The onset of the northeast monsoon is a key factor behind the changing weather conditions across southern India. The IMD announced that the southwest monsoon had withdrawn from the entire country on October 15, while northeast monsoon rainfall activity began over Tamil Nadu, Puducherry, Karaikal, coastal Andhra Pradesh, Rayalaseema, south interior Karnataka and Kerala.
The seasonal shift is particularly significant for Tamil Nadu, where the northeast monsoon contributes a substantial share of annual rainfall. With rain warnings in place across parts of Tamil Nadu and Andhra Pradesh, residents should keep track of district-level forecasts and alerts over the coming days.
