The Department of Meteorology has issued a weather advisory, requesting the naval and fishing communities to be vigilant of the sudden roughness in the Southern Sea areas.
According to the department, the possibility for heavy showers or thundershowers and sudden roughness, associated with a sudden increase of wind speed (up to 70- 80 kmph) in the above given sea areas, is high due to the active cloudiness in the Southern Sea areas.

Several spells of showers will occur in Ampara and Batticaloa districts.

There may be temporary localized strong winds during thundershowers. The general public is requested to take adequate precautions to minimize damages caused by lightning activity.
Showers or thundershowers at times will occur in the sea area off the coast extending from Galle to Hambantota. Heavy showers can be expected at some places too, the Department of Meteorology stated.
