COLOMBO, Sri Lanka – 04 September 2026 – The Department of Meteorology (DMC) has issued its latest 36-hour weather forecast for Sri Lanka, advising residents to prepare for widespread showers and thunderstorms across several provinces. The forecast, released at 4:00 p.m. on September 4, 2026, highlights potential heavy rainfall and warns the public about associated risks.
General Weather Outlook for the Next 36 Hours
According to the Forecasting Division of the National Meteorological Centre, showers or thundershowers are anticipated at various locations in the Uva, Central, and Eastern provinces, as well as in the Polonnaruwa and Mullaittivu districts, particularly after 2:00 p.m. tomorrow, September 5th. There is a strong likelihood of fairly heavy falls exceeding 75 mm in some of these areas, which could lead to localized impacts.
Furthermore, several spells of showers are expected to occur in the Western and Sabaragamuwa provinces, including the districts of Galle and Matara. Residents in these regions should be prepared for intermittent rainfall throughout the forecast period.
Public Safety Advisory
The DMC has issued a crucial advisory to the general public, urging everyone to take adequate precautions to minimize potential damage caused by temporary localized strong winds and lightning during thundershowers. Such weather phenomena can pose significant risks, and preparedness is key to ensuring safety.
Solar Movement: Sun Directly Overhead
An interesting celestial event is also underway, as the sun is positioned directly over the latitudes of Sri Lanka between August 28 and September 7, a result of its apparent southward relative motion. Tomorrow, September 5th, at approximately 12:08 noon, the sun will be directly overhead in several specific locations. These include Moratuwa, Kesbewa, Polgasowita, Handapangoda, Sri Palabaddala, Bogawanthalawa, Idalgashinna, Yudhaganawa, Kotiyagala, and Panama. This phenomenon often brings higher temperatures and intense sunlight to these areas.
