Mumbai is experiencing its most severe monsoon rainfall period in five years

The cause of such prolonged and heavy precipitation was a combination of a low-pressure area over the Bay of Bengal and a weather trough over the Arabian Sea. This led to continuous downpours instead of the brief showers typical of the monsoon season.

The consequences for the metropolis have been severe:

• Large-scale flooding: Many areas were waist-deep in water, paralyzing traffic.
• Transportation disruptions: Suburban train services were suspended and delayed, and flights were canceled and delayed. Due to waterlogging, the routes of 135 bus lines were altered.
• Power outages and closure of institutions: Due to the difficult situation, educational institutions and government offices were closed, and private-sector employees were advised to work remotely.
• Evacuations and casualties: More than 600 people were evacuated from a stalled monorail, with hundreds relocated to temporary shelters. Across the state, at least 21 fatalities have been recorded since August 15 due to weather-related incidents.
• Agriculture: Crops over 12-14 lakh hectares across Maharashtra have been severely affected.

The India Meteorological Department (IMD) issued the highest danger level (red alert) for Mumbai for several days in a row. The intensity of the rain is expected to diminish; however, authorities are urging residents to avoid unnecessary travel and remain vigilant. Cleanup and road repair efforts are currently underway in the city.

• Precipitation: About 891 mm for the month; over 360 mm in 24 hours in some areas
