Southwest monsoon to hit Kerala on May 30

Advance of southwest monsoon over the Andaman Sea normally takes place around  May 20 with a standard deviation of about one week. 

 

"During the last few days, enhanced convection and increased rainfall activity has been observed over the Bay of Bengal and the Andaman Sea.  The cross equatorial flow is likely to strengthen and deepen over the area. As such, conditions are becoming favourable for advance of southwest monsoon over the Andaman Sea and adjoining sea areas during the next 3-4 days. Past data suggests absence of any one to one association of the date of monsoon advance over Andaman Sea with the date of monsoon onset over Kerala or that with the seasonal monsoon rainfall over the country," a government statement said.
