Monsoon revivals often impact states in eastern and central India, including Uttar Pradesh, Bihar, Jharkhand, West Bengal, Odisha, and Chhattisgarh. These areas experience repeated spells of moderate to heavy rainfall, which can lead to waterlogging, rising river levels, and localized flooding. Northern states like Punjab, Haryana, and Delhi-NCR may also see increased rainfall as the monsoon trough oscillates.
