The national capital received intermittent light to moderate rains this morning, bringing down respite from the heat. Several parts of the city, including central Delhi, however, have been receiving rainfall since last night.
Road traffic was affected for a few minutes at Dhaula Kuan, DND Flyover, AIIMS, Nigambodh Ghat due to ankle-deep water. Stretches around Pitampura and Kamla Nagar also witnessed traffic jams due to waterlogging.
Parts of the city have been receiving light rainfall since Saturday. The city received 1.4 mm rainfall from 8.30 am to 5.30 pm yesterday.
The increased rainfall have helped Delhi residents breathe some clean air, with the national capital recording between good and satisfactory categories for the past one week, making it one of the longest spells of clean air in the national capital this year, authorities said.
According to the Centre-run System of Air Quality and Weather Forecasting (SAFAR), the overall air quality index (AQI) of Delhi was 44 on Friday which falls in good category, while the Central Pollution Control Board (CPCB) said the AQI was recorded in satisfactory category at 59.
An AQI between 0 and 50 is considered ''good'', 51 and 100 ''satisfactory'', 101 and 200 ''moderate'', 201 and 300 ''poor'', 301 and 400 ''very poor'', and 401 and 500 ''severe''.
The level of PM2.5 (particles in the air with a diameter of less than 2.5 micrometre) was recorded at 44 and the PM10 level was recorded at 21 on Friday, SAFAR said.
The AQI was recorded at 69 on Tuesday, 63 on Wednesday and 75 on Thursday.
"Overall air quality of Delhi is in good category. Wide spread rain helped to the sudden improvement of the air quality. Increased rain fall activity is likely in association with approaching western disturbance and monsoon low, fairly widespread to widespread rainfall and isolated heavy rain falls are expecting over the weekend," it added.
According to the CPCB, PM2.5 levels in the national capital dropped by 7.3 per cent in 2018 when compared to 2017 and by 14.8 per cent over 2016.
Similarly reduction in PM10 levels in 2018 is 8.6 per cent over 2017 and 16.5 per cent over 2016.
Delhi and its adjoining areas are likely to receive moderate rains for next few days with minimum and maximum temperatures hovering around 25 degree Celsius and 34 degree Celsius, stated India Meteorological Department in its weather forecast bulletin.
The relative humidity in these regions is likely to oscillate between 87 per cent to 92 per cent for the next few days.
