The Department of Meteorology has issued a warm weather advisory for the Eastern Province and the districts of Jaffna, Kilinochchi, Mullaitivu, Vavuniya and Monaragala.
According to the advisory, the heat index — the temperature felt by the human body — is expected to reach the ‘Caution Level’ in parts of these areas during the daytime tomorrow (18).
The Met Department said the heat index forecast is calculated using the maximum temperature and relative humidity, reflecting how hot conditions are likely to feel.
It warned that prolonged exposure to the sun and outdoor activities could result in fatigue, while continued physical activity may lead to heat cramps.
Residents in the affected areas have been advised to stay well hydrated and avoid strenuous outdoor activities during the hottest parts of the day.
