Heavy rain lashes Delhi, IMD issues red alert; waterlogging in several area

Delhi has been put on a 'red' alert after heavy rain lashed Delhi-NCR on Wednesday evening that caused waterlogging and traffic congestion in several areas.

A 'red' warning calls for action and vigilance.

The National Flash Flood Guidance Bulletin has included Delhi in its list of 'areas of concern', the weather office said.

Delhi Lt Governor, in a post on X, said he cautioned officers to remain alert in light of the heavy downpour in Delhi.

"Apart from ensuring minimum inconvenience to people in general, they are advised to specifically address issues at sites prone to waterlogging, including coaching centres," he said in the post.

Multiple areas, including Lutyen's Delhi, Kashmere Gate and Rajinder Nagar, among others, were inundated following the heavy rain.

The India Meteorological Department (IMD) has advised people to remain indoors, secure windows and doors and refrain from unnecessary travel.

"Seeking safe shelter and avoiding tree cover are recommended to mitigate risks. Stay tuned for further updates as the situation develops," it said in the advisory.

According to IMD's Automatic Weather Station (AWS) network, the Pragati Maidan observatory in central Delhi recorded 112.5 mm of rainfall in one hour.

An extreme amount of precipitation in a short period, specifically 100 mm of rainfall within an hour, is defined by the IMD as a "cloud burst".

There has, however, been no official statement on the situation from weather officials.

Widespread light to moderate rainfall is likely over Delhi during the next two hours, the IMD said in a nowcast.

Furthermore, thunderstorms with lightning and surface winds reaching speeds of 50 kilometres an hour are also likely at isolated places during this period, it added.

Visuals from south Delhi's Qutub Minar area showed vehicles wading through waterlogged roads while traffic police personnel tried to manage vehicular movement.

The traffic police have issued alerts about the routes affected and urged people to plan their journeys accordingly.

The national capital on Wednesday recorded a maximum temperature of 37.8 degrees Celsius.

On Tuesday, Delhi recorded its highest maximum temperature for the month this year, with the mercury settling at 39.3 degrees Celsius, five notches above normal.

According to the IMD, the humidity level stood at 63 per cent at 5:30 pm.

The city recorded a minimum temperature of 30.4 degrees Celsius, 3.3 notches above normal.

The IMD has predicted a wet spell till August 5.
