There were no significant rail or road disruptions reported. However, authorities have warned citizens to stay alert before moving out of their houses, as heavy rainfall warnings continue on Monday.
Rainfall Surpasses Annual Average
The heavy rainfall over the weekend has taken total rainfall in Mumbai above its 12% annual average. The average annual rainfall for Mumbai is 2,207 mm, and the metropolis has received 111.63% of it till Sunday morning. As of Sunday, September 28, the eastern suburbs received 2,613 mm, western suburbs 2,612 mm, and the city area 2,164 mm.
Sufficient Water Storage Despite Rains
With changes in wind circulation over the Bay of Bengal, the IMD issued a fresh warning for increased rainfall from September 28 to 30 across Maharashtra. The interiors of the state are already struggling after recent flash floods, causing extensive agricultural loss. However, with the heavy rainfall in catchment areas, the lakes supplying water to Mumbai have reached 99.46% of their capacity, ensuring sufficient water storage and no water cuts for the city this year.
