The downpour has impacted air travel, with IndiGo and other airlines cautioning passengers about expected delays and advising them to confirm their flight schedules before heading to the airport. Access roads to Chhatrapati Shivaji Maharaj International Airport have been severely waterlogged, affecting smooth connectivity. Mumbai Traffic Police have enforced diversions as major subways and underpasses, including the Andheri subway, remain submerged and unusable. This has resulted in long traffic snarls across several important corridors. Authorities have repeatedly urged residents to avoid vulnerable locations, especially coastlines, and to contact emergency helplines during any critical situations arising from the heavy rainfall.

In view of the Red alert issued by IMD across Mumbai city and suburbs, citizens are requested to avoid visiting coastal and low-lying areas.

Our officials and staff are alert and ready to assist Mumbaikars. Dial 100 / 112 / 103 in case of any emergency.#MumbaiRainAlert…
