Hammond

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.

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 in Tangipahoa Parish, the county that contains Hammond.

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.

The drought index is for Tangipahoa Parish, the county that contains Hammond.

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).

1. Aug 12, 2016Flash Flood$629 million
   National Weather Service narrative

   Twelve to eighteen inches of rainfall over a 2 day period led to widespread flash flooding across roughly the northwestern half of Tangipahoa Parish. As water drained into the local rivers, record levels were recorded on the Tangipahoa and Natalbany Rivers. Additional details of the river flooding can be found in the flood report for the parish. As floodwaters rose, hundreds of high water rescues were necessary across the parish. On Friday the 12th, I-55 was closed due to high water near exit 40 in Independence and from exit 50 to exit 53 between Fluker and Arcoloa. More than 11,000 homes and businesses suffered various degrees of flooding, though it's difficult to determine how…

   Twelve to eighteen inches of rainfall over a 2 day period led to widespread flash flooding across the northwestern half of Tangipahoa Parish, details of which are contained in the flash flood report for the parish. As water drained into the local rivers, major to record flooding occurred along the Tangipahoa River. Flooding far exceeded the 1% annual risk flood plain. Interstate 55 was closed from exit 50 to exit 53 between Fluker and Arcola due to water over the roadway. Additionally, the entirety of Interstate 12 through Tangipahoa Parish was closed as flood crests on both the Tangipahoa and Natalbany Rivers pushed high water onto the roadway. The end time of the event is based…

3. Aug 29, 2021Hurricane (Typhoon), Southern Tangipahoa$300 million
   National Weather Service narrative

   Ida���s winds downed trees and power lines parish-wide as the eastern eyewall traversed far western portions of the parish. Many structures throughout the parish suffered at least minor to moderate roof or other fascia damage, and numerous buildings suffered other major damage from roof failure or falling trees. Most roads in the parish were impassable due to downed trees, power lines and poles, or other debris. There were two indirect fatalities in the parish: one nursing home death and one due to carbon monoxide poisoning.

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…

The hurricane weakened rapidly to a Saffir Simpson Scale Category 1 Hurricane by the time it made landfall during the morning of October 3rd along the south central Louisiana coast. The hurricane continued to moved north northwest across south central Louisiana before turning northeast across the northern portion of the state. Due to the rapid weakening, no sustained hurricane force winds were measured in southeast Louisiana. However, storm surge was significant across the southeast…
