Sri Lanka is expected to experience unsettled weather conditions on 11 June 2026,
with showers, thundershowers, and strong winds affecting many parts of the island.
According to the latest forecast, showers or thundershowers will occur at times 
in the Western, Sabaragamuwa, and North-Western provinces, as well as in the districts
of Galle, Matara, Kandy, and Nuwara Eliya.

Fairly heavy rainfall exceeding 50 mm is likely at some locations in these areas.
Residents are advised to remain vigilant, particularly in low-lying and flood-prone
regions, where intense rainfall could lead to localized water accumulation.

Strong winds will continue to influence weather conditions across the country. Wind
speeds of 40–50 kmph are expected at times over the western slopes of the central
hills, the Northern and North-Central provinces, and the districts of Hambantota
and Trincomalee. Other parts of the island can expect fairly strong winds ranging
between 30–40 kmph.

The Department of Meteorology urges the public to take necessary precautions against
temporary localized strong winds and lightning associated with thundershowers. Outdoor
activities should be planned carefully, and people are advised to seek safe shelter
during thunderstorms.

### **Sea Conditions and Marine Advisory**

Weather conditions at sea remain hazardous, particularly for fishing and naval operations.
Showers or thundershowers are expected at times in the sea areas extending from 
Chilaw to Hambantota via Colombo and Galle.

South-westerly winds will prevail with speeds of 30–40 kmph. However, wind speeds
may increase significantly up to 60–70 kmph in sea areas from Kankasanthurai to 
Kalpitiya via Mannar. Winds may also reach 50–60 kmph in sea areas extending from
Trincomalee to Kankasanthurai via Mullaittivu and from Kalpitiya to Pottuvil via
Colombo, Galle, and Hambantota.

The sea areas from Kankasanthurai to Kalpitiya via Mannar will be very rough at 
times. Fishing and naval communities are strongly advised not to venture into these
waters until further notice. Other surrounding sea areas will be rough to fairly
rough, with wave heights expected to increase to around 2.0–2.5 meters in waters
from Mannar to Pottuvil via Colombo, Galle, and Hambantota.

Mariners should remain alert, as temporarily strong gusty winds and very rough seas
can occur during thundershowers.
