NEW DELHI: Delhi is likely to witness heavy to very heavy rainfall on Thursday and Friday which will lead to a significant decrease in temperatures and humidity levels.
It would be one of the heaviest spells of the monsoon season so far in Delhi, Mahesh Palwat of private weather forecaster Skymet Weather 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.
Overall, it 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 India Meteorological Department (IMD) data.

"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," Mr Palawat said.
