Monsoon in Mumbai
Heavy rainfall across Mumbai since 25 September has resulted in waterlogging, travel disruptions, and the death of four people. The city received over 200 mm of rainfall between 1700 and 2200 hours on 25 September. The India Meteorological Department (IMD) has issued an orange alert for Mumbai and Thane and a red alert for parts of Palghar on 26 September.
Impact of the rainfall
The monsoon season in Mumbai typically lasts from June to September. According to the IMD, Mumbai recorded a nine percent increase in rainfall in 2024, and the monsoon retreat began a week later than usual. The heavy rainfall on 25 September is attributed to a low-pressure system over the West Central Bay of Bengal and adjoining Northwest Bay off the north Andhra-south Odisha coasts.
