Mumbai and the Konkan region around it are in alert mode since the India Meteorological Department (IMD) has issued a Yellow Alert on September 26, 2025, predicting heavy rain with thunderstorms, lightning, and gusty winds. The alert is for districts such as Thane, Navi Mumbai, Palghar, Raigad, Ratnagiri, and Sindhudurg. The warning suggests that it is expected to see severe weather in these regions, with wind speeds of 30–40 km/h and the risk of local flooding and disruption.
Weather Outlook and Regional Impact
The prevailing weather situation is characterized by a low-pressure system forming over the Bay of Bengal, which will further develop into a depression by September 27. The system is expected to cause widespread very heavy to heavy rainfall over Maharashtra, mainly over the Konkan and Madhya Maharashtra.
In Mumbai, the IMD predicts scattered heavy showers during the day, with the maximum temperatures hovering at 29–30°C and the minimums at 27°C. The Santacruz observatory saw a high of 30.9°C and a low of 24.6°C on Thursday, while Colaba observed a high of 30.4°C and a low of 25°C. Mid-day The warning from the IMD also includes possible risks like waterlogging, traffic congestion, and high sea conditions along the coast. People are told to remain indoors during showers, keep away from low-lying areas that are susceptible to flooding, and be cautious near the coast due to the likelihood of high tide and strong winds.
Tidal and Reservoir Conditions
Tidal activity is also closely watched. There is expected to be a high tide at 3.70 meters at 1:57 pm followed by a low tide at 0.85 meters at 7:51 pm. Another high tide at 3.91 meters is predicted at 2:38 am on September 27, while the next low tide at 2.00 meters is due at 8:11 am on the same day. Such tidal levels might add to the effects of rain, especially in the coastal and low-lying regions.
Mid-day
On the side of water availability, Brihanmumbai Municipal Corporation (BMC) reports that their combined storage in the seven reservoirs feeding drinking water to Mumbai has increased to 99.18% of their total capacity, after heavy rains fell in their catchment areas.
The seven reservoirs are Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vehar, and Tulsi lakes.
Though this rise in water levels is a welcome improvement, it also calls for caution against possible flooding and the management of excess water.
