New Delhi: A tormenting heatwave swept through the national capital and its neighbouring areas on Sunday with the mercury leaping to 49.2 degrees Celsius at Mungeshpur in northwest Delhi and 49.1 degrees Celsius at Najafgarh in the southwest parts of the city. Maximum temperatures reached unbearable highs of 48.4 degrees Celsius at Sports Complex, 47.5 degrees Celsius at Jafarpur, 47.3 degrees Celsius at Pitampura and 47.2 degrees Celsius at Ridge.

At the Safdarjung Observatory, Delhi’s base station, the maximum temperature rose to 45.6 degrees Celsius, five notches above the normal and the highest this year so far. The primary weather station had recorded a maximum temperature of 44.2 degrees Celsius on Saturday and 42.5 degrees Celsius on Friday. The city saw the maximum temperatures rise to 46.8 degrees Celsius at Ayanagar, 46.4 degrees Celsius at Palam and 45.8 degrees Celsius at Lodhi Road.

All the weather stations recorded a heatwave day. The neighbouring Gurgaon recorded a scalding temperature of 48.1 degrees Celsius, the highest since May 10th, 1966, when the city logged 49 degrees Celsius. Weather forecasters said a cyclonic circulation over Punjab and Haryana will induce pre-monsoon activity that will provide some relief from the intense heat on Monday and Tuesday. The IMD said a thunderstorm or a dust storm is likely in the national capital on Monday.

Delhi received a minuscule 0.3 mm of rainfall in April against a monthly average of 12.2 mm. March saw no rainfall against a normal of 15.9 mm. The IMD had predicted above-normal temperatures in May.
