The financial capital of India, Mumbai, is once again in the spotlight due to extreme monsoon activity. The India Meteorological Department (IMD) has issued a Mumbai red alert heavy rainfall warning, cautioning residents about severe weather conditions that may persist for the next 48 hours. With heavy to extremely heavy showers lashing the city, waterlogging, traffic snarls, suburban train delays, and flooding have paralyzed normal life.
In this article, we will cover the latest updates on the Mumbai rainfall news, the science behind this weather system, the impact on daily life, emergency precautions, and what residents should expect in the coming days.
What Does “Mumbai Red Alert Heavy Rainfall” Mean?
The red alert is the highest level of weather warning issued by the IMD. It indicates the possibility of extremely heavy rainfall (over 204.5 mm in 24 hours) in one or more areas. For Mumbai, a red alert is a signal for:
-
Dangerous flooding in low-lying regions.
-
Severe traffic congestion due to waterlogging.
-
Disruption of local trains and flights.
-
High tide risk worsening the flood situation.
This alert is not just about rainfall but also about preparedness, urging civic bodies, police, and emergency services to remain on high alert.
Current Mumbai Weather Conditions
As of August 18, 2025, Mumbai is witnessing non-stop heavy rainfall, with several parts of the city recording triple-digit millimeters of rainfall within 24 hours.
-
Santacruz Observatory reported 245 mm rainfall, the heaviest August downpour since 2020.
-
Colaba Observatory recorded over 180 mm rainfall.
-
Areas like Andheri, Vile Parle, Kurla, and Dadar are among the worst affected with severe waterlogging.
The continuous showers, combined with high tide timings, have created a flood-like situation in many parts of the city.
Impact of Heavy Rains in Mumbai
The Mumbai red alert heavy rainfall has disrupted daily life significantly:
1. Waterlogging in Key Areas
Several major roads and junctions are submerged, causing massive traffic jams.
-
Western Express Highway near Vile Parle and Andheri is partially submerged.

Eastern Freeway reported waterlogging at multiple spots.
-
Sion Circle, King’s Circle, Chembur, and Kurla remain heavily affected.
2. Public Transport Chaos

-
Some BEST buses have been diverted due to flooding.
-
Flight operations at Chhatrapati Shivaji Maharaj International Airport have been delayed, with airlines issuing advisories to passengers.
3. Traffic Snarls
With waterlogged roads and breakdowns, commuters are stranded for hours. The traffic police have urged citizens to avoid unnecessary travel.
4. Health Concerns
Continuous rains and flooding raise the risk of waterborne diseases like dengue, malaria, and leptospirosis. The Brihanmumbai Municipal Corporation (BMC) has set up emergency medical teams.
IMD Forecast for Mumbai
The IMD red alert for Mumbai is valid until August 19, 2025, with predictions of:
-
Very heavy rainfall (115.6 mm – 204.4 mm) in some pockets.
-
Extremely heavy rainfall (above 204.5 mm) at isolated places, particularly in suburban areas and coastal belts.
-
Strong winds along the Konkan coast and high tide conditions worsening waterlogging.
Other parts of Maharashtra, including Thane, Raigad, Ratnagiri, and Pune’s ghat areas, are also under red and orange alerts.
Why is Mumbai Facing Heavy Rainfall?
The current weather system is linked to a low-pressure area over South Chhattisgarh and Odisha, which is pushing strong monsoon currents into Maharashtra.
This system, combined with the Western Ghats’ geography, causes orographic rainfall, resulting in heavy showers in Mumbai and the Konkan belt.
Comparisons with Past Mumbai Rainfall Disasters
Mumbai has a long history of monsoon-related disasters:
-
July 26, 2005: Mumbai recorded 944 mm rainfall in a single day, leading to one of the deadliest floods in India’s history.
-
August 29, 2017: Over 300 mm rainfall caused severe flooding, stranding thousands.
-
August 2020: Santacruz recorded 331.4 mm rainfall, the highest in 46 years.
While today’s rainfall is not yet as extreme as 2005, the red alert signals the potential for similar disruptions if showers intensify further.
Government and Civic Body Response
The BMC (Brihanmumbai Municipal Corporation) and Maharashtra state authorities have initiated several precautionary measures:
-
Emergency control rooms are on round-the-clock duty.

Disaster response teams have been deployed in vulnerable areas.
