How Covington County floods

Flash flooding from severe weather and tropical systems dominates the flood risk in Covington County. Over the last 30 years, the NOAA Storm Events Database recorded 19 flash floods, 3 tropical storms, 2 hurricanes, and 1 general flood. Recent events include strong storms on May 17, 2024, that produced damaging wind gusts and flash flooding, as well as Hurricane Sally in September 2020, a slow-moving Category 2 storm that moved inland and produced widespread freshwater flooding across south-central Alabama.

Federal flood insurance claims data shows impacts across different zones. Properties in Zone A experienced the highest frequency with 30 claims, averaging an $11,317 payout and an average recorded water depth of 13 inches. Properties in Zone X accounted for 4 claims with an average payout of $29,111 and an average recorded water depth of 1 inch. Zone X unshaded properties recorded 3 claims with an average payout of $43,868 and an average recorded water depth of 1 inch.

Homeowners and real estate agents in Zone A should pay the closest attention to flood risks given the higher frequency of claims and greater average water depths, while properties in Zone X and unshaded Zone X areas must also account for potential severe water damage during major inland tropical systems and heavy rainfall events.

From the storm reports

Flash Flood · May 17, 2024. Strong to severe storms moved across Alabama into the Florida Panhandle producing damaging wind gusts and flash flooding.

Flash Flood · Jun 15, 2023. Unusually strong wind shear combined with strong instability and numerous disturbances led to a very active period of severe weather through the month of June. Numerous reports of large hail and damaging winds were recorded along with a few tornadoes.

Flash Flood · Sep 16, 2020. Hurricane Sally made landfall in Gulf Shores, AL at 5am on Wednesday, September 16th as a strong Category 2 hurricane with maximum sustained winds of 105 mph. Sally produced widespread wind, storm surge, and freshwater flooding across coastal AL and the western Florida Panhandle. Flood and wind damage also extended well inland into inland southwest Alabama and south central Alabama. Sally was an extremely slow mov…

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 Covington County

If a building in Covington County 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.
