Washington Parish

Every recorded tornado

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

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.

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).

   Hurricane Katrina was one of the strongest and most destructive hurricanes on record to impact the coast of the United States. It will likely be recorded as one the worst natural disaster in the history of the United States to date resulting in catastrophic damage and numerous casualties in southeast Louisiana and along the Mississippi coast. Damage and casualties resulting from Hurricane Katrina extended as far east as Alabama and the panhandle of Florida. Katrina developed from a tropical depression southeast of the Bahamas on August 24th. After moving through the Bahamas as a tropical storm, Katrina strengthened to a category 1 hurricane prior to landfall in south Florida…

   Isaac entered the Gulf of Mexico as a tropical storm on August 26, moving northwest after crossing Haiti, Cuba and the Florida Straits. Isaac strengthened into a hurricane on the morning of the 28th when it was 75 miles south-southeast of the mouth of the Mississippi River. Isaac made landfall in Plaquemines Parish as a Category 1 Hurricane near Southwest Pass of the Mississippi River on the evening of the 28th. A second landfall occurred near Port Fourchon the following morning. The storm weakened to a tropical storm on the afternoon of the 29th about 50 miles west southwest of New Orleans, and weakened further to a tropical depression on the afternoon of the 30th near Monroe,…

7. Mar 10, 2016Flash Flood$1.6 million
   National Weather Service narrative

   Rainfall of 8 to 15 inches fell across much of the parish during the evening and overnight hours. A rainfall observer near Mt. Hermon, in the far northwest section, recorded 16 inches of rainfall. The runoff from the heavy rainfall produced life threatening flash flooding in many areas of the parish. An estimated 1100 homes were flooded along with 30 churches. Approximately 80 roads were damaged or made impassable, mainly from washed out culverts and bridges. Areas that were especially hard hit was near the Fairgrounds in Franklinton, areas of Bogalusa and areas around Mt. Hermon. Numerous search and rescue operations were conducted in the overnight hours rescue residents and…

   Hurricane Cindy developed from a tropical depression that formed over the extreme western Caribbean Sea on July 3. This depression moved northwest over the Yucatan Peninsula and emerged over the south central Gulf of Mexico on July 4. On July 5th the depression strengthened into a tropical storm and moved north toward the southeast Louisiana coast. Cindy made landfall in southeast Louisiana early on July 6th just to the west of Grand Isle, and reached minimal hurricane strength for a short period of time. Cindy then turned toward the northeast and moved over the New Orleans area and toward the Mississippi coast before dissipating inland over central Alabama later that day. Cindy…

    Runoff from the heavy rainfall caused the Bogue Chitto River to reach its highest levels since the April 1983 flood event, and surpass the 1983 flood event in the lower portion of the river. A historic crest of 21.36 feet was reached on the Bush, LA river gage on March 12.
