In Mexico, a hurricane watch was issued in Baja California where rough seas, scattered showers and thunderstorms are in the forecast for Saturday.

A hurricane prevention zone has been established from north of Punta Abreojos to Punta Eugenia in Baja California Sur, the Mexican secretary of the environment said Friday. Ships are urged to take \"extreme precaution\" due to the strong winds and high waves forecast for the area.

A tropical storm warning is in effect for Cabo San Lucas. Hilary's outer bands could graze the popular resort town but it is not forecast to directly hit Cabo.

ABC News' Anne Laurent, Samira Said, Tristan Maglunog and Ellie Kaufman contributed to this report.
