Humphreys County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Humphreys County: 38.
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).

   National Weather Service narrative

   This long track, violent tornado began over northern Issaquena County near Grant Rd, downing multiple trees and damaging two older outbuildings. It tracked northeastward, producing tree damage as it crossed the Steele Bayou Canal before crossing into Sharkey County. At this point, the tornado began to substantially increase in size and intensity. A very high percentage of trees were snapped along the path through a wooded area south of Bear Lake Rd. It was in this wooded area where the first indications of EF3 to EF4 damage were noted, with at least one tree and root ball and several more large tree pieces fully displaced into the downstream field. From this point along the path…

Several homes were significantly damaged, a modular commercial building was totally destroyed, the Belzoni school bus barn was heavily damage, and a number of cars, school buses and farm vehicles had windows blown out. After the tornado moved through the…

6. Aug 29, 2005Hurricane (Typhoon), Humphreys$500,000
   National Weather Service narrative

   Hurricane Katrina will likely go down as the worst and costliest natural disaster in United States history. The amount of destruction, the cost of damaged property/agriculture and the large loss of life across the affected region has been overwhelming. Catastrophic damage was widespread across a large portion of the Gulf Coast region. The devastation was not only confined to the coastal region, widespread and significant damage occurred well inland up to the Hattiesburg area and northward past Interstate 20. This hurricane has changed life as we know it across the Gulf Coast region which will take many years to return to normal.Hurricane Katrina was a very large and powerful storm…

8. Dec 23, 1998Ice Storm, Humphreys$350,000
   National Weather Service narrative

   A crippling ice storm struck the three state region of Arkansas, Louisiana, and Mississippi at one of the worst times, just before Christmas. Much of the fall and early winter season of late 1998 had been very mild for southerners. But on Tuesday December 22nd, a strong surge of shallow Arctic air drove southward and spelled a quick end to the unseasonable warmth and helped set the stage for one of winter's nasty tricks. A moist southwest flow above the cold air brought several upper level disturbances. This combination of cold air and moisture held together for several days and brought periods of freezing rain and sleet to the three state region, beginning tuesday night and not…
