DISCUSSION AND OUTLOOK ---------------------- At 800 AM PDT (1500 UTC), the center of Tropical Storm Iselle was located near latitude 18.3 North, longitude 115.3 West. Iselle is moving toward the northeast near 5 mph (7 km/h) and this general motion is expected to continue through tonight. A northward turn is expected by Saturday morning followed by a northwestward motion on Sunday evening. Afterward, Post-Tropical/Remnant Low Iselle is forecast to turn west-northwestward in the low-level easterly flow. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Some fluctuations in strength are possible today, but a gradual weakening trend should commence later tonight. An observing site at Clarion Island, MX recently reported a sustained wind of 39 mph (65 km/hr) and a gust of 47 mph (80 km/hr). Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Iselle and a large area of southwesterly winds to its south are affecting portions of the southwestern coast of Mexico. These swells are expected to spread northward along the coast of west-central Mexico and the southern Baja California peninsula through Sunday, and will likely cause life-threatening surf and rip current conditions.
