Overview

• Mumbai’s seven supply reservoirs hold roughly 99% of capacity, easing short‑term water‑supply worries but requiring close overflow management, according to BMC data.
• Mumbai has already exceeded its September rainfall average, with the Santacruz observatory logging 393 mm by September 20, IMD figures show.
• Localized downpours continue to disrupt travel, including a 60 mm daytime burst at Santacruz and a 140.6 mm 24‑hour deluge at Pune’s Pashan, which triggered waterlogging and traffic snarls.
• IMD maintains yellow alerts across parts of Maharashtra, including Thane, Raigad and Pune, with light to moderate rain and isolated heavy spells forecast through late September.
• Kolkata faces mostly cloudy skies with light to moderate rain and gusty winds through October 2, and authorities have issued coastal cautions for high tides and rough seas in affected regions.
