Evewrest: Enso conditions refer to El Nino or La Nino..that is warming/cooling off the Peru coast. IOD is the temp difference in the Indian ocean...and bears no direct relation or connection

Dattaraj: On gong thunder activity is normal for the peninsula..please refer to the MW-1 and MW-2. It will help bring in moisture inland.

Rajesh sir
Is there any possibility of early onset of monsoon over west coast and mumbai owing to formation of low in Arabian sea.
Saeed

SVT said...

It seems more n more likely that pre monsoon low in Arabian sea will initially move north west but then tilt east towards Gujarat coast. That could bring heavy rains in Gujarat n Mumbai coast by 23th May. I know its Too early, need to keep eyes on it.

Rajesh, various weather models are showing low pressure ( core reaching 982) areas travelling down the west coast .. are we heading for heavy rains in north konkan gujarat...

rkjrdp said...

It seems low will form in SWBOB?

rajesh said...

Saeed Monsoon will be on schedule as given in Monsoon Watch...if chnges take place will inform .

Low pressure in Arabian Sea will strengthen ...maybe and travel NW as mentioned.

sset said...

repetition of 2014 Cyclone Nanauk over GUJ/MAHA ? Pune records 104mm of rain in just 2 hrs!! beating chennai which is desperately waiting for heavy rains defying forecasts...

SVT said...

Now it seems low will move west wards and then fizzle out in the sea.
