The heavy rainfall poses risks of flooding in low-lying areas and increased water levels in rivers such as Moyar, Bhavani, and Noyyal. Reservoirs, including Pechiparai and Papanasam, may see higher inflows. Districts like Kanniyakumari, the Nilgiris, and Coimbatore are particularly vulnerable, with isolated very heavy rainfall and squally winds of up to 50 km/h expected. The rainfall could disrupt daily life, including transportation and agricultural activities, in the affected regions.
