“Heavy to very heavy rainfall with isolated extremely heavy rain is very likely to continue over Sub-Himalayan West Bengal, Sikkim and Northeast India during next 4-5 days,” it said.

Heatwave to severe heat wave conditions are likely to continue over northern parts of India for another four to five days, the IMD has warned.

“Monsoon is expected to remain weak for the next 3-4 days. Once it picks up, it may move to West Bengal, Jharkhand etc., but then move over to the Himalayan foothills before making an onset over Delhi, Haryana and neighbouring areas around month end,” said Mahesh Palawat, vice president, climate and meteorologist at Skymet Weather.

“The westerly winds are very strong. They are not letting moist easterly winds penetrate over northwestern states. Monsoon onset will not happen here until wind direction changes,” added Palawat.

On Thursday, the Safdarjung Observatory, the city’s official weather station, recorded a maximum temperature of 44.8 degrees Celsius, 4.9 degrees above normal.

The rainfall deficiency since June 1 increased from 1% on Wednesday to 9% on Friday. There is a 9% deficiency over the country, with 57% rainfall deficiency over northwest India, 30% over east and northeast India, 9% deficiency over central India and 50% excess over Peninsular India, according to the IMD.

HT reported on June 13 that the progress of the monsoon is likely to weaken over the next week and consequently intensify heatwave conditions over northwest and eastern India, meteorologists said.
