How Red River Parish floods

Flash flooding from severe weather events and heavy rainfall dominates the flood history of Red River Parish, supported by 29 flash flood events alongside standard floods, tropical storms, and hurricanes recorded over the last three0 years. Severe rainfall is frequently driven by stalled surface fronts, upper-level troughs, and moist southwesterly flow from the Gulf of Mexico. Recent events include a heavy rainfall and frontal boundary system in January 2024, a linear mesoscale convective system in June 2024, and moisture-fed thunderstorms in April 2024, as well as a vigorous upper-level trough and low-level jet system in January 2023.

National Flood Insurance Program claims data indicates that properties located in high-risk zones face the most severe impacts. Zone A properties experienced 11 claims with an average payout of $37,819 and an average recorded water depth of 8 inches. By comparison, unshaded Zone X properties recorded 5 claims with an average payout of $1,202 and an average recorded water depth of 3 inches. Homeowners, real estate agents, and journalists working with properties situated in Zone A should pay the closest attention to flood risk and mitigation measures given the substantially higher historical payouts and water depths in these areas.

In flood insurance claims here that reported a flood depth, the average was 7 inches.

From the storm reports

Flood · Jan 23, 2024. A deep upper-level trough axis became entrenched across the western U.S. early on January 23rd, enhancing a deep southwesterly flow pattern across the Middle Red River Valley. Multiple disturbances aloft ejected northeast within the southwesterly flow and combined with a stalled surface frontal boundary to provide a nearly ideal environment for heavy rainfall across the Ark-La-Tex region. The axis of heaviest rain…

Flash Flood · Apr 9, 2024. A frontal boundary became stationary across the heart of the Ark-La-Tex region in vicinity of the Interstate 30 corridor on April 8th before slowly advancing southeast on April 9th. Concurrently, very moist southwest flow aloft resulting from a nearly cut-off low across the Desert Southwest provided for precipitable water values near 2 inches. Thunderstorms developed and gradually spread northward from Central…

Flash Flood · Jun 3, 2024. A linear mesoscale convective system (MCS) advanced southeast into the Ark-La-Tex from Oklahoma during the afternoon and evening hours on June 3rd. A pocket of strong instability was present ahead of the line, where MLCAPE values ranged from around 2500 to 3500 J/kg range and surface dew points were in the 70s. Instability along with strong large-scale ascent associated with a vorticity maxima and low-level conver…

Flash Flood · May 11, 2023. An upper level low pressure system slowly ejected northeast across the piney woods of East Texas during the evening through the morning hours of May 10th-11th. A southerly low level jet present ahead of the low spilled copious amounts of low level moisture north into East Texas and Western Louisiana, with strong large scale forcing ahead of the low enhancing numerous shower and thunderstorm development which moved…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley.

  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.

Flood insurance in Red River Parish

If a building in Red River Parish is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
