Sri Lanka will continue to experience unsettled weather on 25 September as the influence
of the deep depression over the Bay of Bengal gradually weakens.The system has weakened
into a depression and moved inland across India. Its direct impact on Sri Lanka 
is expected to gradually decrease from tomorrow, although several areas may still
experience heavy rain, strong winds and thundershowers.

Showers or thundershowers are expected to occur at times in the Western, Sabaragamuwa,
Southern, Central and North-Western provinces. Heavy rainfall of around 100 mm is
possible at some locations in these areas. Residents and motorists are advised to
remain alert during periods of intense rainfall, particularly where temporary strong
winds and lightning accompany thunderstorms.

Fairly strong winds of around 30–40 kmph may occur at times over the western slopes
of the Central Hills, as well as in the North-Central and North-Western provinces.
Trincomalee, Hambantota and Matale districts may also experience these stronger 
winds. The public is advised to take adequate precautions to minimize possible damage
from localized strong winds and lightning during thundershowers.

**Sea Areas Around Sri Lanka**

The deep depression that was previously over the Bay of Bengal has moved inland 
over India after crossing the coast of northern Andhra Pradesh and southern Odisha.
Although its influence on Sri Lanka is expected to weaken, hazardous marine conditions
will continue over several sea areas.

Heavy thundershowers are expected over the west-central Bay of Bengal, where winds
may occasionally increase to 70–80 kmph. Sea conditions in these areas are expected
to become very rough. Naval and fishing communities are advised not to venture into
the sea areas between 10°N and 22°N latitude and 82°E and 90°E longitude until further
notice. Those already operating in the affected areas are advised to move away and
remain attentive to further forecasts and bulletins issued by the Department of 
Meteorology.

Around Sri Lanka, showers or thundershowers will occur at times in the sea areas
extending from Kankasanthurai to Hambantota via Puttalam, Colombo and Galle. Showers
or thundershowers may also develop in several other sea areas during the evening
or night.

South-westerly winds will prevail, with speeds of 30–40 kmph. Wind speeds may increase
to 55–65 kmph at times in the sea areas extending from Trincomalee to Negombo via
Kankasanthurai, Mannar and Puttalam, and from Galle to Pottuvil via Hambantota. 
Winds may also reach 50–55 kmph in the sea areas from Negombo to Galle via Beruwala.

The sea areas from Trincomalee to Negombo and from Galle to Pottuvil may become 
very rough at times, while the sea areas from Negombo to Galle via Beruwala will
be rough. Wave heights may reach around 2.0–2.5 metres from Puttalam to Pottuvil
via Colombo, Galle and Matara. Temporary strong gusty winds and very rough seas 
may occur during thundershowers.
