Florence lashes the Southeast Coast

Florence, now downgraded to a Category 2 Hurricane, has grown into a broad storm with hurricane or tropical storm force winds stretching across 400 miles.  The outer bands have come ashore in eastern North Carolina this morning, igniting tornadic thunderstorms and producing heavy, wind-swept rain.

Due to "blocking highs" to its north and northwest, Hurricane Florence is expected to stall near the Coast and then drift southwestward along the southeastern coast of North Carolina and the northeastern coast of South Carolina, perhaps as far south as Charleston.  North of the storm's eyewall, which currently has sustained winds of 105 mph, onshore winds will produce a storm surge of 10 feet or more, as well as inland flooding from up to 2 feet or more of rain.

Due to its slow forward motion (toward the coast and then down the coast), the high winds, storm surge and heavy rain will persist for a long period of time (perhaps 48 hours), increasing the risk of flooding and damage to trees, power lines and structures.  Of course, the Hurricane Stuntmen will be there to bring us the action.
