The Meteorology Department says several spells of showers will occur in Western and Sabaragamuwa provinces and in Kandy, Nuwara-Eliya, Galle and Matara districts.
A few showers may occur in North-Western province, it said.
Showers or thundershowers may occur at a few places in Uva province and in Ampara and Batticaloa districts during the evening or night.
Mainly fair weather will prevail elsewhere over the Island.
Fairly strong winds of about 40 kmph can be expected at times in western slopes of the central hills, Northern and North-Central provinces, and in Monaragala, Hambantota and Trincomalee districts.
General public is kindly requested to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
