One after the other, Low-Pressure Areas has been keeping the Monsoon active and has also led to a delay in the withdrawal of Monsoon.
A Cyclonic Circulation which is over South Andhra Pradesh coast will induce a Low-Pressure Area by tonight. This Low-Pressure Area will move towards Maharashtra rapidly and will merge with the Cyclonic Circulation over Madhya Maharashtra.
Post merging, this Cyclonic Circulation will travel to the Northeast Arabian Sea and will intensify into a Low-Pressure Area and will then be responsible for giving moderate to heavy rains over North Madhya Maharashtra, North Konkan and Goa including Mumbai as well as parts of South Gujarat.
On further moving westward, it may eventually intensify into a Depression around September 23 and will move away from the Indian coast.
Its impact in terms of rain activities over North Maharashtra and Gujarat will gradually fade away as it will move further west towards Oman coast.
Another Low-Pressure Area is expected to develop over Northwest Bay of Bengal around September 22 or 23. This system may move in the northwestward direction and as of now, indications are that it might impact Gangetic West Bengal, North Odisha and Jharkhand around September 24.
Moderate rains with few very heavy spells are very likely over these areas between September 24 to 26.
