Large parts of Northwest India, especially Rajasthan, are likely to experience severe heatwave conditions till May 19, the India Meteorological Department (IMD) said Wednesday.
IMD has also forecast severe heatwave conditions over East and West Rajasthan and Uttar Pradesh till Friday. Heatwave conditions are also expected to continue over Western Madhya Pradesh till May 17 and over Haryana, Chandigarh and Delhi between May 17 and 19.
Central India is also expected to witness another heatwave. Chhattisgarh, Telangana, and parts of Vidarbha, Central Maharashtra and Marathwada are likely to remain under heatwave conditions till May 19, while Saurashtra and Kutch in Gujarat may continue to experience extreme heat till Thursday.
“There will be a gradual rise in the maximum temperatures by 4 to 6 degrees Celsius and will remain between 46-48 degrees Celsius till May 19,” the Met department said.
“An upper air cyclonic circulation prevails over Northwest Uttar Pradesh and Southwest Madhya Pradesh, both of which are leading to air subsidence over the region. The warm air accumulated during the daytime is thus remaining trapped, making the nights warmer than usual,” an IMD official said.
On Tuesday, Barmer in West Rajasthan recorded 48.3 degree Celsius, making it the hottest place in the country. The city’s highest-ever May temperature — 49.9 degrees Celsius — was recorded on May 27, 2024.
