Overview

• NHC advisories on Wednesday report Priscilla down to Category 1 strength with roughly 80 mph winds, moving parallel to Baja California Sur and forecast to keep weakening over cooler waters.
• A tropical storm watch remains in effect from Cabo San Lucas to Cabo San Lázaro, with large swells producing life‑threatening surf and rip currents along parts of western Mexico and southern Baja.
• Moisture tied to Priscilla is projected to spread north beginning Thursday, bringing rounds of thunderstorms and locally heavy rain across Arizona, New Mexico, Southern California, southern Nevada, Utah and western Colorado into the weekend.
• Weather Prediction Center outlooks highlight the Four Corners for elevated flash‑flood potential Friday into Saturday, and meteorologists note some locations could receive more than an October’s worth of rain in a few days.
• Authorities in Baja California Sur canceled classes in Los Cabos and La Paz and opened shelters, and U.S. forecasters urge residents in vulnerable areas to monitor updates given uncertainty in exact timing and rainfall totals.
