Heatwave returns to pockets in central, northwest India; IMD predicts heavy rainfall in THESE states
A heatwave is declared when the maximum temperature is over 40 degrees Celsius and at least 4.5 notches above normal.
Unlike earlier predictions by the India Meteorological Department (IMD), several parts of the country witnessed heatwave conditions on Friday with mercury breaching 45 degrees Celsius mark in northern parts of west Rajasthan and eastern Vidarbha and in some parts of Bundelkhand region. Chandrapur in Maharashtra`s eastern Vidarbha area recorded the highest maximum temperature at 46.4 degrees Celsius. Other parts of India, including Delhi-NCR, Vidarbha, Rajasthan, and Madhya Pradesh also recorded temperatures above 44-45 degrees Celsius.
Earlier, in the last week of May, the Met Office had at least twice forecasted that there would be no heatwave conditions in the country. Even the May 31 bulletin of IMD had said, "No heatwave conditions likely over the country during the next five days."
The weather department in its forecast, however, mentioned a "gradual rise in maximum temperatures by 2-3 degrees Celsius very likely over most parts of northwest and central India during next three days and no significant change thereafter".
A heatwave is declared when the maximum temperature is over 40 degrees Celsius and at least 4.5 notches above normal. A severe heatwave is declared if the departure from normal temperature is more than 6.4 notches, according to the IMD. Based on absolute recorded temperatures, a heatwave is declared when an area logs a maximum temperature of 45 degrees Celsius. A severe heatwave is declared if the maximum temperature crosses the 47-degree Celsius mark.
Temperature rising since June 1
"The temperature has been increasing since June 1 but the heat wave is restricted to a very limited area - only some districts such as Ganganagar in Rajasthan, Bundelkhand area in Uttar Pradesh, Allahabad, south-east UP and east Vidarbha," IMD scientist R.K. Jenamani said.
"There is no Western Disturbance and the westerly wind is dominating that brings heat from the Pakistan side. Pakistan is also experiencing 45-46 degrees Celsius temperatures," he said. The current spell of heatwave is likely to be till June 5-6.
