Hurricane Florence

The storm

Florence left the Cape Verde islands August 31, 2018, and peaked at Category 4 — about 150 mph — on September 11 while pointed at the Carolinas. More than a million people were ordered to evacuate coastal North Carolina, South Carolina, and Virginia.

Wind shear then cut the storm to Category 1, but the dangerous trade was already underway: the wind field grew and the forward speed collapsed. Florence made landfall at Wrightsville Beach, North Carolina, on September 14 with 90 mph winds and a 958 mb pressure — then crawled southwest along the NC/SC border at 2-3 mph for two days.

The rain broke both states' tropical-cyclone records: 35.93 inches at Elizabethtown, NC and 23.63 inches at Loris, SC. Surge up to 11 feet had already flooded New Bern via the Neuse River. Then the rivers — Cape Fear, Lumber, Little Pee Dee, Waccamaw — rose toward record crests for a week afterward. About 55 people died, most by freshwater drowning. Damage reached $24 billion.

The damage

At the coast, Florence was a survivable wind event: roof and siding damage, downed trees, near-total power loss around Wilmington. The catastrophe was water. New Bern's surge flooding required hundreds of rescues. Wilmington was cut off by floodwater for days. Whole counties of eastern North Carolina — Pender, Duplin, Jones — flooded as rivers left their banks.

South Carolina's disaster arrived on a delay. The Waccamaw at Conway crested at a record nearly two weeks after landfall. And Nichols, a Marion County farm town of about 400, flooded to the rooflines for the second time in 23 months: Hurricane Matthew (2016) had destroyed almost 90 percent of its 261 homes, and Florence inundated roughly 150 of the homes that had just been rebuilt. Homes, businesses, and the elementary school were abandoned after the second flood.

The insurance aftermath

Florence split cleanly along the wind/flood coverage line. Because landfall winds were Category 1, insured wind losses were moderate and carriers absorbed them without strain. The water was another story: estimates put uninsured flood losses near $20 billion — the bulk of the storm's total — because most of the flooded homes stood outside mapped high-risk zones and carried no flood policy. North Carolina had only about 134,000 NFIP policies in force statewide; roughly 445,000 covered NC, SC, and Virginia combined.

The NFIP ultimately performed for those who had it: more than 12,000 flood claims were filed within the first two weeks, and by September 2020 the program had paid $632.7 million to North Carolina policyholders. Homeowners carriers, meanwhile, generated the familiar denial patterns — flood exclusions applied to river water in living rooms, wind-driven-rain disputes where roofs leaked without visible breach, and depreciation and partial-roof-payment fights on wind claims.

Nichols made Florence a national exhibit for the NFIP's repetitive-loss problem: properties that flood, are rebuilt with claim payments and disaster aid in the same footprint, and flood again. Repetitive-loss properties are a small share of NFIP policies but a heavily outsized share of payouts, and Florence-after-Matthew put a face on the math. The policy responses that followed in the Carolinas — buyout and acquisition programs, elevation grants, South Carolina's disaster-recovery office relocation work in Nichols itself — all run on the same conclusion: the fourth flood claim costs more than the buyout.

What policyholders learned

• The flood map is not the flood. Most Florence flood victims were outside Special Flood Hazard Areas and uninsured. Lender-required coverage is a floor set by mapping, not a measure of actual risk — inland and riverine homeowners learned they needed flood policies no one required.
• Record crests arrive after the adjusters do. Rivers peaked up to two weeks post-landfall. Policyholders who re-documented damage at crest — not just at first inspection — captured the full loss.
• Wind-driven rain became the fight where wind was "only" Cat 1. Carriers attributed interior water to excluded flood or seepage; policyholders who documented storm-created openings preserved wind coverage for interior damage.
• Second-flood households faced 50%-rule and substantial-damage decisions. In Nichols, rebuilding twice in the same footprint triggered elevation and substantial-damage requirements. Owners who pursued buyouts or elevation grants exited the cycle; those who rebuilt in place re-entered it.
• Two disasters, two claim files. Matthew-then-Florence households had to keep the storms' damage separate — prior-damage arguments cut payouts where documentation of the Matthew repairs was thin. Completion photos of any post-storm rebuild are claim evidence for the next storm.
