An intense storm with heavy early-morning rain hit the national capital on Friday, causing a house collapse that killed a woman and her three children and delaying more than 200 flights.

The city received 77 mm rain in just three hours during the downpour which started around 5 am.
Visuals from several areas showed uprooted trees and people stuck in waterlogged roads. Videos surfaced on social media which showed half-submerged vehicles wading though Minto Road.
Major Somnath Marg in RK Puram, Minto Road and Khanpur were particularly affected in the rain.
The India Meteorological Department (IMD) has issued a red alert, urging people to remain extremely vigilant and take necessary precautions.
Three children and a woman died after a a tree fell on their house following strong gusty winds that accompanied rains in the city, causing it to collapse.
"We received a call regarding a house collapse in Kharkari Nahar village in Najafgarh at 5.25 am. We deployed multiple teams on the spot and four people were rescued from the rubble," a Delhi Fire Services official said.
They were rushed to a nearby hospital where they were declared dead, he said.
The deceased have been identified as Jyoti (26) and her children --- Aryan (7), Rishabh (5) and Priyansh (7 months). Her husband Ajay (30) sustained minor injuries in his chest and wrist.

Delhi Chief Minister Rekha Gupta inspected waterlogged road stretch at Majnu Ka Tila area while PWD minister Parvesh Verma reached the Minto bridge area to take stock of the situation.
"Waterlogging continues to be a concern across various parts of Delhi due to choked drains and pothole-ridden roads. Officials have been instructed to immediately identify all such vulnerable spots in the city that are prone to waterlogging," she said.
The chief minister described the pre-monsoon showers as a "warning sign" for the city's infrastructure, calling it the result of a decade-long backlog in development.
"If Delhi doesn't see planned development, such management issues will continue to arise. But today, the entire administration is on its toes to address these challenges," she added.
The Aam Aadmi Party lashed out at the BJP government with senior leader and former Delhi CM Atishi posting videos of waterlogging in Dhaula Kuan and ITO on X.
"Is this what the people of Delhi expected from the 4-engine BJP Govt?" she posted on X, referring to the BJP governments at the Centre, in Delhi, the municipal corporation and the local MP.
