On Wednesday, the India Meteorological Department (IMD) said monsoon is likely to reach the national capital three to four days earlier than the usual date of June 27.
Kuldeep Srivastava, the head of the regional forecasting centre of the IMD, said a cyclonic circulation over West Bengal and the neighborhood will move towards southwest Uttar Pradesh by June 19 and June 20.
"It will help in further advancement of the monsoon in western Uttar Pradesh, some parts of Uttarakhand, northeast Rajasthan and eastern Haryana between June 22 and June 24," he said.
This means the wind system will reach the national capital by June 22-23, which is three to four days earlier, he said.
The IMD has predicted normal rainfall (103 per cent) for northwest India this year.
