Sri Lanka is expected to experience unsettled weather conditions on 17 June, with several spells of showers forecast for the Western, Sabaragamuwa, and North-Western provinces. Rainfall is also expected in the districts of Galle, Matara, Kandy, and Nuwara Eliya as the southwest monsoon continues to influence weather patterns across the island.
According to the forecast, showers or thundershowers may occur at a few places in the Uva and Eastern provinces, as well as in the Mullaittivu district, particularly after 2.00 p.m. Residents in these areas should remain alert for sudden changes in weather conditions during the afternoon and evening hours.
Fairly strong winds with speeds of 30–40 kmph can be expected at times over the western slopes of the central hills, the Southern and North-Central provinces, and in the Trincomalee district. The public is advised to take necessary precautions to minimize damage caused by temporary localized strong winds and lightning associated with thundershowers.

Weather conditions at sea are expected to remain active during the next 24 hours. Showers or thundershowers will occur at several places in sea areas extending from Chilaw to Matara via Colombo and Galle.
South-westerly winds will prevail with speeds of 30–40 kmph. Wind speeds may increase to 50–60 kmph at times in the sea areas from Galle to Pottuvil via Hambantota. Winds may also reach up to 50 kmph in sea areas extending from Trincomalee to Galle via Kankasanthurai, Puttalam, and Colombo.
The sea areas from Galle to Pottuvil via Hambantota will be rough at times, while waters from Trincomalee to Galle via Kankasanthurai, Puttalam, and Colombo will be fairly rough. Wave heights may increase to around 2.0–2.5 meters in sea areas from Colombo to Pottuvil via Galle and Hambantota.
Fishermen and naval communities are advised to exercise caution, as temporarily strong gusty winds and very rough seas can occur during thundershowers.
