During 24 to 48 hours monsoon may withdraw from entire Uttar Pradesh, parts of Bihar, Jharkhand, North Chhattisgarh, most parts of Madhya Pradesh and Gujarat. And in subsequent two days it may withdraw from West Bengal, parts of Odisha and Maharashtra.
A low-pressure area is developing over Bay of Bengal which will eventually intensify into a cyclone and may move towards South Odisha and North Andhra Pradesh coast.
