Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
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.

Storm Prediction Center severe weather database, 1950 to 2025.

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.

National Hurricane Center HURDAT2, 1851 to 2025.

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.

The drought index is for Terrebonne Parish, the county that contains Houma.

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 city centre.
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 Rita produced extensive storm surge flooding across coastal areas of southern Terrebonne, southern Lafourche, and southern Jefferson Parishes where numerous homes and businesses were flooded. Some of the most substantial damage occurred in southern Terrebone Parish where storm surge of 5 to 7 feet above normal overtopped or breached local drainage levees inundating many small communities. Newspaper accounts indicated approximately 10,000 structures were flooded in Terrebonne Parish. Lafitte and other coummnities in lower Jefferson Parish also suffered extensive storm surge flooding. Storm surge flooding also occurred in some areas adjacent to Lakes Pontchartrain and…

4. Sep 11, 2008Storm Surge/Tide, Lower Terrebonne$100 million
   National Weather Service narrative

   Storm surge flooding of 5 to 8 ft above normal caused widespread flooding in lower Terrebonne Parish. Several local drainage levees were overtopped or breached and parish officials reported 2500 structures out of the 15000 stuctures in the area flooded. The high water took several weeks to drain from the region.

5. Aug 28, 2005Hurricane (Typhoon), Lower Terrebonne$42.5 million
   National Weather Service narrative

   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…

   National Weather Service narrative

   Zeta produced sustained hurricane force winds with gusts over 100 mph that led to widespread wind damage especially through Chauvin and Cocodrie near where the hurricane made landfall. The wind snapped or downed |hundreds of power poles along with trees an power lines. At the peak, almost two thirds of the parish was without power. A large carport was collapsed and torn from a house and there was also siding and roof damage to hundreds of homes. At least one home was flipped, though it appears the home was not anchored.

    National Weather Service narrative

    Ahead of Hurricane Zeta, officials issued mandatory evacuation orders for areas outside of the parish's levees and floodgates. The storm surge flooded several coastal roads, including LA HWY 56 with water rising under homes as well. The bottom levels of the Lumcon building were also flooded due to storm surge. A usgs gauge at Cocodrie (CCOL1) recorded a peak water level of 5.22 ft NAVD88. The Cutoff (CTFL1) tide gauge measured a peak of 4.62 NAVD88. The Dulac (DCLL1) tide gauge measured a peak of 3.33 NAVD88.
