Due to extremely heavy rainfall over Tirunelveli and adjoining Tenkasi districts, the Kalakkad Mundanthurai Tiger Reserve (KMTR) authorities banned entry to Manimuthar waterfalls as the water cascaded in high volume and the terrain became dangerous for visitors. With Papanasam and Manimuthar dams receiving huge inflows, reservoir levels rose significantly. The torrential downpours also triggered flooding in low-lying residential areas like Ambasamudram and Kallidaikurichi, isolating some localities and causing officials to declare a school and college holiday to safeguard residents. Along with Manimuthar, entry restrictions were also applied at Courtallam waterfalls and other popular spots to ensure public safety during the intense rainfall.
