Setting at rest apprehensions, the South-West Monsoon has started being active over the south peninsular region, after remaining subdued for nearly five days.

According to the India Meteorological Department, the system has now advanced into entire Tamil Nadu, some parts of south interior Karnataka, and some parts of Rayalaseema and coastal Andhra Pradesh.

The northern limit of the system on Saturday passed through Kannur in Kerala, Bangalore, Kadapa and Bapatla in Andhra Pradesh, and Agartala, Dhubri and Gangtok in the north-east.

The department predicted that during the next three days, fairly widespread rainfall or thunder-showers would occur over Lakshadweep, Kerala, coastal Karnataka and Andaman and Nicobar Islands, scattered rainfall over interior Karnataka, Rayalaseema, and Tamil Nadu and isolated rainfall over coastal Andhra Pradesh and Telangana.

At a press conference on Friday, IMD Director-General Ajit Tyagi said a fresh strong surge of monsoon flow was on its way, with the weakening of the cyclonic storm over the Arabian Sea.

The storm has lost much of its steam and lay centred around 600 km off Karachi in Pakistan and 800 km north-north-west off Naliya in Kutch district of Gujarat.

Weather prediction models indicated that it could weaken further and bring some good rains to Delhi and other parts of north India during the next two to three days.
