At Bhira in Raigadh, the temperature mapping centre recorded a high of 46.5 degrees Celsius for the 24 hours ending at 8 am today, but IMD officials said they would like to verify the findings.
"When the temperature (at Bhira) was reported to be 46.5 degree Celsius, we realised that something is wrong as no other place nearby recorded so high a temperature," S G Kamble, divisional In charge of Regional Meteorological Department, Colaba in Mumbai, said.
"Bhira village is located in the Sahyadri mountains and is close to a dam. The mountains are covered with forest. The height of the mountains around Bhira would be minimum 2,000 feet. In such a situation, if the mapping centre shows 46.5 degree, it should be doubted," he said.
Those doing the temperature mapping at Bhira are not the employees of IMD but trained by it, he said. A team of IMD officials will now verify the findings.
With Bhira doubtful, an IMD official said that Akola was, according to them, the hottest place in the country today. Wardha, Nagpur and Chandrapur recorded 43 degree Celsius.
Unlike Bhira, there were no doubts in Uttar Pradesh where heat-wave like conditions prevailed over most parts with the mercury crossing 40 degree Celsius in Varanasi, Allahabad, Hamirpur and Agra.
The Met office said Varanasi and Agra were the hottest place in the state recorded 41.4 degrees, followed by Hamirpur at 41.2 deg C. It predicted hot weather conditions in various parts of the state in the next 24 hours.
The onset of Heat wave conditions very likely to prevail at many places over West Madhya Pradesh, few places over East Madhya Pradesh and at isolated places over Chhattisgarh.
