A weather trough stretching from interior Tamil Nadu to the Konkan region is shaping current conditions. On April 3 and 4, light to moderate rain with thunderstorms is expected mainly in south coastal districts and along the Western Ghats, while most other areas stay dry.
From April 5 onward, rainfall is likely to spread to more regions, including Puducherry and Karaikal. By April 7 and 8, scattered showers with thunderstorms may occur across coastal and hilly areas, though several interior districts could still experience dry spells in between.
