Only respite will be western disturbances in early May,no rains soon: weatherman The heat wave continued unabated on Wednesday,and temperatures even managed to climb into record books with the day clocking 43.5 degrees Celsius the hottest day so far in April in the last 10 years. At five degrees above normal,the India Meteorological Department (IMD) attributed the soaring temperatures to the hot winds coming in from western India. The department has some bad news too: these conditions will remain for the next two days at least. The director of IMD,B P Yadav said: Heat waves are created because of direct exposure to the sun and due to the advent of winds from regions warmer than Delhi. Todays temperatures have been pushed up by western winds. He also said this is natural for Delhi summers and that the mercury is not likely to go below 42 degrees in the next two days. The heat was back this week after a considerable dip in temperatures last weekend. The maximum temperature was cooler at 40.5 degrees last Wednesday,which had gone down further to 37 degrees by the time the week ended. However,come Monday,and the mercury had climbed back to 40 degrees and has been relentless since then. The weatherman predicts no rain in the near future. An officer on duty at the Safdarjung Meteorological Department said: This April was a very dry month. There wont be rains anytime soon. IMD officials said the whole of north India is in the grip of a heat wave particularly in parts of Saurashtra and Kutch and southern Rajasthan. The highest temperature of 46 degrees Celsius was recorded at Barmer in Rajasthan. The only respite in sight is the western disturbances expected to hit northwest India on May 2. Officials also said the hottest April 29 Delhi has seen was back in 1941,when the temperature had rocketed to 45.6 degrees Celsius.
