Several spells of showers will occur in Northern and North-Central provinces and in Trincomalee district.

Sea areas:

The cyclonic storm “Mocha” over the Southwest Bay of Bengal has intensified into a severe cyclonic storm and laid centered near 12.7°N and 88.1°E at 11.30 p.m. yesterday (May 11).

It is very likely to move northwards and gradually intensify into a very severe cyclonic storm during next six hours over the central Bay of Bengal.

Thereafter, it is likely to recurve gradually and move north-northeastwards with further intensification. The system is likely to cross southeast Bangladesh and north Myanmar coasts around noon on May 14 (Sunday).

Naval and multi-day fishing communities are advised not to venture into the sea areas bounded by 03N - 20N and between 85E - 100E until further notice.

They are further requested to be vigilant while engaging in naval and fishing activities in the sea areas off the coast extending from Galle to Pottuvil via Matara and Hambantota and in the sea areas off the coast extending from Chilaw to Trincomalee via Puttalam, Mannar, Kankasanthurai and Mullaitivu.

Naval and fishing communities are also requested to be attentive to future forecasts issued by the Department of Meteorology in this regard.
