Weather Alert: January Rains Recede as Dry Winds and Mist Take Over
The current rainy episode of January 2026 is officially coming to an end across Tamil Nadu. Starting today, January 26, dry winds moving from Central India will begin traveling through the state, replacing the previous moisture-heavy systems. By tonight or tomorrow morning, these dry conditions are expected to fully occupy the region, leading to a significant decrease in rainfall and the return of misty or foggy conditions.
Regional Rainfall Forecast (Next 24 Hours)
While the rain is tapering off, some areas will still experience precipitation over the next 24 hours before the dry air completely takes hold.
| Region | Expected Weather | Specific Districts |
|---|---|---|
| Kerala | Moderate Rain | Alappuzha, Ernakulam, Malappuram, and Kasaragod. |
| Tamil Nadu | Moderate Rain | Sivaganga, Tirunelveli, Tenkasi, West Virudhunagar, Theni, Kodaikanal, Valparai, and the Nilgiris. |
| Coastal TN & Delta | Light/Isolated Rain | Chennai, Tiruvallur, Kanchipuram, Chengalpattu, Cuddalore, Mayiladuthurai, Nagapattinam, and Tiruvarur. |
| Interior TN | Cloudy / Light Rain | Ranipet, Vellore, Tiruvannamalai, Salem, Erode, and Coimbatore. |
The Shift to Dry Weather
The atmospheric circulation that was present in the Comorin Sea area has completely weakened and disappeared. As a result, the weather pattern is shifting:
- Chennai and Suburbs: Light rain may persist until approximately 10:00 AM or 11:00 AM (the forenoon period), after which the rain will completely disappear.
- Delta Districts: Rainfall is expected to fully exit these areas following this evening or tonight.
- Interior Districts: Residents should prepare to see the effects of morning fog and mist starting from tomorrow morning.
Looking Ahead: February Outlook
The rainy "episode" for January is considered finished. Looking forward into February 2026, early indications suggest that the chances for rain will be very low. The region is expected to experience primarily dry weather throughout the coming month.
Due to this transition into a dry spell, weather updates will move to a weekly schedule until the next significant rain event develops.
