DISCUSSION AND OUTLOOK ---------------------- With the help of Mexican Navy automatic weather stations, at 100 AM CDT (0600 UTC), the center of Hurricane Lorena was located near latitude 19.3 North, longitude 104.9 West. Lorena is moving toward the northwest near 12 mph (19 km/h), and the forward speed is expected to decrease a bit on Thursday. On the forecast track, the center of Lorena will continue moving near or over the southwestern coast of Mexico within the hurricane warning area on Thursday. Lorena is then expected to move west-northwestward away from the west-central coast of Mexico late Thursday and Friday and approach southern Baja California Sur Friday night and Saturday. Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Additional strengthening is forecast during the next couple of days. However, if the center deviates a little to the right and interacts with the high terrain, weakening could then occur. Hurricane-force winds extend outward up to 15 miles (30 km) from the center, and tropical-storm-force winds extend outward up to 90 miles (150 km). A Mexican Navy automatic weather station located near Manzanillo reported a wind gust of 52 mph (83 km/h) when the center of Lorena moved nearby. The estimated minimum central pressure is 990 mb (29.24 inches).
