The continuous rain, which started late Sunday night, not only affected flights but also resulted in waterlogging in and around the airport.
The heavy downpour threw movement of vehicles in several parts of Kolkata out of gear. Gusty winds uprooted trees
and damaged lamp posts in several areas, disrupting electricity supply.
The civic administration officials said water was taking time to recede because of the high tide at River Hooghly during the rains.
Rainfall was the result of a cyclonic trough extending from MP,Chhattisgarh and West Bengal to Bangladesh.
