The Meteorology Department says showers or thundershowers will occur at several places over most parts of the island during the afternoon or night.
Heavy showers of about 100 mm can be expected at some places in Western, Sabaragamuwa, Central, Southern and North-western provinces.
Showers may occur in Southern province and in Batticaloa and Ampara districts during the morning too.
The general public is kindly requested to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
