Now a tropical depression, Florence hovered primarily over North and South Carolina over the weekend, dumping record-breaking rainfall in those states and killing at least 17 people. Remnants of the system are heading north, bringing rain through Tuesday.

The storm made landfall near Wrightsville Beach, N.C. on Sept. 14, causing more than one million power failures and at least 16 deaths over the weekend, according to the New York Times. Tropical Depression Florence slowly flooded cities, endangering communities from the coastline to the mountains, and requiring more than 1,000 rescues.

Karen Clark & Company (KCC) estimates that insured losses from Hurricane Florence will be $2.5 billion, which includes the privately insured wind, storm surge, and inland flooding damage to residential, commercial, and industrial properties and automobiles, but does not include National Flood Insurance Program losses.

KCC reports:

On Sept. 14, Florence made landfall in North Carolina with maximum sustained wind speeds around 90 mph. As the storm slowly passed southwest over South Carolina on Sept. 15, the hurricane weakened to a tropical storm and made a wide turn to the north. By Sept. 16, Florence had become a tropical depression in northeastern South Carolina.

Peak surge from Hurricane Florence reached 10 feet in New Bern, North Carolina, and other areas of the state including Beaufort and Wilmington had significant storm surge impacts. Locations at the heads of shallow bays, where the water is more easily pushed ashore by a hurricane’s high wind speeds, experienced the most coastal inundation.

Although this storm is winding down, there may be more to come. “We’re now in the peak of hurricane season, and the season still has a long way to go,” Dr. Gerry Bell, lead seasonal hurricane forecaster for the National Oceanic and Atmospheric Administration told the Times. He added, “There will be more storms—that’s a definite. Where exactly they track, and when or if they’ll make landfall—that’s what’s not predictable this far in advance.”
