DISCUSSION AND OUTLOOK ---------------------- At 700 AM CDT (1200 UTC), the center of Tropical Storm Ileana was located near latitude 15.7 North, longitude 101.2 West. Ileana is moving toward the northwest near 17 mph (28 km/h) and this general motion is expected to continue into Wednesday. On the forecast track, Ileana's center is forecast to move parallel to and just offshore of the coast of southwestern Mexico through Tuesday. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Strengthening is expected during the next day or so, and Ileana is forecast to become a hurricane by Tuesday morning. Gradual weakening is expected to begin Tuesday night, and Ileana is forecast to dissipate by Wednesday afternoon or evening due to its proximity to the much larger Tropical Storm or Hurricane John located to its southwest. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are possible in the watch area tonight and early Tuesday. Tropical storm conditions are expected within the warning area late today through early Tuesday. Tropical storm conditions are possible within the watch area over southern Baja California Sur Wednesday morning. RAINFALL: Ileana is expected to produce total rain accumulations of 2 to 4 inches over coastal sections of the Mexican states of Guerrero, Michoacan, Colima, and Jalisco, with possible isolated maximum amounts of 6 inches through Tuesday night. These rains may cause flash flooding. SURF: Swells generated by Ileana will be affecting portions of the coast of southwestern Mexico during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
