Although the low-pressure area in the Bay of Bengal has dissipated, its lingering effects combined with humid sea winds are keeping the atmosphere unsettled. Moderate downpours are anticipated in parts of southern and northern Tamil Nadu.

Light to moderate showers are also forecast for Puducherry and Karaikal. Rainfall activity across the state may extend through March 1, influenced by changing wind patterns and increased moisture.

Morning fog is expected in multiple districts including Tiruvallur, Kanchipuram, Salem, Dharmapuri, Krishnagiri, Tirupattur, Vellore, and Ranipet on Wednesday and Thursday. This could impair visibility on key routes, leading officials to warn motorists about heightened risks.

Adding to the variability, daytime highs will climb above average by 2-3 degrees Celsius until February 28 in Tamil Nadu and Puducherry. Such contrasting weather patterns signal typical shifts in regional meteorology.

Residents in agriculture-dependent zones are encouraged to stay informed via local forecasts. Continuous monitoring by meteorologists will yield fresh warnings and guidance as the situation develops.
