DISCUSSION AND OUTLOOK ---------------------- At 800 AM MST (1500 UTC), the center of Hurricane Lorena was located near latitude 22.3 North, longitude 111.6 West. Lorena is moving toward the northwest near 16 mph (26 km/h), and this motion with a decrease in forward speed is expected through early Thursday. A generally slow northward motion is expected late Thursday and early Friday, with a gradual turn toward the northeast by late 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 and then approach the coast late Thursday through Friday. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Rapid strengthening is forecast to continue through this evening. Fast weakening is expected to begin on Thursday, and Lorena could weaken back to a tropical storm by Friday. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 70 miles (110 km). The estimated minimum central pressure is 988 mb (29.18 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 southeastern Baja California and 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, far southeast Baja California and southwestern Sonora through Friday. This will bring the risk of life-threatening flash floods and mudslides, especially in areas of higher terrain. Within the moisture surge ahead of Lorena, 1 to 3 inches of rain, with localized totals up to 4 inches, are expected from the Mexico states of Sinaloa northward into Arizona through Friday, bringing the potential for isolated to scattered flash flooding. For a complete depiction of forecast rainfall and flash flooding associated with 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 spreading 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 north of Punta Abreojos Thursday night and early Friday. 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.
