A depression formed on October 18 in the central Bay of Bengal, and moved to the north. It gradually intensified and turned to the northeast, becoming a cyclonic storm on October 20. The storm became the second severe cyclonic storm of the season on the following day, and turned onto a more northerly track towards the Ganges Delta. The storm peaked with winds of 130 km/h (80 mph) before it made landfall near the West Bengal–East Pakistan border, during the morning of October 23. The storm then crossed over East Pakistan, before dissipating over southern Assam on October 24.
