howers or thundershowers are expected to develop across several parts of Sri Lanka today, mainly during the afternoon and evening hours. According to the latest forecast issued at 2.00 p.m. on 03 May 2026, rainfall activity will affect the Western, Sabaragamuwa, Central, North-Western and Eastern provinces, as well as the districts of Polonnaruwa, Galle and Matara after 2.00 p.m.
Fairly heavy rainfall exceeding 50 mm is likely at some locations, particularly in the Western and Sabaragamuwa provinces and in the Galle and Matara districts. In addition, showers may occur during the morning hours in the coastal areas of the Southern province and in districts such as Kalutara, Colombo and Puttalam.
Misty conditions can be expected during the early morning hours in parts of the Central, Sabaragamuwa and Uva provinces and in the Ampara district, potentially reducing visibility for motorists.
The general public is advised to remain cautious and take necessary precautions to minimize damages caused by temporary localized strong winds and lightning during thundershowers.
