The ongoing spell of rainfall over southern parts of India is expected to continue until January 9. Indian Meteorological Department (IMD) director C.S. Patil stated that Many districts across the southern state will receive moderate to heavy rains over the next three days due to cyclonic circulation and a low-level trough over the Arabian Sea on the west and Bay of Bengal on the east.

A trough in low-level easterlies runs from the east-central Arabian Sea off Karnataka coast to south Madhya Maharashtra, as stated by the India Meteorological Department (IMD). This active easterly wave spell is set to cause scattered to fairly widespread rains, thunderstorms, and lightning over southern peninsular India during the next 4-5 days. The forecast adds that isolated heavy rainfall is possible over Tamil Nadu, Puducherry, Karaikal, Kerala, and Mahe until January 9.
