ECONOMYNEXT – Showers or thundershowers will intensify in the Western, Sabaragamuwa, Central, Southern Northern provinces in the coming days, according to the Department of Meteorology.
The Western and Southern provinces will likely experience thundershowers particularly in the morning hours, the Met Department said.
Heavy rainfall up to 100mm can be expected in parts of the Western, Central, Sabaragamuwa and Uva provinces and in the Galle and Matara districts.
Sea areas extending from Mannar to Pottuvil via Colombo, Galle and Hambantota too will receive showers or thunderstorms.
The Met Department said the sea is expected to be rough in the areas extending from Puttalam to Pottuvil via Colombo, Galle and Hambantot with other areas are expected to be moderate.
The department added that there is a possibility of surges due to swell waves having 2.0- 2.5m height near the shore mainly off the coast from Puttalam to Hambanthota via Colombo and Galle.
A storm surge is the abnormal rise in sea water during a storm, measured as the height of the water above the normal predicted astronomical tide. The surge is caused primarily by a storm’s winds pushing water onshore.
Temporarily strong gusty winds and rough seas can be expected during thundershowers, the department said.
Wind patterns in general will be south-westerly in the sea areas extending from Kankasanturai to Pottuvil via Mannar, Colombo, Galle and Hambantota.
In other sea areas around the island winds will be North-easterly or variable in direction, the Met Department said.
Wind speed will be 20-30kmph and can increase up to 40-45kmph in the sea area extending from Galle to Pottuvil via Hambantota and from Puttalam to Kankasanturai via Mannar. (Colombo/Apr30/2021)
