Weather conditions are set to shift as a north-south trough extending toward the Comorin region continues to influence the state. This system, combined with land heating and moisture inflow from both the Bay of Bengal and the Arabian Sea, is likely to trigger rainfall. Districts such as Karur, Erode, and the Nilgiris are expected to receive heavy showers, particularly through May 10, with interior and Western Ghats regions seeing the most impact.
