Showers or thundershowers are expected to occur at most places across Sri Lanka 
after 1.00 p.m. today, indicating widespread unstable atmospheric conditions over
the island. According to the Department of Meteorology Sri Lanka, heavy rainfall
exceeding 100 mm is likely at some locations, particularly in the Western, Sabaragamuwa,
Central and North-Western provinces, as well as in the Galle, Matara and Anuradhapura
districts. These conditions may lead to localized flooding and temporary disruptions.

Misty conditions can be expected during the early morning hours in parts of the 
Central, Sabaragamuwa, North-Central and Uva provinces, along with the Galle, Matara
and Kurunegala districts. Motorists are advised to exercise caution due to reduced
visibility.

The general public is strongly advised to take necessary precautions to minimize
damage caused by lightning, temporary strong winds and heavy downpours associated
with thundershowers.
