Weather forecast issued at 05.30 a.m. on 06 May 2024 by the Department of Meteorology

Misty conditions can be expected at some places in Central and Sabaragamuwa provinces during the morning.

A few showers may occur over the coastal areas of Puttalam to Galle via Colombo during the morning while showers or thundershowers will occur at several places in Western, Sabaragamuwa, North-western, North-central and Central provinces and in Mannar, Vavuniya, Mullaitivu, Galle and Matara districts after 2.00 p.m.

Winds will be southwesterly or variable and wind speed will be (20-30)kmph. Wind speed may increase up to (40-45) kmph at times in the sea areas off the coasts extending from Puttalam to Kankasanthurai via Mannar and from Batticaloa to Hambanthota via Pottuvil.

The sea areas off the coasts extending from Puttalam to Kankasanthurai via Mannar and from Batticaloa to Hambanthota via Pottuvil can be fairly rough at times. Strong gusty winds and very rough seas can be expected during thundershowers.

The swell waves (about 2.0 m – 2.5 m) height and wave period (about 14s-16s) may increase in the sea areas off the coast extending from Kalpitiya to Pottuvil via Colombo, Galle, and Hambantota. Therefore, there is a possibility that near shore sea areas off the coast extending from Colombo to Matara via Galle, may experience surges due to swell waves.

General public is kindly requested to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers
