New Hanover County · NC
Wilmington's direct Atlantic coastal position gives it meaningfully more severe, direct hurricane exposure than the inland North Carolina cities (Charlotte, Raleigh, Asheville) this site already covers — Hurricane Florence made landfall very close to Wilmington in 2018 and caused catastrophic, extensively documented flooding across the region. This real, recent history is a major reason standby power planning in Wilmington tends to center on extended, multi-day outage scenarios rather than shorter, more routine severe-thunderstorm outages.
