How Claiborne Parish floods

Flash flooding from severe weather events dominates the flood risk profile in Claiborne Parish, accounting for the vast majority of recorded storm events over the last 30 years alongside occasional tropical systems and general floods. Historical events documented by NOAA include a Mesoscale Convective Vortex that produced heavy repeated rainfall and flash flooding in July 2023, as well as significant impacts from Tropical Storm Laura in August 2020 and a stationary upper-level low system in March 2016.

National Flood Insurance Program records indicate that high-risk Zone A properties have experienced the most significant impacts, logging 42 claims with an average payout of $45,920 and an average recorded water depth of 17 inches. Moderate- and low-risk zones also carry residual risk; unshaded Zone X properties recorded 11 claims with an average payout of $44,368 and an average water depth of 7 inches, while shaded and standard Zone X properties averaged 2 inches of water across 12 total claims. Homeowners and real estate agents in Zone A and unshaded Zone X areas should pay the closest attention to historical claim payouts and recorded water depths when evaluating property risk.

Where the flood claims came from

29% of Claiborne Parish’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

59 NFIP claims with a recorded rated flood zone, 1978 to date. The zone is the one FEMA used to rate that policy, which may not match today’s map. Source: OpenFEMA NFIP claims.

From the storm reports

Flash Flood · Jul 12, 2023. A Mesoscale Convective Vortex (MCV) that was a remnant of showers and thunderstorms over Central Oklahoma on July 11th, drifted east into Southwest Arkansas during the early morning hours of the 12th. This upper level disturbance moved over an area that was very warm, moist, and unstable, and focused a cluster of showers and thunderstorms throughout much of the morning hours before drifting east out of the region…

Tropical Storm · Aug 27, 2020. Major Hurricane Laura tracked north northwest across the Central and Northern Gulf of Mexico from the Central Carribean Sea near Cuba, making landfall in Southwest Louisiana near Cameron around 1 am on August 27th as a strong Category 4 hurricane with maximum sustained winds near 150 mph, and a minimum central pressure of 938 mb. Laura remained a hurricane as it tracked north across Southwest and Central Louisiana…

Flash Flood · Mar 9, 2016. A strong upper level low pressure system settled over northern Mexico on March 8th, and became stationary through March 12th as it was cut off from the upper level jet stream, with a blocking upper ridge having developed over Florida and the western Atlantic. Meanwhile, a weak frontal boundary entered the region from the west on the 8th, and became stationary over Deep East Texas, Northwest Louisiana, and Southwes…

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. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  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.

Flood insurance in Claiborne Parish

If a building in Claiborne 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.
