DISCUSSION AND OUTLOOK ---------------------- At 800 PM PDT (0300 UTC), the center of Tropical Storm Iselle was located near latitude 19.3 North, longitude 115.2 West. Iselle is moving toward the north-northeast near 6 mph (9 km/h), and this general motion is expected to continue through early Saturday. A turn toward the north at a faster forward speed is expected on Saturday, followed by a north-northwestward motion Saturday night through Monday. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Weakening is forecast during the next few days, and Iselle is expected to become a tropical depression Saturday night. The depression should then degenerate into a remnant low on Sunday. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 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 and west-central coast of Mexico, as well as the west coast of Baja California Sur. These swells are expected to continue for the next few days and will likely cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
