- Why is Mumbai flooding despite heavy rains being normal in June?
The Indian Meteorological Department (IMD) has confirmed that Mumbai received 300 millimeters of rain in 24 hours on June 24, 2026, triggering severe flooding that has disrupted road and rail traffic, according to multiple verified reports. The downpour—nearly double the city’s average monthly rainfall—has led to wall collapses, uprooted trees, and at least one car crushed in low-lying areas, officials and local media report.
The IMD’s Mumbai office, which monitors monsoon progress, described the rainfall as "exceptionally heavy" for this phase of the southwest monsoon, which officially advanced into the region on June 10. Authorities have attributed the intensity to a low-pressure system over the Arabian Sea, which has intensified the monsoon’s usual activity.
Why is Mumbai flooding despite heavy rains being normal in June?
The city’s drainage system, built in the 19th century, cannot handle 200 mm of rain in a single night—a threshold Mumbai exceeded on June 23, as confirmed by the Mumbai Metropolitan Region Development Authority (MMRDA). "The stormwater drains are clogged with debris, and the city’s elevation gradient is too shallow to prevent waterlogging in residential zones," said an MMRDA spokesperson. The 300 mm figure—reported by the IMD and cross-verified by Rediff and NDTV—marks the highest 24-hour rainfall in Mumbai since 2017, when 299 mm triggered a similar crisis.
How are schools, trains, and daily life affected?
All schools and colleges in Mumbai remain closed on June 24, with the state education department extending the shutdown until further notice, per The Telegraph India. The Central Railway has suspended services on the Western Line between Bandra and Andheri due to submerged tracks, while the Harbour Line faces delays of up to two hours, according to Indian Railways’ official updates. The Brihanmumbai Municipal Corporation (BMC) has deployed 1,200 workers to clear debris from drains, though officials warn that further heavy rain is expected through June 25.
What’s the government doing to prevent worse flooding?
The Maharashtra government has activated its State Disaster Response Force (SDRF) to assist the BMC, while the National Disaster Management Authority (NDMA) has issued an advisory urging residents in low-lying areas to relocate temporarily. The IMD has forecast "scattered to widespread rainfall" across Mumbai and its suburbs through June 26, with isolated areas possibly receiving 150–200 mm more. "We are monitoring the situation closely and coordinating with the Army for additional support if needed," said a senior official from the state’s Home Department.

What happens next?
Residents are advised to avoid travel unless essential, as localized flooding is expected to persist until drainage systems are cleared. The IMD’s next update, scheduled for 11:30 AM IST on June 24, will determine if the orange alert (indicating heavy rainfall) is extended beyond June 25. The BMC has opened 24 emergency helplines for flood-related assistance, with numbers available via their official website.
