Most parts of the city got sharp spells of rain on Sunday.

The afternoon showers led to waterlogging on MG Road and in Jorasanko, Wood Street, Kasba and some other parts.

The conditions were largely overcast across the city throughout the day.

Around 1.30pm, Kasba and Park Circus were in the middle of a sharp spell of rain. Most parts of central Calcutta also got drenched.

Around 2pm, when chief minister Mamata Banerjee inaugurated the Rathyatra procession — organised by Iskcon — on Albert Road, the rain was almost blinding and had stalled traffic in Minto Park and adjoining areas.

But areas like New Alipore and Behala were almost dry at the same time.

A Met official called the rain “passing showers”.

The monsoon currents over Bengal are likely to become weaker. The volume of rain across the state is likely to dip on Monday and Tuesday, said the Met official.

“The monsoon trough was passing through north Bengal for the past few days. It is descending now. On Sunday, it was passing through East Midnapore. By Monday, the trough is expected to descend further. As a result, states like Odisha and Andhra Pradesh will get more rain in the coming days, until the trough rises again,” said H.R. Biswas, head of the weather section at the Regional Meteorological Centre, Calcutta.

June ended with a near-50 per cent rain deficit in Calcutta. But July has been reasonably rainy. July is usually the rainiest month in Calcutta. The average rainfall quota of the month is just under 400mm.

From July 1 to 7, the city has got around 58mm of rain, compared to 92mm that it should have, said a Met official.

“The monsoon trough at mean sea level now passes through Bikaner, Sikar, Gwalior, Sidhi, Daltonganj, Contai.... to northeast Bay of Bengal and extends upto 0.9km above mean sea level,” said a Met report.

“Yesterday’s cyclonic circulation over west-central Bay of Bengal off south Andhra Pradesh coast persists,” it added.
