Tamil Nadu braces for a mix of fog and fleeting light rains as a potential low-pressure area forms in the southeast Bay of Bengal, warns the Chennai RMC. The trigger is an existing upper-air cyclonic circulation spanning the equatorial Indian Ocean and adjacent Bay regions.
Around February 16, this could coalesce into a low-pressure system, nudging weather in Tamil Nadu, Puducherry, and Karaikal. Dry spells should hold from February 15-18, but watch for patchy light precipitation on February 19-20 at select spots.
Broad rainfall isn’t expected, yet the system’s dynamics might spark isolated surprises. Vigilance is key for those along the coast, with officials recommending constant forecast checks.
Northern districts face fog threats too. Moderate haze is likely in Chennai, Tiruvallur, Kanchipuram, and Chengalpattu on the 15th, spreading further to Villupuram and Cuddalore by the 16th.
This could slash morning visibility, hampering highway and suburban commutes. Vehicle operators: Exercise prudence, dim lights for oncoming traffic, and avoid high speeds.
With ongoing tracking of Bay of Bengal activities, the IMD promises prompt updates. Tamil Nadu residents, heed these advisories to navigate the fog and potential drizzles effectively, safeguarding daily routines.
