There was least weather activity over most parts of the country covering North, Central and East India for the last few days. The pan India surplus of 13% rainfall till 24th October has come down to 9% now and may drop further. With this, the Southwest Monsoon has withdrawn completely from the country on 28th October 2020 bringing the curtains down on nearly 5 months old season.
The northeasterly winds have set in all along the East Coast, particularly over Coastal Andhra Pradesh and Tamil Nadu. Also, conditions are favourable for scattered rains over South Coastal Andhra Pradesh and Coastal Tamil Nadu for the next 48 hours. This marks the beginning of Northeast Monsoon 2020 which lasts till December. It spans over 5 sub-divisions namely; Tamil Nadu, Kerala, South Interior Karnataka, Rayalaseema, and Coastal Andhra Pradesh.
The rainfall of October is accounted for the Northeast Monsoon irrespective of its onset date. While Tamil Nadu and Kerala are deficient by 41% and 21% respectively, the other three sub-divisions are above normal by about 20% each. The rainfall activity is likely to pick up substantially next week.
