DISCUSSION AND OUTLOOK ---------------------- At 800 PM MST (0300 UTC), the center of Tropical Storm Ileana was located near latitude 25.5 North, longitude 109.0 West. Ileana is drifting toward the north near 2 mph (4 km/h). A turn toward the northwest is expected soon with an increase in forward speed. On the forecast track, the center of Ileana will move near, or over the coastal region of northern Sinaloa during the next several hours, and then move over the Gulf of California roughly parallel to the coast on Sunday. Maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Weakening is forecast to begin overnight, and Ileana is likely to degenerate into a remnant low on Sunday. The remnant low is expected to dissipate by Monday. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The Mexican Navy station at Topolobampo recently reported sustained winds of 45 mph (72 km/h) and a wind gust of 58 mph (93 km/h). The estimated minimum central pressure is 1000 mb (29.53 inches).
