Light to moderate spells are anticipated over the capital city of Tamil Nadu. Moreover, places such as Puducherry, Cuddalore, Karaikal, Parangipettai, and Thanjavur are expected to witness rains. However, there is no need to panic as heavy to very heavy rains are not in the forecast and usual pattern of Northeast Monsoon rains would appear.
The weak phase of Northeast Monsoon is expected to revitalize during the next few days. As per weathermen, a low-pressure area is expected to develop over South Andaman Sea around Christmas, however, we will have to wait and see whether it will travel towards Tamil Nadu Coast or recurve towards North Bay of Bengal.
