Showers may occur in Western and Sabaragamuwa provinces and in Galle and Matara districts, says the Meteorology Department.
Showers or thundershowers will occur at several places in Central, Uva, Eastern and North-Central provinces during the evening or night.
Mainly fair weather will prevail elsewhere, it said.
General public is kindly requested to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
