Mumbai, the bustling financial capital of India, is under a severe red alert as extreme rainfall batters the city today, unleashing torrents that have already paralyzed transportation, flooded low-lying areas, and prompted widespread evacuations. The India Meteorological Department (IMD) has forecasted 150-200 mm of rain in the next 24 hours, with isolated pockets in the western suburbs like Andheri, Bandra, and Dadar facing even heavier downpours of up to 250 mm.
