Additional watches or warnings may be required later today. At 500 AM EDT (0900 UTC), the center of Hurricane Isaias was located near latitude 23.9 North, longitude 77.1 West. Isaias is moving toward the northwest near 12 mph (19 km/h), and a general northwestward motion with some decrease in forward speed is expected for the next day or so, followed by a turn toward the north-northwest by late Sunday. On the forecast track, the center of Isaias will move near or over the Central Bahamas this morning, near or over the Northwestern Bahamas later today and near the east coast of the Florida peninsula tonight through Sunday. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Little change in strength is expected through Sunday, and and Isaias is forecast to remain a hurricane during this time. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 988 mb (29.18 inches). WIND: Hurricane conditions are occurring over portions of the Central Bahamas and will spread over the Northwestern Bahamas later today. Hurricane conditions are expected to reach the coast within the hurricane warning area in Florida tonight and will spread northward through Sunday. Winds are expected to first reach tropical storm strength later today, making outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. Tropical storm conditions are expected within the tropical storm warning area, and are possible within the watch area, over southern Florida by this afternoon or evening.
