DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Tropical Storm Florence was located near latitude 24.5 North, longitude 54.3 West. Florence is moving toward the west near 7 mph (11 km/h), and this general motion is expected to continue during the next couple of days. A west-northwestward to northwestward motion with an increase in forward speed is expected by the middle of next week. On the forecast track, the center of Florence will move over the southwestern Atlantic Ocean between Bermuda and the Bahamas Tuesday and Wednesday, and approach the southeastern U.S. coast on Thursday. Maximum sustained winds remain near 65 mph (100 km/h) with higher gusts, but Florence is likely to restrengthen to a hurricane by tonight. Rapid intensification is expected to start on Sunday, and Florence is forecast to be a major hurricane by Tuesday. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 995 mb (29.39 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Florence are affecting Bermuda and will reach portions of the U.S. East Coast over the weekend. These swells are likely to cause life-threatening surf and rip current conditions.
Key Messages: 1. Florence is forecast to be a dangerous major hurricane near the southeast U.S. coast by late next week, and the risk of direct impacts continues to increase. However, given the uncertainty in track and intensity forecasts at those time ranges, it's too soon to determine the exact timing, location, and magnitude of those impacts. 2. Interests along the U.S. East Coast, particularly from north Florida through North Carolina, should closely monitor the progress of Florence, ensure they have their hurricane plan in place, and follow any advice given by local officials. 3. Large swells are affecting Bermuda and will begin to affect portions of the U.S. East Coast this weekend, resulting in
life-threatening surf and rip currents.
