The heat wave in Delhi and the Northwest is expected to subside by tomorrow, according to the National Weather Service.

 Over Delhi, Himachal Pradesh, Punjab, Haryana-Chandigarh, and Punjab-Haryana, the weather office predicts partly overcast skies with the probability of thunder development in isolated areas.

The India Meteorological Department (IMD) announced today that the heatwave in Delhi and neighbouring portions of northwest and central India is expected to subside from Monday.

From tomorrow, the weather office predicts partly overcast skies with the probability of thunder in isolated areas over Delhi, Himachal Pradesh, Punjab, Haryana-Chandigarh, east Rajasthan, and parts of Uttar Pradesh, providing some relief from the sweltering heat.

From May 3, the heatwave across Madhya Pradesh, Chhattisgarh, Telangana, and West Rajasthan will subside, according to the IMD.

For the past two weeks, India has been suffering from a severe heat wave. Northwest and central India had their hottest April in 122 years, with average high temperatures of 35.9 degrees Celsius and 37.78 degrees Celsius, respectively, due to a lack of rain.

The previous record for the northwest region was 35.4 degrees Celsius set in April 2010, while the previous record for the central region was 37.75 degrees Celsius set in 1973.

Scientists have warned that the early arrival of a severe summer is linked to climate change, putting more than a billion people in the region at danger of heat-related consequences.
