Overview of Hurricane Florence in Raleigh
Hurricane Florence made landfall in North Carolina in September 2018 as a Category1 hurricane and stalled over the region, producing record rainfall across the Triangle. In Raleigh, this led to widespread flooding, road closures, and sustained power outages. The event reshaped local drainage policies, building codes, and emergency communications. This evergreen explainer details the meteorology, impacts, and verified recovery milestones to help residents and planners understand risks and long‑term resilience measures.
Meteorology and Forecast Timeline
Florence originated from a tropical wave off Africa in mid‑August 2018, intensified in the Atlantic, and was accurately forecast to approach the Southeast United States about a week before landfall. Models consistently indicated a high‑likelihood landfall in the Carolinas, allowing Raleigh officials to activate emergency plans early. The storm’s unusual westward track and slow motion increased the duration of heavy rain over inland areas, amplifying flood risk in urban watersheds.
Key Forecast and Track Details

Rainfall and Flooding in Raleigh
Raleigh recorded some of its largest multi‑day rainfall totals on record, with many gauges exceeding 15inches across the county. Streams and retention basins overflowed, overwhelming stormwater systems and causing significant street and river flooding. Neighborhoods along lower‑lying corridors faced extended inundation, highlighting the vulnerability of aging drainage infrastructure. The rainfall also triggered slow‑moving landslides in the nearby hills, complicating access and recovery.
Verified Rainfall and Flood Observations
- Peak 24‑hour rainfall: over 10inches at several NCAC gauge sites
- Creek and river stages: Neuse River and tributaries reached major flood stage
- City service requests: Tens of thousands of calls for drainage and rescue
Infrastructure and Service Impacts
Power outages affected hundreds of thousands of customers in the Raleigh area, with some outages lasting over a week in localized areas. Floodwaters damaged roadways, culverts, and bridges, prompting long‑term repairs to key arterial routes. Wastewater and water treatment plants implemented contingency plans to maintain service, though pressure loss and boil‑water advisories occurred in spots. The event accelerated upgrades to drainage standards and the adoption of green infrastructure in city projects.
