Heatwave is a condition of air temperature that becomes fatal to the human body when exposed. It is defined based on the temperature thresholds over a region in terms of actual temperature or its departure from normal.
In certain countries, it is defined in terms of the heat index based on temperature and humidity or based on the extreme percentile of the temperatures.
The heat wave is considered if the maximum temperature of a station reaches at least 40 degrees Celsius or more for plains and at least 30 degrees Celsius or more for Hilly regions.
IMD has advised people to avoid heat exposure, wear lightweight, light colour, loose, cotton clothes, cover heads, and use a cloth, hat or umbrella.
