Showers or thundershowers will occur over most parts of the island during the evening or night, says the Department of Meteorology.
Heavy rainfall above 100 mm can be expected at some places in Sabaragamuwa, Central, Western, Uva and North-western provinces and in Galle and Matara districts.
The general public is urged to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
