Calcutta went back to being hot and humid on Friday after heavy showers on the evening of Independence Day. The weekend, however, is likely to be rainy again.
The Alipore weather office recorded 81.2mm of rainfall on Thursday evening — the second-rainiest day this month after 84.6mm on August 7.
“The rain spoiled our Independence Day plans. It started pouring just as we were planning to go over to a friend’s place for a get-together. We were delayed by more than an hour as we had to wait for the rain to subside,” said Manisha Parekh, 28, of Kasba.
Gokul Chandra Debnath, the director of India Meteorological Department, Calcutta, attributed Thursday’s rainfall to “moisture incursion by the monsoon trough”. “The showers were localised and south Calcutta received more rain than the north,” he said.
Friday was a dry day with a low-pressure area forming in the northwest Bay of Bengal near the Andhra Pradesh-Odisha coast and pulling the monsoon trough away from Bengal.
The temperature dropped a notch to 32.7 degrees but the weather remained sultry with humidity ranging from 65 to 100 per cent.
The mercury is likely to stay put at around 33 degrees on Saturday before descending by a degree on Sunday when heavy rainfall is expected. “The low-pressure system is expected to move towards the Bengal coast. It will rain again on Saturday, get heavier on Sunday and continue for a couple of days more,” Debnath said.
The average total rainfall in Calcutta in August — traditionally the second rainiest month of year after July — is 352.4mm. But this year it has already received 286.4mm of rain in the first 15 days, a surplus of 57 per cent.
