But weather models missed the rare and rapid intensification that Otis was undergoing, just two weeks after a similar intensification occurred with Hurricane Lidia impacting the outskirts of Puerto Vallarta. Unlike Lidia, Otis was aimed directly at Acapulco, a city of 1 million people. The Mexican National Weather Service, in coordination with the National Hurricane Center, promptly issued hurricane and tropical storm warnings from Lagunas de Chahua, Oaxaca to Punta Maldonado, Guerrero — about a 60-mile stretch of south-facing coastline — for Tuesday night.
