Ellis County

Every recorded tornado

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

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).

   The most expensive damage was at Fort Hays State University, where the high winds blew off most of the roof from Weist Hall. Vehicles in an adjacent parking lot were damaged by roof debris. Extensive water damage occurred to the interior of the building. Some students and offices were relocated as a consequence of the damage. |The rainfall was so heavy that drains on Lewis Field were overwhelmed, and water accumulated under the special astro turf covering the field and lifted it from the field. |salvaged.

   National Weather Service narrative

   Tornado that began in eastern Trego county, steadily moved northeast before dissipating north of Hays. The tornado hit several farms in rural Ellis county and slammed into sparsely populated Yocemento. After leaving Yocemento, the tornado tore through a feedyard and on across other parts of rural Ellis county. Fortunately, the tornado stayed just west and north of populated Hays where a high school football game was in progress. The tornado damaged or destroyed 10 homes, a grain elevator, many outbuildings, a tractor and a feedlot. During the weaker moments of the tornado, it moved a 14,000 pound tractor 30 yards. One modular constructed home on a concrete slab was completely…
