The Department of Meteorology issued an advisory for heavy rain across nine districts, effective for the next 48 hours.
Heavy rain will likely persist in the Western, Sabaragamuwa, and North-Western provinces, as well as Galle and Matara districts, the Department said.
According to the advisory, the showery conditions in the southwestern part of Sri Lanka are expected to intensify over the next few days due to an atmospheric disturbance in the vicinity of the island.
Showers or thundershowers are predicted at times in the Western, Sabaragamuwa, Southern, and North-Western provinces, with some areas expected to experience heavy rainfall exceeding 100mm.
Elsewhere in the country, showers or thundershowers will occur during the evening or night, with the possibility of fairly heavy showers exceeding 75mm in some areas.
The public were advised to take precautions against damaged caused by strong localized winds and lightning during thundershowers. (Newswire)
