Calhoun County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Calhoun County: 4.
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.

   National Weather Service narrative

   Hurricane Michael started as typical weak October Caribbean tropical system. However, after approximately a week of slow development, the system moved into warm Gulf of Mexico waters and rapidly intensified into a major hurricane as it moved north towards the Florida Panhandle. After a 2-day long intensification period over the eastern Gulf, Michael made landfall as an unprecedented (for the region) high-end category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale in the Florida Panhandle with maximum sustained wind speed of 155 mph and a minimum pressure 919 mb. Based on wind, Michael is the fourth most powerful hurricane to hit the United States, behind the Labor Day…

   National Weather Service narrative

   Hurricane Georges, a Category 2 storm, made landfall near Biloxi, MS early Monday, September 28, 1998. A peak wind gust of 52 knots was measured at the Gulf of Mexico data buoy 85 nautical miles south of Panama City. Georges produced storm surges of 6 to 12 feet along the Florida Panhandle coast and 3 to 5 feet along the Big Bend coast. Torrential rainfall amounts of 12 to 24 inches were common over Southeast Alabama and the Florida Panhandle with 5 to 10 inches over Southwest Georgia and the Big Bend. These rains swelled area rivers, creeks, and streams well above flood stage. Eight people were injured as numerous tornadoes were spawned by the remnants of Tropical Depression…

6. Sep 15, 2004Tornado$2.5 million
   National Weather Service narrative

   The supercell thunderstorm which spawned tornadoes in Franklin and Liberty counties, produced a strong F2 tornado, which touched down just southeast of Van Lierop Road, a few miles east of Highway 69. It crossed Highway 69 near the Stafford Creek Bridge, and peeled roofs from dozens of homes, uprooted trees, and scattered debris. The tornado then struck the Macedonia Community at Highway 69-A and Parrish Lake Road. It demolished three trailers and damaged 30 homes. The tornado picked up two neighboring mobile homes. One was thrown across a road and killed its two occupants. Another was slammed into a neighbor's house, which killed its two occupants and injured five others.…

9. Nov 17, 2014Tornado$2.0 million
   National Weather Service narrative

   The tornado likely began in a heavily forested area with limited access just SW of the Calhoun Correctional Institution - between the prison grounds and Highway 71. The beginning point was estimated based on the rest of the damage path and a lack of observed damage along Highway 71. The tornado then quickly intensified as it moved into the prison grounds. Several concrete buildings were heavily damaged - including a two-story printing facility. The eastern wall of that particular building was completely collapsed with the roof almost entirely removed. An adjacent concrete building also had large sections of roof removed. The damage to both of these buildings was rated EF2 with…
