High-period swell waves reached the southern tip of India on Saturday, interacting with coastal regions in Keralam. The Kerala State Disaster Management Authority (KSDMA) reported swell waves of 20 to 24 seconds in period and up to 1.5 meters in height hitting Kanyakumari. Precursor waves began reaching Keralam coast. Swell surge impact is expected to worsen from Saturday night, especially during high tide.
The system will continue interacting with coastline until 2:30 a.m. on September 28, with potential inundation in low-lying coastal areas. A red alert is in place along Keralam coast, suspending recreational and fishing activities until September 28. The Indian National Centre for Ocean Information Services (INCOIS) issued a swell surge warning for Keralam, southern Tamil Nadu and Lakshadweep from September 26 to 28.
These long-period swells combined with high tide may cause coastal flooding in Keralam, southern Tamil Nadu, and Lakshadweep during the forecast period.
