Heavy showers above 100 mm can be expected at some places in the aforementioned areas.
Showers or thundershowers will occur at a few places in the Eastern and Uva provinces in the evening or night.
The Met. Department urges the general public to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
Fairly strong winds up to (40-50) kmph can be expected in the Northern, North-central and North-western provinces as well as in Hambantota and Trincomalee districts.

Showers or thundershowers will occur at times in the sea areas extending from Mannar to Hambantota via Colombo and Galle. Heavy falls are likely at some places. Showers or thundershowers may occur at several places in the other sea areas around the island.
