5-day nationwide forecast
The withdrawal line of the Southwest Monsoon continues to pass through Jammu, Una, Chandigarh, Karnal, Baghpat, Delhi, Alwar, Jodhpur and Nalia. However, its pace will be delayed due to a cyclonic circulation forming off the northeast coast of Andhra Pradesh. It will slightly travel towards the Bay of Bengal’s centre until Monday but return to the subcontinent after Tuesday, then make landfall on Wednesday.
At the same time, an east-west trough runs from the Westcentral Bay of Bengal off Andhra Pradesh coast to Coastal Karnataka at lower tropospheric levels.
As a result, widespread rain is very likely over the eastern half of the subcontinent after Tuesday due to hot and humid south easterly or easterly winds.
Furthermore, scattered to fairly widespread light/moderate rainfall with isolated heavy falls is very likely over East Madhya Pradesh, Chhattisgarh, Bihar, Sub-Himalayan West Bengal and Sikkim on October 4-5; over Jharkhand from October 3-5; over Gangetic West Bengal, Assam and Meghalaya during October 2-5; over Odisha from October 1-5; over Andaman & Nicobar Islands on October 1,3 and 5; and over Nagaland, Manipur, Mizoram & Tripura from October 1-3.
As for mercury levels, both daytime & nighttime temperatures will be extreme or quite higher than normal over much of Trans Himalayas and W.Himalayan, at least until mid-October.
