The Department of Meteorology has warned residents across several districts to prepare for elevated heat conditions, with the heat index expected to reach cautionary levels during daytime hours.

The Department of Meteorology has issued a warm weather advisory affecting multiple regions across Sri Lanka's Eastern province and several central districts including Kilinochchi, Mullaitivu, Vavuniya, Polonnaruwa, and Monaragala. During daytime hours, residents in these areas should expect the heat index—a measure combining temperature and humidity to reflect how heat feels on the human body—to reach what the department classifies as the 'Caution Level' at certain locations.

According to the Department of Meteorology, the heat index calculation takes into account both relative humidity and maximum temperature readings to determine the actual conditions experienced by people in affected areas. The advisory highlights the potential health risks associated with such conditions, noting that extended sun exposure and outdoor physical activity can cause fatigue among residents. The department warned that continued exertion in such heat may result in heat cramps and other heat-related illnesses.

To mitigate these risks, the Department of Meteorology has advised residents in the affected districts to maintain adequate hydration levels and reduce strenuous outdoor activities during peak heat hours. The advisory serves as a precautionary measure to help communities prepare for and safely navigate the elevated temperatures expected in these regions.
