Hurricane Florence Batters the East Coast

According to the the National Hurricane Center (NHC), Hurricane Florence is a Category 1 storm on the Saffir-Simpson Scale and is expected to remain a hurricane throughout the day as it moves further inland. The NHC anticipates that the storm will continue to slow as it moves westward and has cautioned that the storm brings catastrophic flooding and life-threatening storm surge that will linger long into the weekend and early next week. The storm has knocked out power for over 600,000 customers in North Carolina and over 70,000 customers South Carolina as of the time of this post, with the numbers expected to continue climbing. The National Weather Service cautions that “this storm will be a marathon versus a sprint.”

With the NHC reporting storm surges potentially reaching as high as 11 feet and rainfall predicted to reach up to 40 inches in some areas, flood waters pose a very serious threat for those impacted by Hurricane Florence. The Centers for Disease Control (CDC) and the Environmental Protection Agency (EPA) caution the dangers and hazards posed by both moving and standing flood waters.

HAZARDS 

Per the NHC’s 2:00 pm EDT update, below is a list of hazards affecting land as a result of the ongoing storm:

STORM SURGE:  The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline.  The water has the potential to reach the following heights above ground…

  • Cape Fear NC to Cape Lookout NC…7-11 ft, with locally higher amounts in the Neuse, Pamlico, Pungo, and Bay Rivers
  • Cape Lookout NC to Ocracoke Inlet NC…6-9 ft
  • South Santee River SC to Cape Fear NC…4-6 ft
  • Ocracoke Inlet NC to Salvo NC…4-6 ft
  • Salvo NC to Duck NC…2-4 ft
  • Edisto Beach SC to South Santee River SC…2-4 ft

RAINFALL: Florence is expected to produce heavy and excessive rainfall in the following areas:

  • Southeastern coastal North Carolina into far northeastern South Carolina…an additional 20 to 25 inches, with isolated storm totals of 30 to 40 inches. This rainfall will produce catastrophic flash flooding and prolonged significant river flooding.
  • Remainder of South Carolina and North Carolina into southwest Virginia: 5 to 10 inches, isolated 15 inches. This rainfall will produce life-threatening flash flooding.
  • Rainfall totals exceeding 14 inches thus far have been reported at several locations across southeastern North Carolina.

TORNADOES:  A few tornadoes are possible in eastern North Carolina today.

SURF:  Swells generated by Florence are affecting Bermuda, portions of the U.S. East Coast, and the northwestern and central Bahamas. These swells are likely to cause life-threatening surf and rip current conditions.

Hagerty will continue to monitor Florence’s movements and provide critical updates on Disaster Discourse. If you are in an area impacted by the storm, please remain safe and heed guidance from your state and local officials.
