Mumbai experienced heavy early-morning showers on Monday, with several areas recording over 20 mm of rain in just one hour, causing localized waterlogging and slowing traffic along major thoroughfares. The India Meteorological Department (IMD) has issued a yellow alert for the city, warning of intense rainfall spells continuing through midweek as monsoon currents strengthen over the Konkan coast.
According to the Brihanmumbai Municipal Corporation (BMC), rainfall between 8 am Sunday and 7 am Monday averaged 12.41 mm in the city (CT), 13.84 mm in eastern suburbs (ES), and 18.04 mm in western suburbs (WS). Specific hotspots included B. Nadkarni Park Municipal School in Wadala with 29 mm, Sewri Koliwada Municipal School 25 mm, and Storm Water Drainage Workshop in Dadar 24 mm. Eastern suburbs recorded Mankhurd Fire Station at 28 mm, Shivaji Nagar Municipal School 24 mm, and Chembur Fire Station 23 mm. In western suburbs, BKC Fire Station logged 26 mm, Pali Chimbai Municipal School 23 mm, and Bandra’s Supari Tank school 22 mm. While rainfall intensity was significant, the city did not face widespread waterlogging. However, minor inundation was reported at Sion’s Gandhi Market and patches along the Eastern Express Highway, causing slow vehicular movement during the morning commute. Local train operations on both Central and Western lines remained unaffected, highlighting the resilience of Mumbai’s suburban transport system despite heavy precipitation.
Meteorological experts highlighted that Monday’s downpour marks a resurgence of monsoon intensity after a relatively mild spell last week. Light to moderate showers are expected to continue through the day, with temperatures hovering between 27–31°C and high humidity levels making conditions uncomfortable for residents. Officials have advised commuters to plan extra travel time and remain cautious in low-lying areas prone to waterlogging. The IMD’s yellow alert indicates the possibility of localized heavy to very heavy rainfall across the city and suburbs, with orange alerts issued for districts such as Raigad, Palghar, and Nandurbar. Experts emphasised that urban infrastructure must continue evolving to withstand sudden high-volume rainfall, pointing to the importance of sustainable drainage solutions, climate-resilient road networks, and eco-friendly urban planning to mitigate flood risks in India’s megacities.
Urban planning officials said that while BMC has upgraded stormwater drainage systems in several vulnerable zones, extreme rain events highlight the challenges posed by rapid urbanisation. Temporary congestion on arterial routes such as the Eastern Express Highway and Sion’s key markets reflects the interplay between heavy rainfall and city mobility, underscoring the need for integrated climate-resilient transport and drainage strategies. As Mumbai braces for midweek intensification of monsoon activity, residents are urged to monitor weather updates and remain alert to potential localised waterlogging. Authorities continue to emphasise that preparedness, timely advisories, and sustainable urban infrastructure are central to maintaining mobility and safety during the monsoon season.
