Showers or thundershowers will occur at times in Northern, Eastern, North-central and Uva provinces and in Hambantota district. Showers or thundershowers will occur elsewhere in the evening or night.
Heavy falls of about 100mm can be expected at some places in Central, Eastern, Uva, Sabaragamuwa and Southern provinces.

Misty conditions may occur at some places in Central, Sabaragamuwa and Western provinces during the morning.
There may be temporary localized strong winds during thundershowers.
