Alexander County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Alexander County: 0.
2. Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

Every storm within 100 miles

1. Tropical storms and hurricanes (34 kt or more, still tropical) at closest approach. Post-tropical remnants with gale-force winds are listed but not counted. Direct: track within 50 miles; near: within 100 miles. Distance is measured to the county boundary for counties and to the city centre for cities, using positions interpolated hourly between HURDAT2 fixes.

Smoke overhead

1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

River crests

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

Every earthquake of magnitude 4 or more within 50 miles

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

Mapped landslides

Mapped by NC GS (1).

1. Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

1. Dec 4, 2002Ice Storm, Alexander$8.0 million

A transition to sleet and then freezing rain occurred during the late evening, and ice accumulated to between 1/4 and 1/2 inch. The result was widespread power outages, which lasted for a week or more in some areas.

2. Apr 4, 2011Thunderstorm Wind$1.0 million
   National Weather Service narrative

3. Mar 20, 2001High Wind, Alexander$1.0 million
   National Weather Service narrative

   Many thousands of trees were downed in the mountains, where the character of the wind was a steady, persistent wind of 35 to 45 mph with higher gusts for the duration of the event. In the foothills and piedmont, where lower threshold winds were observed, damage was not as widespread but there were still scattered downed trees and power lines.

4. Aug 18, 2011Tornado$500,000
   National Weather Service narrative

   A small area of tornadic damage was surveyed in the Powell Rd, Taylorsville Manufacturing Rd area. A manufactured home was pushed off its block foundation and several outbuildings were destroyed. Several homes also received damage due to wind-blown hail.

5. Sep 27, 2024Tropical Storm, Alexander$500,000
   National Weather Service narrative

   Thousands of trees were blown down, with dozens of trees down on homes, vehicles, and power lines. Frequent gusts up to 60 mph occurred, with occasional gusts of 70 mph.

6. Apr 16, 2007High Wind, Alexander$500,000
   National Weather Service narrative

   After an intense, but relatively brief high wind event affected the mountains and foothills on the evening of the 15th, another widespread damaging high wind event developed during the day of the 16th. However, this particular event included much of the piedmont. Thousands of trees fell across the area, resulting in widespread power outages. Numerous trees fell on roads, homes, and vehicles. The Blue Ridge mountains and the foothills received the brunt of the strongest winds. In Highlands, NC, two homes were heavily damaged by fallen trees, while approximately 100 homes received minor to moderate damage. A tree fell on and severely damaged a home in Otto, NC.

    National Weather Service narrative

    Emergency manager reported major flash flooding developed throughout Alexander County after up to 9 inches of rain fell in 24 hours, with around half of that falling in a 3-hour period prior to daybreak on the 12th. The most significant flooding occurred along the South Yadkin River in the Hiddenite area. Multiple recreational vehicles and campers were swept down the river from a campground off Princess Ln. Five people, ages ranging from 1 to 76, drowned and 31 more people required rescue from rapidly rising flood water.
