**Sri Lanka Weather Forecast for 14 September 2026**

Sri Lanka is expected to experience widespread unsettled weather on 14 September,
with showers or thundershowers likely at several places across most parts of the
island after 1.00 p.m. The afternoon and evening period is expected to bring increased
rainfall activity, with some areas receiving particularly heavy rainfall.

Heavy falls exceeding 100 mm are likely at some places in the North-Central, Central,
Sabaragamuwa, Uva and North-Western provinces. Residents in these areas should remain
alert to changing weather conditions, especially during periods of intense rainfall.
Showers are also expected in the Western Province and in the Galle and Matara districts
during the morning hours.

The public is advised to take adequate precautions during thundershowers, as temporary
localized strong winds and lightning may occur. People are encouraged to remain 
cautious in exposed areas and avoid unnecessary outdoor activities during active
thunderstorms.
