The city’s temperature fell by 11 degrees Celsius, from 29 degrees to 18 degrees on Monday morning, the India Meteorological Department said.
The weather office has predicted Delhi will continue to record winds with speeds of 50 to 80 kmph on Monday. However, hotter temperatures are expected later, reaching 39 degrees Celsius.
“Dust storm/thunderstorm with light to moderate intensity rain and gusty winds with speed of 50-80 km/h very likely to continue over Delhi-NCR and adjoining areas during next two hours,” the India Meteorological Department said in a tweet.
Delhi and its satellite cities had been scorching under a heatwave until last week with at least two weather stations recording temperatures above 49 degrees Celsius.
While the rains and winds brought down the temperature, the downpour caused waterlogging in several parts of the city as scores of trees were uprooted on the roads, causing traffic jams during the morning rush hour.
At least three incidents of walls collapsing were reported from different parts of the city, though without any casualties.
The early morning thunderstorm also affected air traffic, with at least 60 flights either delayed for arrival or departure. Two flights were cancelled.
The Delhi International Airport requested passengers to get “updated flight information” before heading to the airport as flights were affected.
The weather office has predicted widespread rainfall and isolated thunderstorms in Delhi’s neighbouring states of Punjab, Haryana, Uttarakhand and Jammu and Kashmir over the next two days.
The western Rajasthan state, which had a blistering summer and acute water shortages, can expect “peak rainfall intensity” on Monday.
Mahesh Palawat, vice president of private weather forecaster Skymet Weather, said that the city recorded its coldest May temperature in the last decade, on Monday.
“The city recorded the minimum temperature during the decade. While rain has stopped and the weather system is clearing up, we are anticipating another spell of rain and thunderstorm activity tonight and tomorrow,” Mr Palawat told The National.
The South Asian nation has sweltered this year in the highest temperatures in almost 125 years.
Large parts of northern, western and central India recorded spells of hot weather in March and April as the mercury significantly breached the average monthly temperature.
But the south-west monsoon, when the country receives about 75 per cent of its rainfall, advanced early this year.
India’s southern and eastern regions are already recording heavy rainfall due to the onset of the south-west monsoon. Weather experts say the monsoon will touch the northern region by June 1.
