Mooresville

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
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 in Iredell County, the county that contains Mooresville.

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.

The drought index is for Iredell County, the county that contains Mooresville.

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.

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 city centre.
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).

   National Weather Service narrative

   Multiple sources reported severe urban and small stream flooding developed in the city of Statesville when training showers produced as much as 7 inches of rainfall across the city in just a few hours. Several swift water rescues became necessary as vehicles became submerged and water entered structures. Multiple roads were flooded and closed, including Shelton Ave at Allison St, Springdale Dr at Georgia Ave, and Sullivan Rd. The flooding on Sullivan Rd was due to Free Nancy Branch overflowing its banks.

   NWS storm survey found the path of a second, more significant tornado in Iredell County. This one touched near the intersection of New Salem Rd and Highway 64. The tornado moved northeast, crossing Highway 64 between Crooked Ln and Hunters Ridge Ln. The most significant damage occurred in this location, as a brick home had its roof completely removed and interior walls collapsed. Material from this home along with tree debris acted as projectiles, causing damage to the exterior of adjacent homes. About a dozen homes were damaged in this fashion. The tornado apparently weakened as it continued northeast, but uprooted or snapped dozens of trees before lifting in the vicinity of 5th…
