Its the first spell of rains in Delhi since June 17, Mahesh Palwat of Skymet Weather, a private weather forecaster, said. In June, the national capital recorded just 11.4 mm of rainfall against the 30-year average of around 55 mm, Kuldeep Srivastava, senior scientist at IMD, said. Rainfall in July will be marginally lower than the normal. Overall, it will be a normal monsoon. Normally, 60 cm of rain is recorded from June 1 to September 30 in Delhi, he said. Neighbouring areas of Gurgaon, Faridabad and Noida received good rainfall Thursday. Conditions are favourable for monsoon to make an onset in the national capital in the next 48 hours, Palawat said. Normally, the wind system reaches the city on June 29. Intermittent light rains are expected till July 10. Heavy showers are likely after that, he said. Palawat said the onset of monsoon at a particular place in north India is determined by strong easterly winds, high humidity and good rainfall in neighbouring areas.
