Showers or thundershowers will occur at several places over most provinces particularly after 2.00 pm today, the Department of Meteorology said.
It added few showers are likely in the Eastern and Southern coastal areas.
Fairly heavy falls (above 50mm) are also likely at some places particularly in the Central, Sabaragamuwa and Uva Provinces.
“There may be temporary localized strong winds during thundershowers. General public is kindly requested to take adequate precautions to minimize damages caused by lightning activity,” it concluded.
