The Meteorological Centre has predicted moderate rainfall across Tamil Nadu starting April 13, lasting for seven days. Intermittent showers are expected in select areas, particularly in Ramanathapuram district and the coastal Delta region, while much of the state and the Union Territory of Puducherry will remain dry. A low-pressure trough at approximately 0.9 km above sea level is influencing this weather pattern, extending from northeastern Bihar to southern Tamil Nadu. The trough is expected to enhance localized cloud development, resulting in scattered rainfall along its path. Additionally, daytime temperatures in the interior districts are forecasted to rise by 2-3°C from April 13 to 17, potentially exceeding seasonal averages. In contrast, coastal regions and Puducherry are likely to maintain stable temperatures. The Meteorological Centre has indicated that no advisories for fishermen have been issued, suggesting calm sea conditions along the coast.
