Tamil Nadu Weather Update: Low Pressure Area Forms Over Bay of Bengal; Heavy Rain Likely Till May 16
After experiencing intense summer heat over the past few weeks, several parts of Tamil Nadu have started receiving rainfall, bringing relief from soaring temperatures. The recent showers have led to a noticeable change in weather conditions across the state.
