DISCUSSION AND OUTLOOK ---------------------- At 1100 AM MST (1800 UTC), the center of Tropical Storm Ileana was located near latitude 22.4 North, longitude 109.3 West. Ileana is moving toward the north-northwest near 8 mph (13 km/h). A slower north-northwestward to northward motion is expected during the next few days. On the forecast track, Ileana is expected to move across the southern portion of the Baja California peninsula this afternoon and over the southern and central Gulf of California this weekend. Recently-received satellite wind data indicate that 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 Monday. Tropical-storm-force winds extend outward up to 60 miles (95 km) to the east of the center. The estimated minimum central pressure is 999 mb (29.50 inches).

RAINFALL: Through this weekend, Tropical Storm Ileana may produce rainfall of 4 to 6 inches, with localized higher amounts up to 8 inches, across southern Baja California. For northwest coastal Sinaloa, Tropical Storm Ileana may result between 6 to 8 inches with localized higher amounts up to 12 inches.

Tropical storm conditions are possible within the watch area by early Saturday.
