Cyclonic system strengthens
The low-pressure area over South Andaman and adjoining areas (cyclonic circulation) continues to persist over the same region as of 8:30 a.m. on Friday. It is likely to move west-northwestward and intensify into a low-pressure system over the southeast Bay of Bengal and adjoining Andaman and Nicobar Islands, and the Andaman Sea on Saturday (Oct. 31). Following this, the system is expected to move west-northwestward toward the Andhra coast over the next two days.
Chance of rain: As a result, on Saturday (Oct. 31), light rain is likely at one or two places in the Western Ghats districts, coastal Tamil Nadu, and in Puducherry and Karaikal.
Similarly, on Nov. 1, light to moderate rain accompanied by thunder, lightning, and strong winds may occur in the northern coastal districts, the Western Ghats districts, Madurai, Tiruchi, Namakkal, Salem, Erode, and Karur districts, as well as in Puducherry and Karaikal.
There is a chance of light rain in Chennai and suburban areas on Saturday (Oct. 31). However, the maximum daytime temperature will be around 95 degrees Fahrenheit.
