South India prepares for Northeast Monsoon onset

Northeast Monsoon heavy rainfall cyclonic circulation weather forecast South India

The Northeast Monsoon is expected to arrive in South India, specifically impacting Tamil Nadu, Puducherry, and Kerala, around October 15. The India Meteorological Department (IMD) has forecasted unsettled weather due to the formation of a low-pressure area over the South Andaman Sea and cyclonic circulation over the Gulf of Mannar and the Bay of Bengal.

In Tamil Nadu, heavy rainfall and gusty winds reaching 40–50 km/h are predicted for several districts, including Nilgiris, Coimbatore, Erode, and Kanyakumari. Coastal areas such as Chennai are also expected to experience rain and thunderstorms. While some northern inland areas may see a temporary rise in temperature, widespread precipitation is anticipated to intensify by mid-week.

Kerala is also bracing for the monsoon transition, with the IMD predicting light to moderate rainfall across the state from October 12 to October 16, with isolated heavy spells expected between October 15 and 16. Authorities have advised residents to remain alert to lightning and potential waterlogging in low-lying areas.
