TROPICS: In the eastern Pacific, Polo is forecast to approach the west coast of the Baja California peninsula tomorrow as a hurricane, and a Hurricane Warning is in effect for that region.
Tropical storm conditions could reach portions of the coast as soon as tonight or early tomorrow, making further preparations difficult. These conditions will
likely spread across Baja California through tomorrow and into mainland Mexico on early Tuesday. A storm surge is likely, especially in areas of onshore winds.
Heavy rainfall associated with Polo may begin to impact Baja California Sur later tonight into Tuesday and portions of Sonora late tomorrow into Tuesday. This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain.
Moisture from Polo will support heavy rainfall and flooding potential across the Southwest U.S. into the Southern High Plains late tomorrow into Tuesday.
