ECONOMYNEXT – Sri Lanka’s meteorology department expects heat felt on the human body to go up to ‘extreme caution levels’ (amber) in Polonnaruwa, Trincomalee, Batticaloa, Ampara, Monaragala and Hambantota districts tomorrow (April 03).
The rest of the island, with the exception of the central province, may experience ‘caution’ (yellow) level heat on the heat index, the met department said.
The heat index forecast is calculated using relative humidity and maximum temperature, which translates to the sensation of heat felt by the body. This is not a forecast of maximum temperature, a med department official explained.
This year is better than last year, the official said, as in 2020 a heat advisory had to be issued as early as February. The met department issued a heat advisory for the first time this year over the past two days.
Explaining the reasons for the ongoing heat wave and high humidity, the official said it could be due to the sun’s position directly over Sri Lanka, as well as calmer winds experienced during the monsoon as well and the evening monsoon rains.
The met department advises the public to stay hydrated and take regular breaks in the shade, at outdoor job sites. Those indoors are advised to check up on the elderly and the sick and to not leave children unattended.
The public is also advised to limit strenuous outdoor activities, find shade and stay hydrated. Lightweight and light coloured clothing is recommended, the department added. (Colombo/Apr02/2021)
