How Avoyelles Parish floods

Flash flooding from slow-moving storms and tropical systems dominates the flood risk profile in Avoyelles Parish, supported by 22 flash flood events, five tropical storms, five general floods, and three hurricanes over the last 30 years. Recent events include a slow-moving storm system that brought multiple days of heavy rain in January 2024, and a stalled frontal boundary interacting with moisture from decaying Tropical Storm Rafael in November 2024.

National Flood Insurance Program records show claims spanning multiple zones, with the highest volume in Zone A at 1,087 claims averaging $9,768 and an average recorded water depth of 4 inches. Properties categorized as Zone X have also experienced significant financial impact, with 73 claims averaging $43,959 and an average water depth of 3 inches, alongside 170 claims in unshaded Zone X averaging $29,495 with an average water depth of 5 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within Zone A and unshaded Zone X areas, where claim volumes and average payout amounts indicate substantial flood exposure during heavy rainfall and tropical weather events.

From the storm reports

Flash Flood · Jan 24, 2024. A slow moving storm system affected Central and South Louisiana with multiple days of heavy rain and a few severe storms.

Flash Flood · Nov 9, 2024. A frontal boundary moved into the region and stalled while Tropical Storm Rafael meandered in the gulf. Moisture from the decaying tropical cyclone streamed north across Louisiana. This produced heavy rain over the area that produced flooding.

Flash Flood · Mar 22, 2022. A cold front and associated short wave moved into the region during the 22nd. Scattered storms developed as lift increased and storms eventually formed a line and moved east across south and central Louisiana. A few locations experienced flash flooding and one storm became severe.

Flash Flood · Sep 6, 2021. A cold front slow moved into the region sparking scattered thunderstorms. The very wet airmass in place allowed storms to produce high rain rates while slowly moving which produced flooding.

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.

Flood insurance in Avoyelles Parish

If a building in Avoyelles 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.
