Incessant rains induced by a deep depression since early Monday (August 17, 2026) morning heavily affected normal life in Kolkata and its adjoining areas, with waterlogging exacerbating traffic snarls during office hours.

The India Meteorological Department (IMD) said the depression over coastal West Bengal and northwest Bay of Bengal is likely to move towards Jharkhand across Gangetic West Bengal by Tuesday (August 18).
