On the forecast track, Pamela will pass south of the southern tip of the Baja California peninsula Tuesday night or early Wednesday and approach the coast of west-central mainland Mexico on Wednesday. Maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts. Pamela is forecast to be a hurricane by late tomorrow, and could be a major hurricane on Wednesday. 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 ---------------------- SURF: Pamela is expected to generate swells that will affect portions of the southern Baja California peninsula and southwestern and west-central mainland Mexico by late Tuesday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
