DISCUSSION AND OUTLOOK ---------------------- At 800 AM MST (1500 UTC), the center of Tropical Storm Lorena was located near latitude 24.2 North, longitude 114.2 West. Lorena is moving toward the northwest near 8 mph (13 km/h). A turn toward the north and a decrease in forward speed is expected tonight. On the forecast track, the center of Lorena is expected to move generally parallel to the west coast of the Baja California peninsula through tonight, and could move closer to the west-central coast of the Baja California peninsula while it weakens on Friday. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Lorena is expected to quickly weaken for the next couple of days, and it is forecast to degenerate into a remnant low near or to the west of the Baja California peninsula by Friday night. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 991 mb (29.27 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 Sonora Mexico through Friday. Additional rainfall totals of 4 to 8 inches, with maximum storm total amounts of 15 inches, are possible across portions of Baja California Sur, far southeast Baja California and southwestern Sonora into Friday. This will bring the risk of life-threatening flash floods and mudslides, especially in areas of higher terrain. Elsewhere across Mexico, 2 to 4 inches of rain, with isolated totals up to 6 inches, are expected across the remainder of Sonora and northern Sinaloa. These amounts will lead to isolated to scattered instances of flash flooding. Across the southwestern United States, 1 to 3 inches of rain, with isolated totals up to 5 inches, are expected across portions of Arizona and New Mexico through Saturday, 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, mainly in gusts, are expected somewhere within the warning area in Baja California Sur today through 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.
