The Department of Meteorology on Tuesday requested the general public to take adequate precautions to minimise damage, due to heavy rain and thunder storms being forecast. Wind could reach 50 kilometers per hour across the island. The western slope of the central hills as well as the Southern province along with the North Western and the Western provinces are said to be affected by this condition. The sea areas extending from Galle to Potuvil via Hambantota and Matara will be faced with roughness during the coming hours.
