How St. Landry Parish floods

Flash flooding driven by severe thunderstorms and stalled frontal systems dominates the flood history of St. Landry Parish, accounting for 36 of the 54 total flood events recorded over the last 30 years by the NOAA Storm Events Database. General floods, tropical storms, and hurricanes make up the remainder of the recorded event mix. Recent events illustrate this pattern, including heavy rainfall from a slow-moving storm system in January 2024, multiple rounds of severe thunderstorms producing flooding between May 12 and May 16, 2024, and moisture streaming north from decaying Tropical Storm Rafael in November 2024.

National Flood Insurance Program records show claims across multiple zones, with Zone A recording 522 claims averaging $27,700 with an average recorded water depth of 6 inches. Zone X accounts for 218 claims with an average payout of $37,513 and an average water depth of 5 inches, while unshaded Zone X records 148 claims averaging $28,546 with an average water depth of 8 inches. Zone UNKNOWN and Zone V recorded smaller numbers of claims with lower average water depths. Homeowners and real estate agents in Zone A and Zone X, where the vast majority of historical claims are concentrated, should pay the closest attention to these flood risks.

From the storm reports

Flash Flood · May 6, 2025. A warm front slowly lifted north across the region during the 6th causing rain and thunderstorms. A low pressure system and associated cold front slowly pushed back across the area on the 7th and stalled into the 9th with a couple rounds of heavy rain and thunderstorms.

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 13, 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 · May 13, 2024. Multiple upper disturbances moved across the region from the 12th through the 16th causing a rounds of strong to severe thunderstorms which produced numerous reports of damage, flooding, and high winds.

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.

  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 St. Landry Parish

If a building in St. Landry 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.
