On the forecast track, Ileana is expected to move across the southern portion of the Baja California peninsula today and over the Gulf of California this weekend. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Little change in strength is forecast before Ileana reaches the Baja California peninsula. Weakening is expected over the weekend, and Ileana is forecast to dissipate by early Monday. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure is 999 mb (29.50 inches).
