While the continuous rain caused water-logging in several parts of the city, the downpour intensified in the evening as the storm lashed the eastern metropolis, felling trees and branches which blocked important thoroughfares.
One person was reported to be killed after he was crushed by a tree in the city's Jadavpur area.
"The city recorded 24.2 mm rainfall in the last 24 hours and witnessed a storm with a speed of 70 km an hour at 7.05 p.m.," the met office said.
"With the well marked low pressure concentrating into a depression over Bay of Bengal, heavy rains are likely to continue," it said.
Commuters, including people returning from offices, faced the brunt of the rain and storm as many of the areas got choked.
Trains services were also disrupted in the Sealdah South division with trees falling on an overhead wire.
"Train service was disrupted due to falling of trees on the overhead cable at Sonarpur area in the Sealdah South division. The rescue work is in progress and the service will resume soon," said an Eastern Railway spokesperson.
