something needs to trigger the storms.. in the evening, storms will form through convection, but mainly in the interiors. But overnight, the low pressure will trigger thunderstorms. NEM bands can also form during noon, but chances are less today as the LPA is weak and another one is already there in S.AP

How can the Depression move? IMD has not even announced a Low Pressure yet.

sampathcaits not happening today. The event is set for tomorrow.

Ennore – 105 mm is confirmed. Ponneri data is either not available or IMD not published it yet
Sud T.nagar cat5hurricane What a comedy !!!!
Jigga
NEM cloud masses will form overnight..
cat5hurricane Sud T.nagar Oh i see then you are a businessman …
Why so? Why not daytime?
Jigga

NEM bands can also form during noon, but chances are less today as the LPA is weak and another one is already there in S.AP
Sud T.nagar Jigga SUSA you mean YS in SAP
rame1975 Sud T.nagar Jigga
yeah, the cloud mass in the SAP is the one that will prevent major storms from forming now
cat5hurricane rame1975 What are you making comedy out of me ??? Like VADIVELU saying… LOL !!!

Sud T.nagar Finally what both of you agreed upon the LPA position and moving direction ?
