**SEA AREA FORECAST**

In the sea areas around Sri Lanka, showers or thundershowers are expected at several
locations during the next 24 hours. Southwesterly winds will prevail at speeds of
25 to 35 kmph. Wind speeds may occasionally increase to 45–50 kmph in sea areas 
extending from Chilaw to Kankasanthurai via Puttalam.

These sea areas may become fairly rough at times, while other sea areas around the
island are expected to remain slight. In addition, wave heights may increase to

Temporarily strong gusty winds of 60–70 kmph and very rough seas can be expected

activities are advised to exercise caution, particularly in areas affected by thunderstorms.

The public is encouraged to monitor official weather updates and take appropriate
precautions as rainy conditions continue across the island.
