The Meteorology Department says showers or thundershowers will occur at several places over most parts of the country during the afternoon or night.
Fairly heavy showers about 75mm are likely at some places in Central, Sabaragamuwa and Western provinces and in Galle and Matara districts.
General public is kindly requested to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
Showers or thundershowers will occur at a few places in the sea areas off the coast extending from Mannar to Matara via Puttalam, Colombo and Galle and in the sea areas off the coast extending from Pottuvil to Trincomalee via Batticaloa.
Winds will be south-easterly to south-westerly and wind speed will be 20-30 kmph.
The sea areas around the island will be slight.
