Showers or thundershowers may occur at a few places in Uva, Eastern and North-Central provinces in the evening or night.

The general public has been requested to take adequate precautions to minimize damages caused by lightning activity and localized strong winds during thundershowers.
Showers or thundershowers will occur at several places in the sea areas around the island.
Winds will be South-westerly in direction in the sea areas around the island. Wind speed will be (30-40) kmph. Wind speed can increase up to (50-55) kmph at times in the sea areas extending from Matara to Batticaloa via Hambantota and Pottuvil and from Chilaw to Kankesanturai via Puttalam and Mannar.
The sea areas extending from Matara to Batticaloa via Hambantota and Pottuvil and from Chilaw to Kankesanturai via Puttalam and Mannar can be rough at times. The other sea areas around the island can be fairly rough at times.
There is a possibility that nearshore sea areas off the coast extending from Kalutara to Pottuvil via Galle, Matara and Hambantota, may experience surges due to the effect of swell waves, having 2.0 – 2.5 m height (This is not for land areas).
Naval and fishing communities and those who are living in coastal areas are also requested to be vigilant in this regard.
