The Department of Meteorology has announced that the Heat Index — the temperature felt on the human body — is expected to rise to the ‘Caution level’ tomorrow (21) in the Northern, North-Central, North-Western, Western, Southern, and Eastern provinces, as well as in the Ratnapura and Monaragala districts.
According to the advisory, under this level of heat, fatigue is possible with prolonged exposure and physical activity, while continued activity could lead to heat cramps.
The public is therefore advised to stay hydrated, take frequent breaks in the shade, and limit strenuous outdoor activities. People are also urged to check on the elderly and the sick, never leave children unattended inside vehicles, and wear lightweight, white or light-colored clothing.
The Heat Index Forecast is calculated using relative humidity and maximum temperature to represent the condition felt on the body. It is not a forecast of the maximum temperature. The forecast is generated by the Department of Meteorology for the following day, using data from global numerical weather prediction models.
