Overview

• IMD recorded about 251 mm of rain in 24 hours, with southern and eastern neighborhoods hardest hit in a downpour described as the most intense in decades.
• Officials reported at least 12 fatalities, including nine electrocutions in Kolkata, as waist-deep water, power outages and flooded streets trapped residents and stalled recovery.
• Mamata Banerjee blamed CESC for the electrocutions and criticized upstream water management, while the utility said its network was not at fault and cited faulty internal wiring and non-CESC poles.
• CESC said it proactively switched off supply in waterlogged pockets and reported restoring about 50–60% of operations by late Tuesday, with full restoration dependent on water receding.
• The state advanced Durga Puja school holidays and suspended classes, authorities continued pumping operations as water slowly receded, and the IMD maintained an orange alert for more heavy rain in the coming days.
