A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. Interests elsewhere in Baja California Sur should monitor the progress of this system. Additional watches or warnings may be required later tonight. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 300 PM MDT (2100 UTC), the center of Tropical Storm Olaf was located near latitude 19.4 North, longitude 107.7 West. Olaf is moving toward the northwest near 6 mph (9 km/h). This general motion along with an increase in forward speed are expected through Friday. A turn toward the west-northwest is forecast by Friday night, followed by a turn toward the west on Saturday. On the forecast track, the center of Olaf will move just to the southwest of southern Baja California Sur on Thursday and Friday. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Additional strengthening is forecast during the next day or so, and Olaf could be near hurricane strength by late Thursday. The storm is expected to begin weakening on Friday. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm Olaf can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC and on the web at hurricanes.gov/graphics_ep5.shtml?key_messages WIND: Hurricane conditions are possible within the Hurricane Watch area in Baja California Sur Thursday night. Tropical storm conditions are expected in the Tropical Storm Warning area in Baja California Sur by late Thursday or Thursday night. RAINFALL: Olaf is expected to produce total rainfall amounts of 3 to 6 inches with maximum amounts of 10 inches across portions of far southern Baja California Sur Thursday through Friday. This rainfall may trigger flash flooding and mudslides. SURF: Olaf is expected to generate swells that will affect portions of the coasts of Baja California Sur and Sinaloa by Thursday, spreading northward along the west coast 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. NEXT ADVISORY ------------- Next intermediate advisory at 600 PM MDT. Next complete advisory at 900 PM MDT. $$ Forecaster Latto
