Sea areas:

The deep depression over southeast Bay of Bengal remained as a deep depression and laid centered at 11.30 p.m. on May 10 near 10.80N and 88.20E.

It is very likely to move north-northwestwards and intensify into a cyclonic storm over southeast Bay of Bengal and then into a severe cyclonic storm over central Bay of Bengal.

The 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.

Further, they are 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, Kankesanthurai and Mullaitivu.

The Meteorology Department also advised the naval and fishing communities to be attentive to future forecasts issued in this regard.
