The maximum temperature in the national capital on Sunday is expected to hover around 45 degrees Celsius, the Met department said. It added that the relative humidity in the national capital recorded at 8:30 am on Sunday was at 40 per cent. This is the fifth heatwave in the capital this summer.
Madhya Pradesh will continue to reel under severe heatwave conditions for the next 2-3 days but with decreased intensity.
In Uttar Pradesh, the heatwave will continue on Sunday and Monday. On Saturday too, parts of the eastern Uttar Pradesh recorded 48.8 degrees Celcius temperature, while Rajasthan breached 48 degrees. Most parts of northwest India, including Punjab, Haryana, Rajasthan, and Madhya Pradesh had experienced heatwave to severe heatwave conditions on Saturday.
Meanwhile, the western disturbance is likely to affect northwest India. As a result, there will be a significant decrease in the temperatures after 24 hours, which will eventually decrease the condition of a severe heatwave in northwest India, specifically, Punjab, Haryana, and Rajasthan, Kumar said. The clouds are observed in some parts of Jammu and Kashmir from today, itself, he added.
