Fresh disturbance over South Andaman Sea

A new low-pressure area is likely to form over the South Andaman Sea within the next 24 hours. Numerical weather models indicate that it may initially move westward and reach the south-central Bay of Bengal by December 9. From there, its trajectory will depend on its intensification:

*If the system strengthens:* It is likely to move northwestward and approach the Tamil Nadu coast by December 12

*If it remains weak:* It will continue westward, bringing rainfall primarily to South Tamil Nadu and Sri Lanka.

The intensification depends on various atmospheric factors, which are being closely monitored. Updates will be shared as the system evolves.

Forecast for the Next 3 Days:

Predominantly dry conditions will prevail across most parts of Tamil Nadu, including the KTCC districts with scattered showers may occur in isolated areas.Nights and mornings are expected to cool,  while daytime will be warm with sunny skies.
