Isaias Remnants Bring High Winds and Flood Threats to Appalachia

The remnants of Hurricane Isaias are bringing strong winds, heavy rainfall, and potential flooding to parts of West Virginia, western North Carolina, and southwest Virginia over the weekend of October 10-11, 2026. The National Weather Service has issued wind advisories and flood watches as the weakened storm moves inland, threatening mountain communities with flash flooding, power outages, and possible landslides.

According to the National Hurricane Center, Isaias made landfall near Destin, Florida, on Friday, October 9, as a Category 2 hurricane, with sustained winds of 105 mph at approximately 9:30 p.m. ET. By 7:50 a.m. Saturday, October 10, the system had weakened into a tropical depression.

More than 560,000 electrical outages were reported across southern Alabama and the western Florida Panhandle following landfall. Georgia also experienced tens of thousands of outages by 7 a.m. Saturday, according to the report published by the Asheville Citizen-Times.

The National Weather Service issued a wind advisory for eight West Virginia counties, covering McDowell, Wyoming, Raleigh, Fayette, Nicholas, Webster, Pocahontas, and Randolph. The advisory runs from 5 p.m. Saturday until 11 a.m. Sunday, with the affected area extending from Welch to Elkins.

The agency forecast southeast winds of 20 to 30 mph, with gusts reaching 50 mph. Gusts could reach 60 mph along the highest ridgelines and in areas particularly exposed to downslope winds.

In western North Carolina, the National Weather Service office in Greenville-Spartanburg warned that the storm's center would pass well to the west, but moisture from the system could still produce hazardous conditions.

"Although the center of Isaias is forecast to pass well to our west, tropical moisture will impact our area, bringing heavy rainfall and potential flash flooding over the mountains, foothills, and northeast Georgia as well as very gusty winds, especially at high elevations," the National Weather Service Greenville-Spartanburg said in a Facebook post.

Wind advisories and high wind warnings remained in effect for western North Carolina communities through 8 a.m. Sunday, October 11. A flood watch covered the period from 8 a.m.

Saturday through 2 p.m. Sunday.

The National Weather Service office in Blacksburg also issued a flood watch covering Alleghany, Ashe, Surry, Watauga, and Wilkes counties in North Carolina, along with Carroll, Floyd, Grayson, and Patrick counties in southwest Virginia.

Forecasters expect widespread rainfall totals of 2 to 4 inches along the southern Blue Ridge, with localized amounts of 5 to 6 inches possible near Meadows of Dan, Boone, and Blowing Rock. The combination of heavy rainfall and mountainous terrain could cause streams to overflow, flood low-water crossings, and inundate roads and other low-lying areas.

The weather service also warned that saturated slopes and human-modified embankments could experience isolated landslides. Runoff may overwhelm storm drains and ditches, while rising creek and river levels could create additional flooding hazards.

In West Virginia, MetroNews meteorologist Bryan Hughes said isolated tornadoes could develop as the remnants pass through the region. He described the potential tornadoes as brief and small.

"We could have some of those spawn and they're going to be very, very small," Hughes said. "Usually these last 60 to 90 seconds, maybe up to 2 to 3 minutes and that's about it."

Hughes also forecast increasing rainfall as the storm approaches from the west and southwest, particularly after sunset Saturday. He expected some heavy storms by early Sunday morning.

"It's going to be as we get into the nighttime hours (Saturday), when the sun goes down that's when the rain starts to increase from the west and southwest," Hughes said. "By Sunday morning earlier we're going to have storms, some of them heavy."

Hughes said the storm was expected to be a tropical depression on Sunday, with its center approaching as close as Grayson, Kentucky. He added that recent dry conditions across West Virginia could help the ground absorb incoming rainfall, although localized flash flooding remained possible.

"By being dry for the past two to three weeks, that's allowed us to be able to take some of the water that's coming at us, but still, we could have some flash flooding in some areas," Hughes said.

Forecasts for the Upstate South Carolina area also called for persistent rain and strong winds on Saturday. Expected rainfall ranged from one-half to three-quarters of an inch during the day, with another 1 to 2 inches possible overnight. Showers were forecast to taper on Sunday, followed by mostly sunny conditions on Monday, October 12.

In West Virginia, the forecast indicated that West Virginia University's noon football game against Arizona in Morgantown would likely remain dry Saturday. Marshall's 7 p.m. game against Coastal Carolina in Huntington faced a greater chance of rain.
