Overview

• IMD measured about 251.4–251.6 mm of rain in under 24 hours, the city’s heaviest single-day total since the 1980s and among the top six in 137 years.
• Large swathes of southern and eastern Kolkata stayed waterlogged, with pumps deployed as Metro sections, suburban rail, roads and dozens of flights faced suspensions or delays.
• The state advanced school and college holidays for Durga Puja by two days, and organisers reported damaged pandals and artwork across the city.
• Chief Minister Mamata Banerjee faulted power distributor CESC over electrocution deaths; the utility said many incidents involved internal wiring and assets it does not maintain.
• The IMD issued an orange alert for parts of West Bengal, cautioning of further rain from Bay of Bengal low-pressure systems even as some services gradually resume.
