Heavy Rain Floods Andheri Subway as IMD Issues Red Alert for Thane

On Wednesday, July 1, 2026, intense rainfall and a high tide caused widespread waterlogging across Mumbai, flooding the Andheri subway and prompting the India Meteorological Department (IMD) to issue Red alerts for neighbouring Thane, Palghar, and Raigad. The severe weather coincided with a major communication failure, as the Brihanmumbai Municipal Corporation (BMC) disaster management helpline became non-functional for several hours during the crisis.

The heavy downpours left Mumbai under an Orange alert on Wednesday as the region continued to experience relentless rain. Meteorological data revealed that the city has already accumulated more than 500 mm of rainfall over the current season. The eastern suburbs experienced particularly heavy precipitation, with local stations recording nearly 200 mm of rain in a single 36-hour period.

The combination of heavy rainfall and a high tide led to severe waterlogging in several low-lying areas. The Andheri subway was heavily flooded, which severely disrupted local movement and transport in the area.

As residents navigated the flooded streets and sought assistance, emergency coordination faced a major setback. The BMC disaster management helpline, which serves as a critical point of contact during weather emergencies, went completely offline. Municipal officials confirmed that the helpline remained non-functional for several hours on Wednesday due to a telecom connectivity issue with Mahanagar Telephone Nigam Limited (MTNL).

The weather threat is expected to extend well beyond Mumbai's city limits. While Mumbai remained under an Orange alert, the IMD issued Red alerts for the neighbouring districts of Thane, Palghar, and Raigad for different days later this week, indicating that the wider region must prepare for further extreme weather conditions.
