absence from last two months !! Which is unique phenomena like for this monsoon so Mumbai or we can say whole west coast from Dahanu till Mangalore (except Kerala) is in deficit for Aug & Sep till now and having prolong break monsoon phase (though seasonal wise normal due to June to mid July excess) . at least me personally never saw such long break phase as no revival was seen so not a single 50 mm rainy day in last 50 days has been witnessed !

Akshay Shah said...

I don't wanna put anything negative here but this one guy who was constantly posting negative comments about konkan mumbai and gujarat is also absent along with our fav offshore trough. Hope out if the 2 offshore trough will be visible in next 25 days

sset said...

Worst fear is SE India - I fear repetition of horrible 2016 drought. SWE should withdraw fast. Not sure how much is true el-nino favours NE monsoon. Other hand torrential rains over Orissa - 400mm in 24hrs! very good rains over northern and NE India- series of systems.

ANOOP RAWAT said...

As akahay shah said Delhi Ncr getting good rains in September.

Whole Konkan coast of Maharashtra & Goa including Mumbai seeing one of weak monsoon since Aug. No typical revival was seen after thir...
