The Department of Meteorology says the rainy condition is expected to enhance over the island as the effect of the low-pressure area in the Southwest Bay of Bengal Sea area still persists to the North of Sri Lanka.
Showers or thundershowers will occur at times over Northern, North-central and North-Western provinces.
Showers or thundershowers will occur at several places elsewhere after 2.00 p.m.
Fairly heavy falls of about 100mm can be expected at some places in the Northern Province.
Fairly strong gusty winds about 50kmph can be expected over Northern Province.
Misty conditions may occur at some places in the Central, Sabaragamuwa and Western provinces during the morning.
There may be temporary localized strong winds during thundershowers.
