Somervell County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Somervell 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.

Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

Monitoring Trends in Burn Severity (USGS and U.S. Forest Service), 1984 to 2026.

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.

NOAA NCEI nClimDiv county Palmer Drought Severity Index, 1895 to September 2026, issued October 6, 2026.

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).

   National Weather Service narrative

   Persistent drought conditions continued across portions of north Texas. According to the U.S. Drought Monitor, much of the region was still experiencing extreme (D3) drought conditions. The areas which were rated exceptional drought (D4) last month had received enough rainfall to be downgraded into the D3 category this month.|Even though drought conditions were lessened by a few rain events this month, serious hydrological problems remained. For instance, as much water was used from Lake Bridgeport in one month alone as was saved through conservation efforts by north Texas over the summer. Almost every north Texas lake remained well below conservation levels. The rain events this…

8. Feb 1, 2011Ice Storm, Somervell$40,000
   National Weather Service narrative

   Heavy sleet blanketed the county followed by 1-1.5 accumulation of snow. The sleet and ice made travel treacherous around the county. Most of the vehicle incidents reported were due to stuck vehicles or vehicles that had slid off the roadway. The prolonged cold that settled in after the ice storm kept the roads treacherous for the next four days and many schools and businesses were closed for just as long. Three vehicle accidents around Glen Rose during the week involved minor injuries.

    Up to 2 of snow fell across the county but at night, the snow froze on the roadways, creating icy roads and treacherous travel conditions across the county through Christmas morning. Some of the accidents from the icy roads resulted in minor injuries.

1. Storm Events records before 1996 cover only tornadoes, thunderstorm wind and hail. Damage figures are as reported by the National Weather Service at the time, not adjusted for inflation.
