Hurricane and tropical storm conditions will spread into mainland Mexico late tonight and early Tuesday. A dangerous storm surge is expected in areas of onshore winds. 2. Heavy rainfall associated with Polo will impact Baja California Sur along with southern and central portions of Sonora tonight and Tuesday. This rainfall is expected to 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 tonight into Tuesday. 3. Even after Polo dissipates, its mid-level remnants may produce strong gusty winds well inland over the higher terrain of northwest Mexico, southern New Mexico, and far western Texas.
