The Chilean Navy has issued a warning for possible formation of sea tornadoes this Sunday, affecting coastal and oceanic areas across five regions in central-southern Chile. The alert covers zones from the Maule Region to Los Ríos, including Ñuble, Biobío, and La Araucanía. The advisory was released by the Talcahuano Regional Marine Weather Center, which cited atmospheric instability leading to convective cloud formations that could create favorable conditions for these phenomena. The warning is valid from midnight to 3 p.m. local time on Sunday, September 20. It includes both the coastline and the oceanic area off the aforementioned regions.
