Reasons Behind the Rainfall
The forecasted rainfall is attributed to a north-south trough extending from North Interior Karnataka to South Tamil Nadu at an altitude of 1.5 km above mean sea level. The weather department also noted that there will be no significant change in maximum temperatures until Sunday. However, temperatures are expected to rise by 2–3 degrees Celsius in isolated pockets of the state on Monday and Tuesday.
Rainfall Statistics and Impact
On Saturday, Erode recorded the highest maximum temperature at 38°C. Meanwhile, the southern parts of Tamil Nadu witnessed unseasonal rainfall, helping to lower temperatures in those regions.
