DISCUSSION AND OUTLOOK ---------------------- At 500 PM MST (0000 UTC), the center of Hurricane Lorena was located near latitude 23.1 North, longitude 112.9 West. Lorena is moving toward the northwest near 12 mph (19 km/h), and this motion with an additional decrease in forward speed is expected through early Thursday. A generally slow northward motion is expected late Thursday and Thursday night, with a gradual turn toward the northeast on Friday. On the forecast track, the center of Lorena is expected to move parallel to the west coast of the Baja California peninsula through tonight, approach the coast of Baja California Sur Thursday night, and move inland over the Baja California peninsula on Friday. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Some strengthening is possible through this evening. Fast weakening is expected to begin on Thursday, and Lorena is expected to weaken to a tropical storm by Friday morning. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 80 miles (130 km). The estimated minimum central pressure is 985 mb (29.09 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Lorena can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP2 and WMO header WTPZ42 KNHC. RAINFALL: Bands of heavy rainfall will continue to impact Baja California Sur and move into southwestern Sonora by Thursday, with this rainfall potentially persisting through Friday. Rainfall totals of 5 to 10 inches, with maximum amounts of 15 inches, are possible across portions of Baja California Sur and southwestern Sonora through Friday. This will bring the risk of life-threatening flash floods and mudslides, especially in areas of higher terrain. Farther northeast, 1 to 3 inches of rain, with localized totals up to 5 inches, are expected from portions of the Mexico states of Sinaloa north and northeast into portions of Arizona and southern New Mexico through Saturday afternoon, bringing the potential for isolated to scattered flash flooding. For a complete depiction of forecast rainfall and flash flooding associated with Hurricane Lorena, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_ep2.shtml?rainqpf WIND: Tropical storm conditions are expected in the warning area beginning tonight and will spread northward within the warning area in Baja California Sur through Thursday and into Friday. Tropical storm conditions are possible within the watch area south of Santa Fe through tonight, and in the watch area on the east coast of the Baja California peninsula Friday into Friday night. STORM SURGE: Coastal flooding from storm surge is likely along the coast of Baja California Sur near and to the right of where Lorena makes landfall. SURF: Swells generated by Lorena will continue affecting portions of the south and west coasts of Baja California Sur through Friday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
