Particularly heavy rains are possible in the districts of Dakshin Karnataka, Hasan, Kodagu, Mandya, Tumkur and Bangalore.

Bangalore can expect heavy thunder showers and squall on the weekend.
On Sunday, a vortex may form in the trough, around S.I. Karnataka, hence I would expect heavy showers for Bangalore on Saturday, Sunday and Monday.

BANG received only 15mm of rain on saturday. Forcast was "Very heavy rain". Now when proper monsoon sets during june-sept, BANG/interiors of KAR will not receive any rains. Maximum gains have to be made only during pre-monsoons.

But Rajesh forcast was on-spot- GREAT.

Nagpur Star said...

Hello Rajesh,
Usual weather for Nagpur with 3rd consecutive day of 47+ deg c temp. In local language it is called the Nav Tap or nine continuous days of heating. I dont know if its true. But surely we are in the peak of summer for Nagpur. When do you see some drop in temperatures. Are there any chances of Premonsoon showers in May or early June.
Thanks for this wonderfull website.
Amit From Nagpur

rajesh said...

Amit: I see the Nagpur peak temps decreasing by 2/3 degrees from Wednesday, as winds direction change.
The odd thundershower can always "pop up", maybe around end May, as moisture incursion will increase.

Thanks guys for the Bangalore report..

Pradeep: Your Karnataka report is always welcome, as it is exhaustive and shows the details nowhere else available..Great !

rajesh said...

Sam: Monsoon advancing into Maldives..keep tab on "monsoon Advance" Page..

Vijayanand said...

Arun Kumar said...

hailstorm reported @ ITPL,Jayanagar

Vijayanand said...

Rain stopped. It rained heavily for 20 min in BTM layout. Water logging every where.Severe traffic jam started now.

Vijayanand said...

Very gloomy over NE again. Appears like MG road and other central business district is in for a big deluge.

Vijayanand said...

Heavy rain started again in south bangalore.

Vijayanand said...

The whole city got good rain today. From ITPL to Jayanagar - From Hebbal to Ecity. Believe this would perhaps be the last of the pre-monsoon rain.

2013 pre-monsoon has been good in bangalore.
