Bracing for the impact of what is being billed as the most severe cyclone to hit Mumbai, the Central Railway (CR) rescheduled special trains and many airlines also cancelled their Mumbai operations.

The CR has rescheduled, diverted and regulated some trains on Wednesday, an official said. These include five special trains departing from Mumbai. Three special trains will be either divetred or regulated enroute, he added.

An alert has been issued for Mumbai city and suburbs, Thane, Palghar, Raigad, Ratnagiri and Sindhudurg districts.

Mumbai hasn't "experienced a serious cyclone landfall since 1891", according to Adam Sobel, professor of atmospheric science at Columbia University.

Mumbai experienced severe floods in 2005, and more recently in 2017 and 2019, but none of them were due to cyclones.
