Wednesday Morning 10 am IST:
BB-2, stationary as last night...15N and 91E....25 knts....same expectations ,no changes in estimate

Inland trough has shifted slightly Eastwards, approx over Telengana thru adjoing Karnatak and Westrn TN

Posted Tuesday Night:

Low in Bay now lies at 15N and 1002 mb and 25 knts winds at core.
The Map shows the dry air tring to "invade" from the SW of the system. The wind shear in the West and South of Low is likely to push the Low in a N/NE track, initially and then curving NE.
It will pull the SWM Northwards, and quickly bring it to the Myanmar coast up to 20N.

The effect of the system, to an extent, has advanced the SWM into the Maldives. Kadhdedhdhoo recorded 66 mms and Kadhoo 22 mms. Winds are expected to gust to 35 

The rains over Goa and N.I. Karnataka, will last for 1 day more on Wednesday. The trough currently running from MP to the Arabian Sea runs thru South MP, South Mah and Goa. 
This will shift to its normal perpendicular position from Thursday, and we see the rainfall pattern shifting Southwards towards S.Karnataka and Kerala.

Mumbai, no change in forecast ( Put up on 19th on Mumbai Page).. From 35c in the day, we see the days to around 33c, but stuffy humid nights at 27/28c...and partly cloudy.

Kolkata, will see the peak heating on Wednesday/Thursday. Maybe 42c....and then pre monsoon showers on 25th May.

From Thursday, the Sindh region of Pakistan starts heating up, and reaching 46c by friday 23rd, and 50c by May end. heat wave spreads to rest of Sindh and Balochistan.
Hot weather for 22nd in Gujarat and Rajasthan. Entire NW and North India in the 42-44c range, but going above 45c in UP and Rajasthan from 23rd/24th May.
