Tuesday, July 27: Delhi’s tryst with monsoon rains has been a volatile one, with extended periods of dry weather followed by brief intervals of very heavy rains. With the most delayed arrival of monsoon in 19 years, the national capital witnessed sweltering heatwaves in the first two weeks of July. Since the monsoon onset on July 13, repeated bouts of heavy rains have been disrupting the daily lives of Delhiites.
Over the last 24 hours till Tuesday morning, Delhi’s base station Safdarjung has received 100 mm rainfall. This is the first time in eight years that Delhi witnessed a three-digit daily rainfall figure in July. It was back on July 21, 2013, that Delhi had seen such heavy July rains. Meanwhile, extremely heavy rains of 215 mm were registered in Rajatan’s Chhabra.
Monday’s rains brought the Delhi- National Capital Regin (NCR) to a standstill with waterlogging and traffic jams, particularly in central and southern Delhi. While the rains brought relief from sultry weather conditions, parts of the city like Pragati Maidan and Mathura Road witnessed partially submerged vehicles wading through inundated intersections.

The Weather Channel met team highlights that a cyclonic circulation lies over Pakistan and adjoining areas, attracting westerly winds from the Arabian Sea. The system is likely to persist for the next five days. Moreover, the formation of a low-pressure over the Bay of Bengal is strengthening the easterly monsoon winds. Another couple of circulations lie over southeast Rajasthan and northwest Madhya Pradesh.
Given these meteorological conditions, the converge of westerly and easterly winds over west Uttar Pradesh is likely to lead to inclement weather over plans of north India during the next few days. Moderate rains with isolated heavy falls and thunderstorms are possible over Delhi on Tuesday and Wednesday. After a brief pause, similar conditions are likely to make a comeback on Saturday, July 31.
