A circulation system goes through a sequence of stages as it intensifies into a mature tropical cyclone. Tropical cyclones cannot suddenly appear on their own. Ample atmospheric moisture combined with strong upward lift from the anticyclone atop Florence yielded an environment conducive to widespread torrential precipitation. [13] On September 5, the tropical cyclone reached an initial peak intensity with 1-minute sustained winds of 130mph (215km/h) with a central pressure of 950 millibars (28inHg), making it as a Category4 hurricane on the SaffirSimpson scale. Environmental conditions became increasingly conducive to reorganization on September8 as NOAA Hurricane Hunters began reconnaissance of the cyclone, with the shear decreasing and warm waters becoming deeper. Moderate rain with localized areas of heavy precipitation extended into Pennsylvania, New York, and southern New England on September18. [48] Florence's forward motion slowed throughout the day as the ridge steering it northwest built ahead of the cyclone toward the Appalachian Mountains. Once over land, the forward motion of the hurricane slowed to about 2 to 3 miles per hour. Three nearby dams failed, causing significant flooding in Cheraw and the town of Chesterfield.
