Intense Rainfall Hits Mumbai Early Morning, Meteorological Department Issues Severe Warnings; Further Rainfall Predicted for the Week
Mumbai and nearby areas are bracing for heavy rain, thunderstorms, and potential flooding as a low-pressure system moves over south Madhya Maharashtra and its neighbouring regions. The India Meteorological Department (IMD) has issued orange alerts for Navi Mumbai, Thane, and Kalyan, warning of heavy rainfall and possible flooding. Several areas in Mumbai, including Borivali, Santacruz, Powai, Mulund, Chembur, Worli, Colaba, and Alibag, are on red alert for very heavy rain and thunderstorms [1][3][5].
Raigad is also on red alert for very heavy rain and local flooding. Strong winds and thunderstorms are likely in Raigad, Thane, and Palghar. The southwest monsoon has arrived early in Maharashtra, the earliest in 35 years, and Mumbai is expected to experience heavy rain, thunderstorms, high winds, and associated risks to transport and safety [1][3][5].
According to data from August 2025, Mumbai faces heavy to very heavy rainfall, frequent thunderstorms, strong winds up to around 39 km/h, and high humidity (around 85-90%), leading to risks such as waterlogging, flooding, and disrupted traffic [1][3][5]. Flood risk is heightened by saturated urban drainage and heavy rain intensity, while thunderstorms could bring gusty winds and lightning hazards.
Given these patterns typical of Mumbai’s monsoon in 2025, we can infer that on a similar date like May 26 (close to the monsoon onset), the city would likely be experiencing heavy rain, thunderstorms, potential flooding, high winds, and associated risks to transport and safety.
The IMD predicts more rain throughout the day in Mumbai. People in the city are advised to carry umbrellas, avoid low-lying areas, and plan for delays due to waterlogging. Fishermen have been warned not to venture into the sea as rough weather is expected to continue over the next few days [1][3][5].
The southwest monsoon is expected to reach Mumbai in the next few days, much before the usual date of June 11. Mumbai will have a cloudy sky with heavy showers, and temperatures will stay between 24°C and 31°C [1][3][5].

Weather-forecasting data from August 2025 suggests that Mumbai would likely experience heavy rain, thunderstorms, potential flooding, high winds, and associated risks to transport and safety on similar dates.
Given the early arrival of the southwest monsoon in Maharashtra, the India Meteorological Department (IMD) routinely provides weather predictions for the city, advising people to carry umbrellas, avoid low-lying areas, and plan for delays due to waterlogging.
