On the forecast track, the center of Genevieve is expected to move parallel to but well offshore the coast of southwestern Mexico during the next few days. Maximum sustained winds have increased to near 65 mph (100 km/h) with higher gusts. Rapid strengthening is anticipated during the next couple of days, and Genevieve is forecast to become a hurricane later today and a major hurricane by Tuesday. Tropical-storm-force winds extend outward up to 125 miles (205 km) from the center. The estimated minimum central pressure is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Large swells produced by Genevieve will begin affecting portions of the southern coast of Mexico today and will spread northward along the southwestern and west-central coast of Mexico to the Baja California peninsula through Wednesday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
