Showers or thundershowers are expected to occur at most places across Sri Lanka 
after 1.00 p.m. today, bringing widespread rainfall to many parts of the island.
According to the Department of Meteorology Sri Lanka, fairly heavy rainfall exceeding
75 mm is likely at some locations, particularly in the Western, Sabaragamuwa, Central
and North-Central provinces, as well as in the districts of Kurunegala, Galle and
Matara.

Misty conditions are also expected during the early morning hours in several areas,
including the Western, Central, Sabaragamuwa and Uva provinces, along with Galle
and Matara districts. These conditions may reduce visibility, and motorists are 
advised to exercise caution when traveling in the early hours.

The general public is strongly advised to take necessary precautions to minimize
potential damages caused by temporary localized strong winds and lightning during
thundershowers. Sudden weather changes may occur, especially during the afternoon
and evening periods.
