New Delhi: After witnessing the havoc and devastation created by sudden rainfall which turned into floods, finally states witnessing heavy downpour can take a sigh of relief as IMD has predicted the withdrawal of southwest monsoon completely from the entire country around October 26, paving the way for the commencement of the northeast monsoon,

After monsoon had withdrawn from most parts of the country around October 15 except a small part of east India, the formation of two low-pressure areas over the Bay of Bengal and the Arabian Sea led to widespread rain over east Odisha, West Bengal, Kerala, and parts of northwest India, delaying monsoon withdrawal.

The southwest monsoon withdrawal line currently passes through Kohima, Silchar, Krishnanagar, Baripada, Malkangiri, Nalgonda, Bagalkote, and Vengurla.

Conditions are becoming favourable for further withdrawal of the southwest monsoon from remaining parts of northeast India, the entire north Bay of Bengal, remaining parts of West Bengal and Odisha, some parts of the central Bay of Bengal, parts of Andhra Pradesh and Telangana, entire Goa, some more parts of Karnataka and some more parts of central Arabian Sea around October 23, the IMD said.

With likely setting in of northeasterly winds in the lower tropospheric levels over the Bay of Bengal and extreme south Peninsular India, the Southwest Monsoon is likely to withdraw from the entire country around 26th October 2021. Simultaneously, the Northeast Monsoon rains are also likely to commence over Southeast Peninsular India from around 26th October 2021, the Met department said.

However, a cyclonic circulation is lying over Bihar and the neighborhood. Under its influence, fairly widespread, light to moderate rainfall with isolated heavy fall and thunderstorms & lightning is very likely over Arunachal Pradesh, Assam & Meghalaya, Tripura, Sub Himalayan West Bengal & Sikkim on Thursday and it will reduce thereafter.

Isolated extremely heavy falls are also likely over the sub-Himalayan West Bengal, Sikkim on October 20 and very heavy falls over Arunachal Pradesh, Assam, and Meghalaya on the same day, said IMD.

There will be rainfall activity over Kerala, Tamil Nadu, Puducherry, coastal and south interior Karnataka during October 20-24.

The northeast monsoon brings rains over Tamil Nadu, parts of Kerala, Andhra Pradesh, Karnataka, Puducherry and Andhra Pradesh.

The withdrawal of the southwest monsoon from northwest India commenced on October 6. The retreat was the second-most delayed withdrawal of the southwest monsoon since 1975. The southwest monsoon withdrawal from northwest India in 2019 started on October 9.

The withdrawal of the southwest monsoon from northwest India usually begins on September 17.

However, the southwest monsoon remains active over several parts of the country.
