Kolkata: Life was thrown out of gear in most parts of the metropolis on Saturday, following torrential rain that led to waterlogging in low-lying areas and snapped road links at several places.
The city received 186.1 mm rainfall in the past 24 hours till around noon on Saturday, the Regional Meteorological Centre here said.
The Met office has forecast heavy rain for the day.
Commuters were seen wading through knee-deep waters in key thoroughfares, including Central Avenue, College Street, Shakespeare Sarani and Behala.
Vehicular traffic was disrupted in several areas of central, south and north Kolkata, resulting in traffic snarls.
Flight operations were also affected due to rain, as take-off and landing was delayed, said a senior official of the Netaji Subhas Chandra Bose International Airport.
Eastern Railway CPRO Nikhil K Chakraborty said circular railway services were cancelled from 10.40 am onwards, due to waterlogging.
Train movement in Sealdah and Howrah sections of the Eastern Railway was slow, but there has been no cancellation so far, Chakraborty said.
In the southern states, Kerala received downpour since Tuesday night and many low lying areas were waterlogged. The toll in the rain-battered state had gone up to 95. A red alert was sounded for three north Kerala districts of Malappuram, Kannur and Kozhikode, which bore the brunt of the flood fury and landslides last week.
On the other hand, increase in rainfall has significantly affected the air quality in Delhi which has been oscillating between good and satisfactory categories for the past one week, making it one of the longest spells of clean air in the national capital this year, authorities said on Friday.
The authorities have attributed increased rainfall with approaching western disturbance as the main reason behind the improvement in air quality.
The AQI was recorded at 69 on Tuesday, 63 on Wednesday and 75 on Thursday.
Officials said it is the longest spell of clean air experienced by Delhiites this year.
