Rainfall Figures Across the City
According to the Brihanmumbai Municipal Corporation (BMC), cumulative rainfall recorded between 8:00 am on 1 July and 6:00 am on 3 July stood at 134 mm in Mumbai City, 164 mm in the Eastern Suburbs, and 149 mm in the Western Suburbs.
The single highest reading came from Mitha Municipal School in Mulund, which logged 218.6 mm. The S Ward Office followed with 212 mm, while Paspoli Municipal School in Powai recorded 208.4 mm. Gavanpada Fire Station and Mankhurd Fire Station registered 205.8 mm and 200 mm, respectively.

Alerts and Official Response
The IMD has placed Mumbai, Thane, and Raigad under an orange alert, warning of moderate to intense spells at isolated locations. Authorities have simultaneously issued a red alert for Palghar district, projecting extremely heavy rainfall over 24 hours. In response, the Palghar district administration declared a holiday for all schools and colleges.
The Thane Municipal Corporation stated that the Mayor has directed civic officials to remain on high alert and deploy all available resources to minimise inconvenience and ensure timely assistance to affected residents. Thane district is likely to receive very heavy rainfall over the next three days, according to the weather office.
Ground Situation in Thane and Palghar
Continuous showers since late Tuesday night triggered severe waterlogging across several residential areas. Localities including Ambernath, Kalyan, and Bhiwandi remained inundated, leaving residents stranded as stormwater drainage systems struggled to cope.
Palghar Disaster Management Cell Chief Vivekanand Kadam said the district had received very heavy rainfall, but no major untoward incidents or casualties had been reported as of late Wednesday evening.
What the IMD Forecast Says Next
The IMD has forecast heavy to extremely heavy rainfall across parts of western India through Thursday, with the southwest monsoon expected to remain active over the coming days. Notably, the weather office has flagged that a low-pressure area is likely to form over the northwest Bay of Bengal around 3 July. The system is expected to further energise monsoon activity, with Mumbai and the Konkan region likely to witness continued heavy to very heavy rainfall — and isolated extremely heavy spells — over the next several days.
With the monsoon showing no signs of retreat and a potential low-pressure system on the horizon, authorities across the Mumbai Metropolitan Region are bracing for an extended period of high rainfall and heightened civic stress.
Point of View
But the real story is structural: Mumbai's stormwater drainage systems once again buckled under a single sustained monsoon episode, not an unprecedented one. Mulund's 218.6 mm in 24 hours is heavy, but not historically exceptional for the city — yet the flooding response suggests infrastructure upgrades have not kept pace with the city's expansion. The IMD's low-pressure system warning for 3 July raises the stakes considerably: if that system intensifies, the BMC will face its first serious stress test of the 2025 monsoon season with drainage already overwhelmed and civic teams already stretched.
