Showers or thundershowers will occur at times in Western, Sabaragamuwa, Southern and North-western provinces and in Kandy and Nuwara-Eliya districts. Fairly heavy showers above 75 mm are likely at some places in Western and Sabaragamuwa provinces and in Galle and Matara districts.  Showers or thundershowers will occur at several places in Eastern, Uva and North-Central Provinces during the evening or night.

Fairly strong winds about (30-40) kmph can be expected at times over the Western slopes of the central hills and in the Northern, North-central and North-western provinces and in Hambantota district.

Winds will be south-westerly in the sea areas and wind speed will be (30-40) kmph.  Wind speed can increase up to (55–60) kmph at times in the sea areas off the coasts extending from Trincomalee to Puttalam via Kankasanthurai, Mannar and from Hambantota to Pottuvil and up to 50 kmph at times in the sea areas off the coasts extending from Puttalam to Hambantota via Colombo and Galle.

The sea areas off the coasts extending from Kankasanthurai to Puttalam via Mannar and from Hambantota to Pottuvil will be rough at times while the sea areas off the coasts extending from Puttalam to Hambantota via Colombo and Galle may be fairly rough at times.

The swell wave heights may increase (about 2.0m–2.5 m) in the sea areas off the coast extending from Kalpitiya to Hambantota via Colombo and Galle (this is not for land area).  Strong gusty winds and very rough seas can be expected during thundershowers.

The general public is kindly requested to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
