Some slight additional strengthening is expected tonight or Saturday morning followed by gradual weakening through early next week. Isaac is expected to be a post-tropical cyclone on Monday. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km). The estimated minimum central pressure is 976 mb (28.82 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Isaac and a large wind fetch from a deep-layer trough could spread into the Azores by this weekend.
