The forecast, issued at 4:00 p.m. today by the Forecasting Division of the National Meteorological Centre, advises the public to take necessary precautions against lightning and temporary localized strong winds.
General Weather Outlook for the Next 36 Hours
According to the latest advisory, residents in the Uva, Central, and Eastern provinces, as well as those in the Polonnaruwa and Mullaittivu districts, can expect showers or thundershowers to occur at several places after 2:00 p.m. Notably, fairly heavy falls exceeding 50 mm are likely at some locations within the Uva and Eastern provinces, urging residents in these areas to remain vigilant.
Furthermore, a few showers are anticipated in the Western, Sabaragamuwa, and North-western provinces, alongside the Galle and Matara districts. While these regions may experience less intense rainfall, the possibility of isolated showers remains.
Public Safety Advisory
The DMC has issued a crucial appeal to the general public to take adequate precautions to minimize potential damage caused by temporary localized strong winds and lightning, which are often associated with thundershowers. These natural phenomena can pose significant risks, and preparedness is key to ensuring safety.
Sun Overhead Phenomenon
Adding an interesting astronomical detail, the DMC also highlighted that the sun is positioned directly over the latitudes of Sri Lanka between August 28th and September 7th, due to its apparent southward relative motion.
