Sir how much chance of rain in Gujarat for next 3 to 4 days?

Vinod Desai said...

We have got some rains after 7 pm to 10 pm could be around 40-50 mm.

Anki said...

Patel hiten can u specify which area of guj?

sset said...

Entire night it rains pounded over Navi Mumbai (150mm i guess) - this must be wettest september, all 4 moths june-sept MAHA received excess rains..
rains continues to elude south west coast (KER,coastal KAR...leaving cauvery dry)
Now as vageries forecast another low for konkan that means no rain for south...
Looking at this Mumbai annual may reach 2500-3000mm!

Cumulus arjun said...

Sir, As per MCGM site, Goregaon (W) topper at 108 mm yesterday, followed by Andheri with 72 mm and Dindoshi (Goregaon E) with 70 mm rainfall

Apologies I still feel many south Indian places are in process of desertification.
if we see NEM are so weak only after 4-5 years NEM are good for instance 2005,2010, since SWM failed over southern india - NEM is big question. After sep 25 low we do not know...all rouge system like Hudhud,Phalin,Western disturbances ensure no peace for NEM...

raining non stop over navi mumbai--- seems no stoppage of rains....

Rawat said...

Sir, can we expect light rain in NCR around 21st

I am really intrigued where you get your information from. Please refer to this link
from IMD Chennai regarding north east monsoon for Tamil Nadu. Here is the link

Here is a page 2 from the same report.

Right from the year 2004 North east monsoon is either normal or excess till
2011 over Tamil nadu and Puducherry. Perhaps this best epoch in NEM
2004 +1
2005 +79
2006 +15
2007 +21
2008 +31
2009 +12
2010 +42
2011 +23
2012 -16
2013 -33
2014 -2

2015 numbers are not mentioned here but we all know it was a huge surplus.

There is absolutely nothing to suggest desertification of South India is underway.

Posted 31st Night: Mumbai weather expected this week in city. 1st Feb - 4th February  Windy evenings, Hazy warm days and just about comfort...
