The Meteorology Department has said that the heat index, the temperature felt on the human body, is likely to increase up to ‘caution level’ today (21) in the Northern, North Central, North Western, Western, Southern, and Eastern Provinces, and in the Ratnapura and Monaragala districts.

As per the advisory by the Department, under this level of temperature, fatigue is possible with prolonged exposure and activity, while continued activity could result in heat cramps. Thus, the members of the public are advised to stay hydrated, take breaks in the shade as often as possible, and limit strenuous outdoor activities. They are also requested to check up on the elderly and the sick, never leave children unattended inside vehicles, and to wear lightweight and white or light-coloured clothing. The Heat Index Forecast is calculated by using relative humidity and maximum temperature and is the condition that is felt on the body. This is not the forecast of maximum temperature. It is generated by the Meteorology Department for the next day period and prepared by using global numerical weather prediction model data.
