The Department of Meteorology has warned residents across several districts to prepare for elevated heat conditions, with the heat index expected to reach caution levels in parts of the Eastern and North-Central provinces.

The Department of Meteorology has issued a warm weather advisory affecting residents in the Eastern and North-Central provinces, as well as the Kilinochchi, Mullaitivu, Vavuniya, and Monaragala districts. The alert indicates that the heat index—a measurement reflecting how hot conditions feel to the human body rather than the actual air temperature—is expected to reach caution levels in some areas tomorrow.

According to the Met Department, the heat index is calculated by combining relative humidity and maximum temperature readings to determine the actual physiological impact of weather conditions on people. The department cautioned that extended sun exposure and outdoor physical activity during these periods can result in fatigue and heat-related complications. In particular, continued exertion in hot conditions may lead to heat cramps and other heat-related illnesses.

In response to the forecast, authorities have issued guidance for residents to minimize health risks. The department has recommended that people maintain adequate hydration levels and reduce or postpone strenuous outdoor activities during the period of elevated temperatures. These precautions are intended to help residents avoid heat-related medical emergencies during the advisory period.
