Mumbai experiences heavy to very heavy rainfall; residents urged to avoid unnecessary travel as IMD issues red alert in parts of Maharashtra.

Karnataka receives heavy downpour, Almatti dam outflow increases raising concerns of flooding in downstream areas.

Authorities monitor water levels, issue warnings, and deploy teams for relief and rescue operations in affected regions.
The Indian monsoon has once again brought intense rainfall across several states, with Mumbai, Karnataka, and Maharashtra witnessing heavy to very heavy showers in the past 24 hours. The India Meteorological Department (IMD) has issued red and orange alerts for multiple regions, cautioning citizens about possible flooding, waterlogging, and traffic disruptions.
Heavy Rains Lash Mumbai
In Mumbai, heavy downpours since late last night have caused significant waterlogging in low-lying areas, leading to traffic congestion across several arterial roads. Train services on the Central and Western Railways are experiencing minor delays, though local authorities have assured that restoration teams are on standby.
The Brihanmumbai Municipal Corporation (BMC) has issued an advisory requesting residents to avoid unnecessary travel, especially during peak rainfall hours. Schools in a few districts have been instructed to remain closed as a precautionary measure.
Experts note that Mumbai’s drainage infrastructure comes under severe pressure during intense short bursts of rain, leading to flooding in areas like Dadar, Sion, Kurla, and Andheri. With the IMD predicting more rainfall over the next 48 hours, authorities are on high alert.
Almatti Dam Outflow Rises in Karnataka
In Karnataka, heavy rains in the upper catchment areas have led to an increase in water levels at the Almatti Dam, one of the state’s largest reservoirs on the Krishna River. Authorities confirmed that controlled water outflow has been initiated to prevent overflow and ensure dam safety.
This rise in dam outflow poses potential risks for downstream villages in Bagalkot, Vijayapura, and Raichur districts. The Karnataka government has asked residents in vulnerable areas to move to safer locations if water levels rise further.
The State Disaster Response Force (SDRF) has been placed on high alert, with rescue boats and relief materials pre-positioned. District collectors have been asked to keep evacuation shelters ready in case of emergencies.
Monsoon Intensity in Maharashtra
Apart from Mumbai, other parts of Maharashtra including Konkan, Raigad, Ratnagiri, and Thane districts are witnessing very heavy rainfall. In some regions, rainfall has crossed 200 mm in 24 hours, leading to swollen rivers and high risk of landslides in hilly terrain.
Farmers in the state have expressed mixed feelings about the rainfall. While sufficient monsoon showers benefit paddy and sugarcane cultivation, excessive rains and flooding pose risks to standing crops.
The Maharashtra State Disaster Management Authority (MSDMA) has been issuing regular advisories and has urged people living near rivers and dams to remain cautious.
IMD Forecast and Warnings
According to the IMD, heavy to very heavy rainfall is expected in:
-
Mumbai Metropolitan Region
-
Konkan-Goa belt
-
Coastal Karnataka
-
Parts of Telangana and Andhra Pradesh
Isolated extremely heavy rainfall events are also forecast in some districts. The IMD has advised fishermen not to venture into the Arabian Sea due to strong winds and high waves.
Civic and Government Response
Local governments in both Maharashtra and Karnataka have activated disaster management protocols. Control rooms have been set up, and emergency contact numbers have been widely circulated through television, radio, and social media.
The Mumbai Police have increased patrolling in flood-prone zones, while the National Disaster Response Force (NDRF) is monitoring the situation closely.
Impact on Daily Life and Economy
-
Transport: Mumbai’s suburban rail, Metro, and BEST bus services have been hit by delays, inconveniencing lakhs of commuters.
-
Air Travel: Flight operations at Mumbai airport are functioning but with minor delays due to reduced visibility.
-
Agriculture: Farmers are worried about soil erosion and damage to standing kharif crops.
-
Businesses: Many offices have adopted work-from-home advisories for employees during peak rainfall days.
Precautionary Measures for Residents
Authorities have issued the following safety guidelines:
-
Avoid unnecessary travel during heavy rain hours.
-
Do not venture near rivers, dams, or overflowing drains.
-
Keep emergency kits with water, medicines, and essentials ready.
-
Stay tuned to official weather updates and advisories.
Long-Term Monsoon Concerns
Experts say that climate change is intensifying rainfall patterns in India, with short, heavy spells becoming more frequent. This leads to higher risks of urban flooding, crop losses, and dam management challenges.
Mumbai, being a coastal megacity, remains vulnerable to sea-level rise combined with heavy rains, raising long-term concerns about its resilience. Similarly, Karnataka’s reliance on large reservoirs like Almatti makes water management during extreme rains a critical issue.
The current monsoon spell in Mumbai, Karnataka, and Maharashtra is a reminder of the increasing challenges posed by extreme weather events. With coordinated efforts from IMD, state governments, and civic bodies, preparedness and timely response will be key to reducing risks and protecting lives.
