According to Met department, in large areas, a heatwave is declared when the mercury touches the 45 degrees Celsius mark for two days in a row and a severe heatwave is when the temperature soars to 47 degrees Celsius for two consecutive days. However, in small areas, like the national capital, a heatwave is declared if the maximum temperature is recorded at 45 degrees Celsius even for a day.

Delhi has been experiencing a heatwave for a week now and the condition is likely to be so on Tuesday as well with the IMD predicting the highest temperature of 46 degrees Celsius.

Even a week ago, 11 of the 15 hottest places in the world were in India. Meanwhile, heatwave-like conditions are likely to prevail over Rajasthan, MP and Vidarbha as well.

After a delay of a week, the monsoon hit the Kerala coast on Saturday, marking the official commencement of the four-month rainfall season in the country. “Monsoon has made an onset over Kerala today (June 8),” said IMD’s Director General-designate Mrutyunjay Mohapatra.
