The India Meteorological Department (IMD) has upgraded Mumbai and Thane's weather warning from a yellow alert to an orange alert as intense monsoon showers continue to batter the Mumbai Metropolitan Region (MMR). Meanwhile, Palghar district remains under a red alert, with forecasts of extremely heavy rainfall, strong winds of 60–70 kmph, and the possibility of severe flooding.
Persistent rainfall has affected several parts of the Mumbai Metropolitan Region (MMR), including Mira-Bhayandar, Vasai-Virar, Palghar, Dahanu, and Talasari. Flood-like conditions have been reported in many low-lying areas, while waterlogging has severely disrupted road and rail connectivity.
The Mumbai–Valsad corridor witnessed flash flooding, and transportation came to a halt in parts of Gholwad and Umbergaon due to inundated tracks and roads.
Considering the worsening weather conditions, the Palghar district administration declared a holiday for all schools, colleges, and Anganwadis on Thursday, July 23. Educational institutions in Mumbai, however, remain open as the Brihanmumbai Municipal Corporation (BMC) has not announced a citywide holiday.
According to official data, Mumbai received moderate to heavy rainfall during the 24-hour period ending at 8 am on July 23.

Thane's cumulative seasonal rainfall has now reached 1,890.98 mm, significantly higher than the 1,270.48 mm recorded during the same period last year.
Continuous rainfall has significantly improved Mumbai's water reserves. According to the Hydraulic Engineer's Department at Bhandup Complex, the city's seven lakes now hold 10,09,432 million litres (ML) of water, equivalent to 69.74% of the total useful live storage capacity.
Water stock increased sharply from 61.90% on July 22 to 69.74% on July 23, marking a rise of 7.84 percentage points in just 24 hours.
