New Delhi, May 19 -- After Saturday's 70kmph gusts felled trees, damaged infrastructure and razed a building, Delhi enjoyed relative calm on Sunday. The India Meteorological Department (IMD) logged a maximum of 41.4 degrees Celsius (degC), surface winds of 15-20kmph and no rainfall up to 5.30pm, despite a yellow alert that lasted most of the day. A fresh advisory removes colour-coded alerts from Monday, though IMD predicts "isolated spells of light rain and winds up to 50kmph," conditions that will cap daytime temperatures and stave off heat-wave thresholds until at least May 24. Air quality also benefited. With the Capital remaining in the "moderate" band for a second straight day, the Commission for Air Quality Management revoked Stage I restrictions of the Graded Response Action Plan. Mahesh Palawat, vice-president, Skymet Meteorology, attributed the respite to successive western disturbances. "We have seen western disturbances approach northwest India in May, one after another, as a cyclonic circulation," he said. "At present, a cyclonic circulation and a trough will both persist over the northern plains this coming week, with a possibility of rain and gusty winds to continue." He added: "There will be enough moisture in the atmosphere this coming week. Therefore, thunderclouds will develop mostly during late afternoon and evening, leading to dust storm, thunderstorms and light rain." IMD expects Monday's high to ease to 38-40degC; Sunday's minimum was 26.9degC, near normal. In Gurugram, meanwhile, the thermometer reached 41.5degC, with a low of 23.8degC on Sunday....
