On Sunday, Chennai residents woke up to overcast skies and occasional drizzles, offering brief respite from the heat. The maximum temperature is forecasted to hover between 33 and 34 degrees Celsius, while the minimum will likely stay steady around 27–28 degrees Celsius. The city can expect similar weather through the week, with light rainfall predicted on April 6, 8, 9, and 12. However, no significant weather warnings have been issued for Chennai itself.
Heavy Rain and Yellow Alerts in Western Ghats While Chennai sees relatively milder conditions, other districts in the state are on higher alert. The RMC has issued a yellow alert for the Ghat regions of Coimbatore and the districts of Nilgiris, Theni, Dindigul, and Tenkasi. These areas could experience heavy rainfall, thunderstorms, lightning, and gusty winds, particularly on Sunday and Monday. On April 5, southern Tamil Nadu witnessed widespread showers, with Kozhiporvilai in Kanyakumari recording an impressive 19 cm of rainfall, and Tirupur North not far behind with 11 cm.
Cyclonic Circulation Driving the Weather The current unstable weather is being driven by a cyclonic circulation up to 3.1 km above mean sea level, accompanied by a trough stretching from Central Maharashtra to North Tamil Nadu via Interior Karnataka, as per reports. Additionally, a low-pressure trough over the southeast Bay of Bengal and adjoining areas is fueling the rainfall activity. Although the earlier cyclonic circulation over Tamil Nadu has weakened, the influence of this new system is set to continue into early next week.
