When Does IMD Declare a Heatwave?
According to IMD guidelines, a heatwave is declared when the maximum temperature of a station reaches at least 40°C or more in plains, 37°C or more in coastal areas and 30°C or more in hilly regions. Another method IMD deploys to determine a heatwave for any region is to check if the departure from the normal maximum temperature is 5 degrees Celsius or more.
Further. if a region’s actual maximum temperature remains 45 degrees Celsius or more, IMD considers it a heatwave, irrespective of the normal maximum temperature.
The criteria for a heatwave has to be met in two meteorological subdivisions for at least two consecutive days, the IMD explained.
Residents are advised to stay informed through IMD updates and take necessary precautions to stay safe during these extreme weather conditions.
