The India Meteorological Department (IMD) forecasts heavy to very heavy rainfall across parts of southern India, with thunderstorms and gusty winds expected in several areas. Multiple outlets highlight Tamil Nadu, Puducherry and Karaikal as key locations for intense rain, including “isolated very heavy” rainfall, alongside continuing wet conditions over the coming days.

Coverage links the rainfall to developing weather systems in the Bay of Bengal and nearby regions. One report says a low-pressure area forms over the southwest Bay of Bengal, while another describes moisture-laden cloud building and a cloud mass tied to an easterly wave moving from the Sumatra/Gulf of Thailand region toward the Andaman Sea.

Outlets also differ in how they map the warning. NDTV focuses on the heavy rain warning tied to Tamil Nadu, Puducherry and Karaikal until October 26, while Times of India repeatedly notes district-level alerts in Tamil Nadu (yellow alert) and details expected thunderstorms and wind gusts. Business Line adds more of the meteorological mechanism, while some Times of India headlines also contrast south India’s wet conditions with drier weather or calmer periods in Delhi-NCR and the northeast.
