Event by event

2 flood, 1 debris flow. Local standard time, as filed.

Flood, Henderson

When: December 1, 12:00 AM EST to December 3, 12:00 AM EST
Where: Henderson County, 1.09 mi NE of Fletcher to 1.8 mi SSW of Edneyville
Cause: Heavy Rain
Reported by: County Official
Coordinates: 35.440, -82.505

Although heavy rainfall began to diminish during the evening, persistent moderate rain combined with runoff to allow flooding to continue across Henderson County into the early morning hours of the 1st. Mud Creek and Bat Fork Creek remained in flood throughout the overnight hours as water worked its way down the French Broad River from Transylvania County. Flood waters on the river progressed as far north as Fletcher, which exceeded flood stage during the afternoon of the 1st. The French Broad River remained in flood until the morning hours of the 3rd.

Flood, Transylvania

When: December 1, 12:00 AM EST to December 3, 12:00 AM EST
Where: Transylvania County, 0.66 mi NE of Ecusta to 0.83 mi NNE of Blantyre
Cause: Heavy Rain
Reported by: County Official
Coordinates: 35.277, -82.712

Although the heavy rainfall began to abate during the mid-evening hours of November 30th, run-off from the previous heavy rain, combined with persistent moderate rain, caused flooding to continue. Floodwaters also progressed downstream along the French Broad River, and its tributaries, including the Little River and the Davidson River through the overnight hours. It was estimated that as many as 50 roads were closed or water-covered at the height of the flooding. Stream flooding ended early on the morning of December 1st, though river flooding lasted until the morning of the 3rd. Rainfall totals ranged up to 9 inches at Lake Toxaway, with many observers reporting 6 or more inches in and around Brevard.

Debris Flow, Henderson

When: December 1, 2:30 AM EST
Where: Henderson forecast zone
Property damage: $75,000
Reported by: County Official
Coordinates: 35.336, -82.480 (the zone’s center; the record gives no point)

After 6 to 10 inches of rain fell in around 24 hours, a landslide developed near the Holiday Dr area, pushing a small house off its foundation.

What these are

Flood: Flooding that develops more slowly than a flash flood: rivers leaving their banks, or water standing over land for an extended time.
Debris Flow: A fast-moving slurry of mud, rock and debris, usually on a slope soaked by heavy rain or stripped by a fire.

After NWS Directive 10-1605, the rules offices file Storm Data by.
