Heavy rains pounded the national capital on Thursday evening, resulting in water logging, traffic congestion and brief suspension of flight operations at the Delhi airport.
Hailstorm was also reported in some parts of Delhi, the weather office said.
The Regional Meteorological Centre of the IMD said there was a low pressure area over Haryana that resulted in heavy rains over the National Capital Region.
Mahesh Palawat, Vice-President (Meteorology and Climate Change), said there was a cyclonic circulation over Punjab and Haryana. High humidity coupled with temperatures that have been rising since the last two days led to the formation of clouds, a normal phenomenon in pre-monsoon and post-monsoon time.
According to the Meteorological Department, the maximum temperature recorded at 5.30 pm was 34.8 degrees Celsius, a notch above the normal, and the minimum was 23.8 degrees Celsius, two notches above the normal.
Humidity levels oscillated between 83 and 55 per cent.
