@Rajesh
As per IMD daily report, the hottest place of late has been Bhira. It was 39 celcius a couple of days back, yesterday it was 38.

Can this be explained away by bad instrument or there is something to it.
If there is something to it then the first 40 celcius of the sub continent has to come from here.

Rajesh, think you meant cold wave will be felt above the line - its written- below the line

rajesh said...

Saurabh: Bhira readings, both minimum and maximum are noticed to be wrong and mis-leading. The instrument needs recalibrating..i have been noticing this fault for a long time now..and had mentioned it in vagaries some time ago.
Another faulty instrument seems to be that of Malegaon.

Emkay: Cold wave effective above the line i.e. North of the line...

Hi rajesh, As per your blog...had a brief heavy shower in our area last night at about 8 pm. Some areas received light rains, others heavy :)

Neeraj said...

What is the latest regarding weekend rain here ? Will J3 do the trick ? And what is the chance of snow at higher elevations (say above 6500 feet) ?

rajesh said...

Neeraj: Sure sign of rains for Kathmandu by Friday...J-3 sustains till Nepal.Snow in Western Nepal more heavy and widespread..
Thanks Tyrone for the report..
