 "Squall, dust storm lash Delhi; rail, air, metro operations hit")
A squall and dust storm with a wind speed of up to 109 kmph barrelled through Delhi and neighbouring areas today, affecting flight, rail and metro operations, uprooting trees, and leading to incidents of wall collapse.
The sky turned dark grey around 4:30 pm. Gusty winds and rain lashed the national capital, causing the temperature to drop around 10 notches.
The much-needed reprieve came after a sweltering day, when the maximum temperature had reached 40.60 degrees Celsius, a notch above the normal. Humidity during the morning hours was recorded at 60 per cent, a MeT official said.
The strong winds knocked down a number of trees in the city.
Four incidents of wall collapse were reported from Najafgarh, Transit Camp, Nehru Place, Mohan Garden in Uttam Nagar and Raj Nagar in Palam, said a senior officer from the Delhi Fire Service.
Operations at the Delhi airport came to a halt due to the dust storm.
