While water level has receded in almost all parts of Mumbai, National Disaster Relief Force (NDRF) teams have been kept on standby in different parts of the city in view of heavy rainfalls predicted by the meteorological department. NDRF teams are kept on standby in Kurla, Parel and Andheri, said an official on Thursday.

However, according to reports, around 30 flights were cancelled and another 118 delayed today, with the cancellation of 14 incoming and 16 outbound flights. This follows a statement by the Mumbai Airport Authority Limited (MIAL) earlier that had said that all operations were 'normal'.

From 8.30 AM to 8:30 PM on Wednesday, 217.4 millimetres of rain was recorded. It was the second-highest rainfall of this season, when the first rain occurred on July 1, recording 375 mm of rainfall.

The Met department has declared an orange alert for Thursday, which is likely to bring in the maximum rainfall. A green alert has been declared for Friday, with light rains expected. 

In view of the Met Department announcement, the schools and colleges have been discharged. 

According to an earlier update, 20 flights were evacuated due to the incessant rainfall, while 300 were delayed. Meanwhile, Chief Public Relations Officer (PRO) of Western Railway also announced that three trains - Surat - Mumbai Central, Mumbai Central-Surat and Bandra T -VAPI - were cancelled due to heavy rains and water-logging at Nallasopara.

As incessant rains lashed Mumbai and Maharashtra, life was thrown out of gear with delay in train and flight services causing great inconvenience to passengers.

Several passengers were seen sleeping outside the Mumbai Domestic Airport amid the flight delays due to rainfall.

"Passenger Alert!! Due to heavy rains, flights out of Mumbai will be delayed. Passengers are requested to check flight status through Air India website, Mobile App or Customer care," Air India tweeted on Wednesday.
