Due to a low-level atmospheric disturbance, thundershowers are expected to develop over the most parts of the island during today (Aug.21) and tomorrow (Aug. 22), says the Department of Meteorology.
Showers or thundershowers will occur at times in Central, Uva, Northern, North-central, Eastern and Sabaragamuwa provinces. Heavy showers above 100 mm and cloudy skies can be expected at some places in these areas.
Meanwhile, showers or thundershowers will occur elsewhere, particularly in the evening or night.
The Met. Department has urged the public to take adequate precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
