Chennai: The Chennai Regional Meteorological Department has issued a multi-day heavy rainfall warning for Tamil Nadu, with four districts placed on high alert for today, October 14, 2025. For today, heavy rain is likely at one or two places specifically in the hilly areas of Coimbatore district, the Nilgiris, Theni, and Tenkasi districts. A broader pattern of light to moderate rain with thunder and lightning is expected at many places across Tamil Nadu, Puducherry, and Karaikal.

The weather agency has attributed the persistent wet spell to twin low-pressure areas prevailing over South Coastal Andhra Pradesh and the Southeast Arabian Sea. The forecast predicts a significant expansion of the heavy rainfall belt over the coming days, set to drench southern and coastal districts extensively.
