Showers or thundershowers will occur over most places of the island in the evening or night, says the Department of Meteorology.

Heavy falls above 100 mm are likely at some places in Sabaragamuwa, Uva and Southern provinces and in Kalutara, Nuwara-Eliya and Polonnaruwa districts.

Showers or thundershowers are likely over coastal areas of Western and Southern provinces and in Puttalam, Mannar and Jaffna districts during the morning too.

The general public is requested to take adequate precautions to minimize damages caused by lightning activity and localized strong winds during thundershowers.

Sea areas:

The low-pressure area developed over the south Andaman Sea and adjoining southeast Bay of Bengal sea area persists over the same region further. Fishing and naval community are requested to be vigilant in this regard in the deep sea area.

Showers or thundershowers will occur at several places in the sea area extending from Mannar to Batticaloa via Colombo, Galle and Hambantota. Showers or thundershowers may occur at a few places in the sea area extending from Mullaitivu to Trincomalee.

Winds will be South-westerly in the sea area extending from Mannar to Batticaloa via Colombo, Galle and Hambantota and winds will be South-easterly in the other sea areas around the island. Wind speed will be (25-35) kmph.

Wind speed can increase up to (40-45) kmph at times in the sea areas extending from Galle to Batticaloa via Hambantota.

The sea area extending from Galle to Batticaloa via Hambantota can be fairly rough at times. The other sea area around the island can be moderately rough.  

Temporarily strong gusty winds (up to 70-80 kmph) and rough seas can be expected during thundershowers.
