Remnants of Hurricane Isaias Trigger Flooding, Power Outages Across Western North Carolina
By Drooid · · How we work
Event Overview
The post-tropical remnants of Hurricane Isaias moved westward into the Appalachian foothills, bringing heavy rain, gusty winds and widespread power disruptions. Meteorologists reported several locations received 7–8 inches of rain after midnight. The National Weather Service (NWS) issued Flood Watches for a dozen western counties, while local emergency managers activated swift-water rescue teams, flood-warning sirens and road-closure orders. Downed trees and power poles knocked out electricity for an indeterminate number of customers, prompting utility crews to begin restoration efforts under hazardous conditions.
Background & Context
Isaias made landfall on the Florida Panhandle as a Category 2 hurricane, producing sustained winds of 105 mph and storm-surge flooding that left over 700,000 customers without power. After losing tropical characteristics, the system retained a strong rain core that tracked northeastward into the Carolinas. At the same time, central North Carolina remains in a moderate to severe drought, with key reservoirs such as Falls Lake at 74 percent capacity and Kerr Lake just above 50 percent.
Timeline

| Early Sunday | Rain totals of 7–8 inches recorded in multiple spots; flash-flood warnings activated; landslides reported on NC-226A and other mountain roads. |
| Throughout Sunday | Emergency managers deploy swift-water rescue teams, open flood-warning sirens, and advise residents to avoid low-lying roads. |
| Ongoing | Flood Watches remain in effect; high-wind warning continues for elevations above 3,500 ft with gusts up to 60 mph. |
Data & Statistics
- Rainfall: 7–8 inches in several locales after midnight; 2–4 inches across most western counties in the preceding 12 hours; additional 1–2 inches forecast through early Sunday.
- Wind: High-wind warning predicts gusts up to 60 mph above 3,500 ft; local reports note gusts near 30 mph limiting bucket-truck operations.
- Flooding: Flash-flood warnings issued for McDowell, Henderson, and other counties; isolated road closures on Sugar Hill Rd, Lytle Mountain Rd, US 74A, and NC-226A.
- Landslides: Confirmed slide on NC-226A near the McDowell county line; additional slide risk noted where 5 inches of rain fall within 24 hours.
Emergency Response
- Utility actions: Duke Energy deployed crews from coastal staging areas to Asheville and surrounding counties, advising the public to stay away from downed lines and suspending bucket-truck work when winds exceed 30 mph.
- Fire and rescue: North Canton Fire warned motorists of a two-car crash on I-40 due to slick conditions; Asheville’s REST team advised relocation from flood-prone encampments.
- Swift-water teams: Mooresville Fire-Rescue dispatched twelve members to Yancey County.
- Shelters: Emergency shelters were opened ahead of the storm, and officials urged residents to heed sirens, road barricades and evacuation orders.
Conflicting Reports & Gaps
No source provided precise numbers of customers without power or exact flood-stage measurements for all affected streams, leaving a gap in quantifying the full scale of outages and inundation.
What’s Next
The NWS maintains Flood Watches for the listed western counties through Sunday afternoon, and a high-wind warning remains in effect for elevations above 3,500 ft until early morning. Residents are advised to monitor local alerts, avoid flooded roadways and prepare for possible additional rain showers overnight.
