DISCUSSION AND OUTLOOK ---------------------- At 200 AM MST (0900 UTC), the center of Hurricane Polo was located near latitude 20.3 North, longitude 113.6 West. Polo is moving toward the north-northwest near 10 mph (17 km/h). A turn toward the north is expected later today, followed by a turn toward the northeast on Monday. On the forecast track, Polo is expected to approach the west coast of Baja California Sur on Monday, move across the peninsula Monday night and then approach northwestern mainland Mexico by early Tuesday. Maximum sustained winds remain near 120 mph (195 km/h) with higher gusts. Polo is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Additional weakening is expected during the next few days, but Polo is forecast to remain a hurricane when it approaches Baja California Sur on Monday. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). The estimated minimum central pressure is 952 mb (28.12 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Polo can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP2 and WMO header WTPZ42 KNHC. WIND: Hurricane conditions are expected within the warning area along the west coast of Baja California Sur by Monday afternoon, with tropical storm conditions possible in the southern portion of the warning area by tonight into early Monday. These conditions are expected to spread northward during the day on Monday and then eastward across Baja California Sur by Monday evening. Hurricane conditions are possible within the Hurricane Watch area in mainland northwestern Mexico on Tuesday. RAINFALL: Polo is expected to produce rainfall totals of 4 to 8 inches with maximum amounts of 10 inches across portions of Baja California Sur. This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain. For a complete depiction of forecast rainfall associated with Polo, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_ep2.shtml?rainqpf SURGE: A storm surge could produce significant coastal flooding in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Polo will continue affecting the coast of southwestern Mexico, west-central Mexico, and Baja California Sur during the next couple of days. These swells will spread northward along the coast of the Baja California Peninsula through the remainder of the weekend. These swells are likely to cause life-threatening surf, rip currents, and coastal flooding. Please consult products from your local weather office.
