The deep depression over the Bay of Bengal has weakened into a depression after moving inland over India, crossing the coast of northern Andhra Pradesh and southern Odisha.

The Meteorology Department said the impact of the system on Sri Lanka’s weather is expected to gradually decrease from today.

Showers or thundershowers will occur at times in the Western, Sabaragamuwa, Southern, Central and North-western provinces, with fairly heavy rainfall exceeding 100 mm possible in some areas.

Fairly strong winds of around 30–40 kmph are expected at times over the western slopes of the Central Hills, North Central and North Western provinces, as well as in Trincomalee, Hambantota and Matale districts.

The public has been advised to take adequate precautions against temporary localized strong winds and lightning during thundershowers.

Meanwhile, heavy thundershowers are expected over the western central and adjoining northwestern Bay of Bengal, where winds could occasionally increase to 70–80 kmph, resulting in very rough seas.

The Meteorology Department has warned naval and fishing communities not to venture into sea areas between 10°N and 22°N latitude and 82°E and 90°E longitude until further notice.

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 occur in several other sea areas during the evening or night.

Southwesterly winds of 30–40 kmph are expected, with speeds increasing up to 55–65 kmph at times in sea areas from Trincomalee to Negombo and from Galle to Pottuvil via Hambantota.

Sea conditions in these areas are expected to be very rough at times, while seas from Negombo to Galle via Beruwala may become rough.

Wave heights could increase to around 2.0–2.5 metres in sea areas extending from Puttalam to Pottuvil via Colombo, Galle and Matara.

Temporarily strong gusty winds and very rough seas may occur during thundershowers.
