Mumbai is experiencing an unusually early and intense monsoon, with the southwest monsoon arriving on May 26, breaking a century-old record. The IMD has issued a red alert for the city and its neighboring districts, warning of very heavy to extremely heavy rainfall at isolated places. This early onset has led to severe flooding and significant disruptions across the region.
Record-Breaking Rainfall and Urban Vulnerability
In May 2025, Mumbai recorded 295 mm of rainfall, surpassing the previous record of 279.4 mm set in May 1918. The Colaba observatory reported 439 mm of rainfall, with major downpours causing severe waterlogging. The intense rainfall has overwhelmed the city’s drainage systems, leading to flooding in low-lying areas and highlighting the city’s vulnerability to extreme weather events.
Transport Disruptions and Public Inconvenience
The heavy rains have caused significant disruptions to Mumbai’s transport systems. Over 50 Central Railway services were cancelled, and Western Railway services also faced cancellations due to waterlogging at key stations. The flooding was worsened by a high tide, which led to early closure of floodgates and the failure of key pumping stations. Commuters reported frustration over packed trains and unclear announcements.
BMC’s Flood Management Strategies Under Review
The BMC’s flood management strategies are being reviewed as several flood-prone areas remain submerged. The reduction in dewatering pumps and incomplete desilting efforts have raised concerns about the effectiveness of the city’s flood management strategies. Despite assurances, new flooding in areas like Breach Candy has highlighted potential shortcomings in the newly completed infrastructure.
Public Safety Measures and Advisory
In response to the ongoing crisis, the BMC has declared a holiday for all schools and colleges in Mumbai. Authorities have advised residents to stay indoors and avoid unnecessary travel. The IMD has issued a red alert for heavy to very heavy rainfall at isolated places, with the possibility of strong winds. Residents are urged to remain vigilant and follow official advisories.
Conclusion
Mumbai’s unprecedented monsoon onset has led to severe flooding and significant disruptions across the city. The IMD’s red alert highlights the intensity of the situation, while the BMC’s preparedness and response strategies are under scrutiny. Residents are urged to stay informed and adhere to safety advisories to navigate the ongoing challenges posed by the heavy rains.
