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.

### Sea Conditions Around Sri Lanka

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

Fishermen and naval communities are advised to exercise caution, as temporarily 
strong gusty winds and very rough seas can occur during thundershowers.
