DISCUSSION AND OUTLOOK ---------------------- At 900 PM GMT (2100 UTC), the center of Hurricane Isaac was located near latitude 41.3 North, longitude 38.4 West. Isaac is moving toward the northeast near 18 mph (30 km/h). A slower east-northeast to northeast motion is expected during the next couple of days. Maximum sustained winds are near 100 mph (155 km/h) with higher gusts. Gradual weakening is expected, and Isaac is forecast to be a post-tropical cyclone on Monday. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km). The estimated minimum central pressure is 968 mb (28.59 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Isaac and a large wind fetch from a deep-layer trough will affect the Azores over the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
