Rainfall warnings include light to moderate rainfall at most places with heavy to very heavy rainfall expected in specific areas of North Coastal Tamil Nadu, Puducherry, Coastal Andhra Pradesh, Rayalaseema, and Odisha. Wind warnings indicate gale wind speeds and squally conditions in the Bay of Bengal and along various coastal regions.

Sea conditions are expected to be very rough to high in the southwest Bay of Bengal and along the north Tamil Nadu-Puducherry coasts until the morning of December 4 (UTC), with similar conditions in the west-central Bay of Bengal and along the south Andhra Pradesh coast. Fishermen are advised against venturing into certain sea areas until December 6 (UTC).

A storm surge of about 1 – 1.5 m (3.3 – 4.9 feet) above the astronomical tide is likely to inundate parts of south coastal Andhra Pradesh at the time of landfall. Expected damages include impacts on various structures, agriculture, and possible flooding and landslides in affected areas.

Residents are advised to take necessary precautions, including suspending fishing operations, avoiding vulnerable areas, and staying indoors.
