Weather conditions across Sri Lanka are expected to become more favorable for afternoon
thundershowers as the country approaches October. Atmospheric conditions are gradually
becoming supportive of increased thunderstorm activity over most parts of the island
from October 1.

For Wednesday, September 30, showers or thundershowers may occur at several places
in the Uva, Eastern and Central provinces, as well as in the Polonnaruwa and Mullaittivu
districts after 1.00 p.m. Fairly heavy rainfall exceeding 50 mm is possible at some
locations in these areas. Residents in affected regions should remain alert to sudden
changes in weather during the afternoon and evening.

A few showers may also occur during the morning in coastal areas of the Western 
Province and in the Galle and Matara districts. Meanwhile, misty conditions are 
expected at some places in the Sabaragamuwa and Central provinces during the early
morning hours.

The public is advised to take adequate precautions during thundershowers, as temporary
localized strong winds and lightning may occur.
