Sri Lanka warned of thundershowers, gusty winds

ECONOMYNEXT – Thundershowers and heavy rainfall over 100 milimetres can be expected starting this afternoon or at night for the next 36 hours in the Western and Sabaragamuwa provinces and in the Kandy, Nuwara-Eliya, Galle and Matara districts, the meteorology department said Friday (09) afternoon.

Thundershowers are expected in several parts of Sri Lanka’s Western, Central, Sabaragamuwa, North Western and Southern provinces and a few places in the Eastern and Uva provinces in the evening or at night.

A few showers will occur in the North-Central Province.

Strong gusty winds up to 60kmph are likely to occur in the western slope of the central hills and gusty winds up to 50 kmph are likely in the Northern, North-Central, North Western and Southern provinces, the Trincomalee district and western coastal areas.

Strong gusty winds are likely over deep and shallow sea areas surrounding the island due to active southwest monsoon conditions, the Met department said.

Over the next 24 sea areas extending from Mannar to Pottuvil via Puttalam, Galle and Hambantota will be rough, the department said. Other sea areas can be fairly rough at times, it added.

“Fishermen are informed that it is dangerous to venture out to sea areas extending from Mannar to Pottuvil via Puttalam, Galle and Hambantota. Fishing and naval communities are requested to be vigilant in this regard.”

Winds will be south-westerly in the seas around the island at a speed of 30-40kmph. Speeds can increase up to 60-70kmph in the sea area extending from the mentioned area, the department said.

Rainfall amount (mm) is measured according to the following range:

Light 00-12.50
Light to moderate: 12.50-25
Moderate: 25-50

Fairly Heavy rain: 50 -100
Heavy rain: 100 – 150
Very heavy rain: 150 or more (Colombo/Jul09/2021)
