Tamil Nadu’s heavy rain alert is set to affect multiple regions over the next six days, with the Chennai weather centre forecasting intense showers in the Nilgiris and Coimbatore on November 5, followed by heavy rain in seven districts on November 6 and further spells in southern districts through November 11.
According to the weather centre’s forecast cited by Dinamalar, heavy rain is likely in the Nilgiris and Coimbatore on November 5. The warning places two districts in western Tamil Nadu under the immediate heavy-rain watch, while the forecast for the following days shifts towards the state’s northern, delta and southern regions.
For November 6, heavy rain is expected in Chengalpattu, Viluppuram, Cuddalore, Mayiladuthurai, Kanniyakumari, Nagapattinam and Tiruvarur. Moderate rain is forecast in Thanjavur, Virudhunagar, Tenkasi, Thoothukudi, Ramanathapuram, Sivaganga, Pudukkottai and Tirunelveli on the same day.
The forecast also indicates that isolated heavy rain could occur in Dindigul, Madurai and Theni on November 7. These districts form part of Tamil Nadu’s interior and southern belt, where rainfall conditions may affect road movement, local transport and routine public activity when intense spells occur.
The weather centre’s outlook extends beyond the immediate 48-hour period. The report says heavy rain may continue at isolated places in Tamil Nadu, Puducherry and Karaikal until November 11. The supplied forecast also refers to heavy rain over parts of the state on November 8, but the district-wise details in the published text are incomplete and are not reproduced here as a confirmed list.
The spread of the forecast across western, northern, delta and southern districts means that the rain alert is not confined to one urban region or one weather system impact zone. Residents in the named districts will need to follow further updates from the weather authorities, particularly where district administrations issue local advisories or alter arrangements for travel and public services.
The next confirmed milestones in the forecast are the heavy-rain outlook for the Nilgiris and Coimbatore on November 5, the seven-district alert for November 6, the isolated heavy-rain possibility in Dindigul, Madurai and Theni on November 7, and the continuation of the broader rainfall outlook through November 11.
