There are likely to be two low-pressure cyclonic systems in the North Andaman Sea and the Bay of Bengal, one after the other over the next week, according to the Indian Meteorological Department (IMD). The systems will bring above normal rainfall to most of the country, except for the northwestern and western Himalayan regions and the southernmost part of mainland India.
The two low-pressure systems will also prevent the retreat of the southwest monsoon, according to forecasts. “The withdrawal of the southwest monsoon will not be possible due to the two consecutive low pressure systems. It will only happen after October 22, ”said Dr. AK Das, lead scientist at IMD. The monsoon retreat begins on September 17 in northwestern India and is completed on October 15.

The first low-pressure system will form over the northern Andaman Sea and the adjoining Bay of Bengal on Friday and will move from west to northwest towards northern Andhra Pradesh and the southern coast of Odisha and arrive there as a deep depression around October 11 in the afternoon.
The second system will develop on October 14 and will intensify into a cyclonic disturbance over the next two days. On Thursday, IMD met with all agencies to prepare for the cyclone season between October and December, when conditions are favorable for a cyclone.
This year there have been two cyclones, Amphan in May and Nisarga in June.
With winter approaching, night temperatures are likely to remain below normal in northwest India this week, according to IMD.
