The India Meteorological Department (IMD), the government's weather agency, has forecast heavy rain at isolated places in parts of Tamil Nadu this week.
The forecast also covers Puducherry and Karaikal.
The agency said this on Tuesday, and the warning is for several days, including November 15 and 16.
Key points
- Heavy rain is likely at isolated places, meaning only some spots, not the whole district.
- Ramanathapuram and Thoothukudi may get heavy rain on November 12.
- Nilgiris and Coimbatore may get heavy rain on Monday, November 16.
- Chennai is not mentioned in the warning.
Which districts are at risk, and on which days?
The district details come from a seven-day forecast issued on November 10. It names specific areas for specific days.
Ramanathapuram and Thoothukudi are listed for November 12. These are in the south of the state.
On Sunday, November 15, heavy rain is likely at some places in Thanjavur, Thiruvarur, Mayiladuthurai and Nagapattinam.
The Karaikal area is also included.
On Monday, November 16, the hill district of Nilgiris and Coimbatore are listed.

So why is Chennai missing from the warning?
The warning does not mention Chennai at all. This does not mean the city will have no rain, only that it is not in this list.
The weekly forecast had said fairly widespread to widespread rain was likely over Tamil Nadu and Puducherry on Sunday.
That is a larger area than the isolated rain in the new warning.
So the two forecasts describe different things. "Isolated" means a few spots, while "widespread" means a much larger area.
What should residents keep an eye on?
Residents in the listed districts should watch for updates from the weather department as the dates come closer.
The IMD has issued forecasts for both the short term and the coming week. Updates may change the picture for specific areas.
Explainer
What happened before
- On November 10, the IMD issued a seven-day forecast with district-specific details.
- A day before the latest warning, the weekly forecast said fairly widespread to widespread rain was likely on Sunday.
Why it matters
Several districts in Tamil Nadu and Puducherry may see rain this week, which can affect travel and daily work.
What to watch next
- The IMD has forecast rain on November 12, 15 and 16, so updates from the weather department will matter.
