Rainy conditions over most parts of the country are expected to be enhanced due to low-level atmospheric disturbance in the South-east of Sri Lanka intensifying into a low-pressure area, the Meteorology Department said.
It said heavy showers above 100 mm can be expected at some places in Northern, North-Central Eastern, Sabaragamuwa and Southern Provinces.
Meanwhile, showers or thundershowers will occur at times in Eastern, Uva, Northern and North-Central Provinces and in Matale District.
Showers or thundershowers will occur elsewhere during the afternoon or night.
