Isaias Remnants Flood Western North Carolina: Rescues in Burke County, 840,000 Gallons of Sewage in Hunting Creek

The short version: The remnants of Hurricane Isaias spent the weekend drenching western North Carolina — spawning confirmed tornadoes, pushing creeks out of their banks, forcing swift-water rescues, and overwhelming Morganton's sewer system so badly that about 840,000 gallons of sewage overflowed into Hunting Creek on Sunday. By Monday, Governor Josh Stein could announce the sentence everyone in the foothills was holding their breath for: no one was reported hurt.

The spill in Morganton

The City of Morganton said intense rainfall overwhelmed a sewage junction box on Vine Arden Road, near the city's wastewater treatment plant, causing a spill that lasted about two hours on Sunday. Roughly 840,000 gallons of sewage — rainwater that had infiltrated the system mixed with untreated wastewater — overflowed into Hunting Creek, according to the city's release, which state law requires for any spill of 1,000 gallons or more that reaches surface water.

It was not the only failure of the night. Earlier Sunday, flooding at a manhole sent about 1,500 gallons of sewage into a storm drain over roughly five hours, from about 1 a.m. to 6 a.m. Together, the two spills are the latest entries in a familiar Burke County pattern: when the foothills get several inches of rain at once, water finds its way into sewer lines never built for it, and the system relieves itself into the nearest creek. The state Division of Water Resources reviews each reported discharge.

Rescues across Burke and McDowell

The human emergencies came first. Swift-water rescue teams in Morganton saved campers who had been caught by rising water and were holding onto a dock in waist-high swift water behind Freedom High School. In Burke County, an unhoused man and woman camping near the Catawba River were rescued when floodwaters rose around them — their dog was saved, too — and another woman was freed from a car trapped in floodwater outside Morganton. Several roads and low-lying areas flooded, including a mobile home park along Antioch Road.

Next door in McDowell County, first responders handled five landslides and carried out voluntary evacuations overnight Saturday into Sunday. By Monday morning, the county's emergency operations center was closing back down, with officials thanking the 911 telecommunicators, field crews, public works staff and shelter workers who had run the night — and warning drivers to keep treating damaged roads and flooded crossings with respect while streams settle.

A region that has seen worse — and knows it

None of this happened in a place that needed a reminder. Western North Carolina is two years removed from Hurricane Helene, which devastated the region in 2024, and Burke County officials spent last week saying, in almost so many words, that this was not Helene — while standing up the emergency operations center anyway and pre-positioning swift-water teams that, as it turned out, were needed within hours.

The National Weather Service confirmed multiple tornadoes across the Carolinas on Saturday and Sunday, including an EF0 with 75 mph winds at East Arcadia. Isaias itself had struck the Gulf Coast on Friday, October 9, before weakening into a post-tropical system and dragging its rain northeast. In the foothills, the storm's last act was water: in creeks, on roads, in a sewer system that could not hold it. The cleanup — and the state's review of an 840,000-gallon spill — starts now.

The preparation that was already in place

One reason the weekend produced rescues instead of funerals is that Burke County never really stood down after Helene. Ahead of Isaias, county spokesman Chris White told residents plainly that this storm was not Helene — while the county simultaneously stood up its emergency operations center in standby mode, engaged emergency services, and watched the eastern slopes of the Blue Ridge, where forecasters expected the heaviest rain and the highest landslide risk once soils saturated. The trigger officials watch for is more than five inches of rain in 24 hours; White said the county would come close.

In a coincidence that turned into an asset, Burke County was also hosting a long-planned swift-water response training that weekend, bringing multiple rescue teams from across the state into the area just as the real calls started coming in. The State Emergency Response Team was deploying resources across North Carolina at the same time. When campers ended up clinging to a dock behind Freedom High School in waist-high moving water, the people trained to get them out were already in the county.

That posture — assume the forecast is the floor, not the ceiling — is the clearest lesson western North Carolina carried out of 2024, when Helene devastated the region and left communities like Avery County still searching for their last missing victim two years later. Isaias was a smaller storm by every measure. In Burke and McDowell counties this weekend, smaller was enough to flood a mobile home park, slide five hillsides, force rescues across two counties, and send 840,000 gallons of sewage into Hunting Creek. The region's new normal is that there is no such thing as just rain anymore.
