Rains To Advance Rapidly Into Indian West Coast By May End

MAY 15, 2016

EARLY MONSOONS

Rainfall activity is going to increase dramatically on India's west coast by the end of May, 2016.

Call it monsoon rains or pre-monsoon rains. We leave the technicality to the met department. But monsoon winds are going to advance rapidly up the west coast in the next 15 days. 

Knocking on the doors of Mumbai in 15 days.

How will this happen?

Firstly the present Bay of Bengal low pressure off the Tamil Nadu coast is going to push the rains into Kerala, Tamil Nadu, Karnataka, Andhra Pradesh. Perhaps right into the Indian northeast, Myanmar and Bangladesh.

So 91B is going to engine the monsoons into southern and eastern India. Or create favourable conditions for its onset.

Next the Arabian Sea branch will become active. Though it is uncertain if a storm system will develop or not, clusters of rain systems are expected to advance from southwest Arabian Sea into the Malabar coast. This is according to NOAA's GFS model forecast.

See the rainfall map below. It shows the expected accumulated precipitation by May 31, 2016. We see the Indian coast drenched with more than 25 inches of rain by month end. The yellow colors on the map.
