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. 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).
