Northeast Monsoon 2026 Begins in Tamil Nadu with Orange Alert for Six Districts
IN · Published Nov 10, 2026
• The northeast monsoon has officially commenced over Tamil Nadu, Puducherry, and Karaikal, bringing fresh rainfall to the region. The Chennai Regional Meteorological Centre has issued an orange alert for six districts, including Nilgiris, Coimbatore, Theni, Dindigul, Tenkasi, and Madurai, warning of very heavy rainfall on Friday, 16 October
• Chennai is also expected to experience moderate rain with thunderstorms and lightning in some areas. The southwest monsoon has completely withdrawn from India, leaving Tamil Nadu with a 21% rainfall deficit for the season. Rainfall distribution during the northeast monsoon is expected to vary across the state, with northern districts likely to receive below-normal rainfall, southern districts above-normal rainfall, and coastal districts near-normal rainfall. Additionally, temperatures may remain slightly above normal due to the influence of strong El Niño conditions, which are expected to persist until February 2027.

Impact & Risks

The orange alert for six districts indicates the potential for very heavy rainfall, which could lead to localised flooding, waterlogging, and disruptions in daily life. Residents in Nilgiris, Coimbatore, Theni, Dindigul, Tenkasi, and Madurai should remain vigilant and prepare for possible adverse weather conditions. A yellow alert has also been issued for northern interior districts, southern districts, the Delta region, Puducherry, and Karaikal, where heavy rainfall is possible. In Chennai, moderate rain and thunderstorms may cause temporary disruptions in transportation and daily activities. Uneven rainfall distribution across Tamil Nadu could also impact agricultural activities and water resource management.
