Mumbai, India’s financial hub, was brought to a standstill on Monday after relentless rainfall flooded roads, delayed flights, and forced schools to shut down.

According to the India Meteorological Department, several parts of the city received more than 140 millimetres (5 inches) of rain since Monday morning. The downpour left vehicles stranded on waterlogged streets, causing massive traffic congestion. Authorities urged residents to stay indoors where possible.

Late Sunday night, three people were injured when the staircase of a two-storey building collapsed in the city’s southern district, highlighting the dangers of crumbling infrastructure during the monsoon season.

Officials issued a red alert for Mumbai and surrounding districts, warning of continued heavy rainfall through Tuesday. The alert prompted citywide school closures to ensure student safety.

Flight operations were also hit. NDTV reported that at least nine incoming aircraft were forced to abort landings due to poor conditions, though it remains unclear if they were later diverted.

Mumbai’s crisis comes amid torrential rains lashing India’s Himalayan states in recent weeks, where dozens have died and villages have been submerged. The situation has raised concerns about the growing intensity of the monsoon season and its impact on infrastructure and communities across the country.

Authorities in Mumbai remain on high alert as the city braces for another day of heavy rain.
