Delhi and its nearby areas are in for the strongest spell of rainfall so far this monsoon with the Meteorological Department issuing a red alert for Thursday.
“Generally cloudy sky with moderate rain and thunderstorms with isolated heavy to very heavy rain,” the Indian Meteorological Department said on Thursday.
Thunderstorm rain would occur over isolated places of south Delhi and adjoining areas. The weather office has predicted heavy rain in Rewari, Nuh, Hodal, Bawal, Manesar, Gurugram, Yamunanagar, Khatauli, Hastinapur and Faridabad on Thursday afternoon. Thunderstorm is also predicted to bring rains in Greater Noida, Noida, Aurangabad, Modinagar, Narora, Sahaswan, Muzaffarnagar, Shamli, Barsana, Jahangirabad, Siyana, Aligarh, Kurukshetra, Hapur and Meerut.
It would be one of the heaviest spells of the monsoon season so far in Delhi, Mahesh Palwat of Skymet Weather was quoted as saying by news agency PTI.
The MeT office issues colour-coded warnings to alert the public ahead of severe or hazardous weather which has the potential to cause “damage, widespread disruption or danger to life”.
A red alert is the strongest warning issued to officials directing them to take action, while an orange alert asks district officials to be prepared for a severe situation.
Heavy to very heavy showers on Thursday and Friday will lead to a significant decrease in temperatures and humidity levels.
“Monsoon is reviving in north India. On and off rains will continue in the Delhi-NCR region till Wednesday. The axis of monsoon trough, which at present runs south of Delhi, will shift northwards leading to fairly widespread rain and thundershower Wednesday onward,” Palawat said.
Delhi has recorded 156.5 mm rains from July 1 to July 23, which is four per cent more than the 30-year average of 149.8 mm, officials said. The city recorded 50.2 mm rainfall, the heaviest in the monsoon season this year, on July 22.
Overall, Delhi has received 167.7 mm precipitation against the long-term average of 215.3 mm since June 1, when the monsoon season starts, a deficiency of 22 per cent, according to the MeT data.
The IMD in a statement said widespread rain or thundershowers will occur over Himachal Pradesh, Uttarakhand, Punjab, Haryana, Chandigarh, Delhi and Uttar Pradesh from July 24 to 27. It has predicted one or two heavy spells on July 25 and 26.
