Florence is moving toward the west near 6 mph (9 km/h), and this general motion is expected to continue today. A west-northwestward motion with an increase in forward speed is expected by Monday, and that motion is forecast to continue through mid-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. Aircraft data indicate that maximum sustained winds have increased to near 75 mph (120 km/h) with higher gusts. Florence is forecast to rapidly strengthen to a major hurricane by Monday, and is expected to remain an extremely dangerous major hurricane through Thursday. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 115 miles (185 km). The latest minimum central pressure reported by a NOAA Hurricane Hunter Aircraft is 984 mb (29.06 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Florence are affecting Bermuda and are beginning to reach portions of the U.S. East Coast. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
