The southwest monsoon has further retreated from some other parts of Vidarbha, Chhattisgarh, many parts of Odisha, remaining parts of Jharkhand, West Bengal, Assam, Tripura, whole of Mizoram, Manipur, Nagaland, Arunachal Pradesh and many parts of North Bay of Bengal from Thursday (October 20).

And conditions will likely become favorable for further withdrawal from some other parts of Maharashtra, remaining parts of Chhattisgarh, Odisha and northern Bay of Bengal, and parts of Telangana, Andhra Pradesh, Yanam and the central Bay of Bengal by Saturday (October 22). .

Meanwhile, an area of ​​persistent low pressure over the northern Andaman Sea and adjacent areas of the southern Andaman Sea and southeastern Bay of Bengal is expected to gradually intensify into a cyclonic storm over the central west and adjacent central east of the Bay of Bengal by Monday (October 24).

The expected cyclone is likely to reach the coasts of West Bengal and Bangladesh on Tuesday, October 25, skirting the coast of Odisha. However, there are still differences between the models regarding the track and strength of the expected cyclone at this point. The ECMWF predicts that the system will hit the coasts of West Bengal and Bangladesh on Wednesday afternoon as a cyclonic storm (63-88 km/h). GFS expects the system to cross the east coast of Bangladesh early Tuesday morning as a severe cyclonic storm (89-117 km/h).

Earlier than the approach of the expected cyclone, heavy rains will start from Monday on the coasts of eastern India and northeastern India due to moist onshore winds winding around the system.

In addition to the cyclone, a westerly trough from the low pressure area over the northern Andaman Sea to the Tamil Nadu coast and another cyclonic circulation off western Kerala will produce strong rains over the extreme south of peninsular India for several days.

As for mercury levels, maximum temperatures will be near or slightly above normal over India during this projection period. Low temperatures will also be near or slightly above normal over India during the period, while below normal nightly lows are likely over inland parts of the southern peninsula of India.
