The national capital reeled under sultry weather on Wednesday with rains playing truant for most part of the day.
The city, however, received rainfall at isolated places towards the evening, leading to a marginal drop in the mercury.
The weatherman has predicted heavy to very heavy rain in some parts of Delhi on Thursday and Friday, which will reduce the rain deficit in the national capital.
Vice president meteorology and climate change, Skymet Weather, Mahesh Palawat said rains are expected to intensify on Thursday night as the axis of monsoon trough is moving towards the north and moisture-laden winds are rushing in from the Arabian Sea and the Bay of Bengal.
Delhi has recorded 156.5 mm rains from July 1 to July 24, which is four per cent more than the 30-year average of 156.4 mm, officials said.
Overall, it has received 167.7 mm precipitation against the long-term average of 221.9 mm since June 1, when the monsoon season starts, a deficiency of 24 per cent, according to India Meteorological Department data.
