DISCUSSION AND OUTLOOK ---------------------- At 900 PM MDT (0300 UTC), the center of Tropical Storm Iselle was located near latitude 21.8 North, longitude 114.2 West. Iselle is moving toward the north-northeast near 9 mph (15 km/h). A turn toward the north is expected overnight and this general motion should continue through Sunday, followed by a turn to the northwest. Maximum sustained winds have decreased to near 40 mph (65 km/h) with higher gusts. Iselle is expected to weaken to a depression overnight, and to degenerate into a remnant low within the next day or so. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 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 couple of days and will likely cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
