Rainfall on Monday (Daytime)..




Posted Sunday Evening:

A cold Sunday for Indore, with 98 mms from 8.30 am -5.30 pm IST, and the day's max at 23c....Bhopal saw 29 mms in the same time period.
Some heavy rainfall amounts in cms as on 8.30 am Sunday for West M.P.>.
NARSINGARH 39, UJJAIN-AWS 32, SARANGPUR 31, BADNAGAR 25, DEPALPUR 23, BADNAWAR 19, SHAJAPUR-AWS 17

The UAC has now descended as a Low over North M.P. and adjoining U.P. (Not numbering it as BB-3, as it has originated on Land). System is likely to persist in same position for another 12 hrs, before merging with the Axis , somewhere near Guna.

Next 2 days Outlook:

Expecting increased activity for Akola and Aurangabad district.

West coast from Surat to Kerala will see enhanced rain actvity. Subdued rains in Odisha. Gangetic Bengal, TN and interior Karnataka.

Tuesday 21st: Rainfall more likely in East Rajasthan and adjioing M.P. and Northern Gujarat.
Subdued in East M.P, Int Karnataka and TN.

Moderate rains spread to Coastal Sindh (Karachi) on 21st/22nd.

Mumbai: Having missed a good chance to see enhanced rains (due to certain adverse factors), I see no reason why Mumbai cannot get increased rainfall from Monday...city should get at least 30-40 mms on Monday and Tuesday, with thunder.

Pune: Monday and Tuesday has chances of moderate showers in parts of city. Around 7-10 mms possible in some areas.

Goa will continue to get Showers and monsoon weather with around 30 mms/day.
Surat:Rainfall increasing form Monday (maybe evening)...and good rains thru Tuesday. Would expect around 50-55 mms cumulative Monday and Tuesday.

Ahmadabad: Breaking a dry spell, Chances of thunder showers on Monday and Tuesday. Expecting around 20 mms/day.

Not much chances of rains increasing in Hyderabad (India) and Bangalore next 2/3 days.

Karachi and Hyderabad (Sindh) will get dry weather till Tuesday, but can expect a shower in the vicinity or around on Tuesday night or Wednesday. Around 5 mms.
