DISCUSSION AND OUTLOOK ---------------------- At 1100 AM MST (1800 UTC), the eye of Hurricane Polo was located by NOAA Hurricane Hunter aircraft near latitude 21.3 North, longitude 114.0 West. Polo is moving toward the north-northwest near 12 mph (19 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 are near 125 mph (205 km/h) with higher gusts. Polo is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Fluctuations in strength are possible over the next day or two, but Polo is forecast to remain a strong hurricane when it reaches 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 105 miles (165 km). The minimum central pressure estimated by dropsonde data is 950 mb (28.06 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 and eastward across Baja California Sur on Monday. Hurricane conditions are possible within the Hurricane Watch area in mainland northwestern Mexico Monday night and Tuesday. RAINFALL: Polo is expected to produce rainfall totals of 4 to 8 inches with maximum amounts of 12 inches across portions of Baja California Sur. Rainfall totals of 4 to 6 inches with maximum totals of 8 expected across portions of Sonora. 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.
