How Morehouse Parish floods

Flash flooding from summer thunderstorms dominates the flood history of Morehouse Parish, supported by 46 recorded flash flood events over the last 30 years alongside river floods, tropical storms, and hurricanes.

Severe weather impacts are documented in recent historical records, including heavy rainfall and flash flooding from slow-moving thunderstorms in June 2025, and inland wind damage and flooding produced by the remnants of Hurricane Delta in October 2020.

Property owners in both high-risk and moderate-to-low risk zones have experienced flood losses. NFIP claims data shows significant impacts across designated areas, including 106 claims in Zone A with an average recorded water depth of 9 inches and an average payout of $30,403, as well as 67 claims in Zone X averaging an 11-inch water depth with an average payout of $48,680. Residents in Zone X_UNSHADED recorded 42 claims averaging 9 inches of water depth, Zone X_SHADED recorded 14 claims averaging 11 inches, and unknown zones recorded 10 claims averaging 1 inch of water depth. Homeowners and real estate agents in all mapped zones should account for these historical flood depths and claim frequencies when evaluating property risk.

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.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Morehouse Parish

If a building in Morehouse 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.
