South-west monsoon is established over the island and therefore, showery and windy conditions are expected to enhance further particularly in the South-western part of the island.

The Meteorology Department says showers or thundershowers will occur at times in Western, Southern, Central, Sabaragamuwa and North-western province.

Heavy rainfall about 100-150 mm can be expected at some places particularly in Kaluthara, Rathnapura, Galle, Matara, Gampaha and Kegalle districts.

Showers or thundershowers may occur at several places elsewhere over the island.

Fairly strong gusty winds up to 50 kmph are also likely over the country, particularly in western slope of the central hilly areas and Northern, North-central and Uva province and in Puttalam, Ampara and Batticaloa districts and strong winds up to 60 kmph are also likely over the Jaffna district and Pottuvil area.

Winds will be South-westerly and speed will be 30-40 kmph in the sea areas around the island.

The sea area off the coast extending from Trincomalee to Mannar via Kankasanturai and sea areaoff the coast extending from Matara to Pottuvil via Hambanthota can be rough at times as the wind speed can increase up to 60 kmph.
