How Holmes County floods

Holmes County experiences a flood risk profile dominated by standard floods and flash floods, supplemented by tropical storms and hurricanes. Over the last 30 years, NOAA recorded 63 flood events, 49 flash flood events, 15 tropical storm events, and 4 hurricane events. Recent severe weather includes a major flash flood event from April 10–11, 2024, and multiple flash flood events associated with Category 4 Hurricane Helene on September 25–26, 2024, which featured 140 mph maximum sustained winds and a storm surge exceeding 15 feet along the Apalachee Bay coast.

National Flood Insurance Program records reflect claims across different zones with varying impacts. Properties in Zone A account for 130 claims with an average payout of $18,247 and an average recorded water depth of 17 inches. Zone X properties account for 23 claims with an average payout of $30,991 and an average recorded water depth of 24 inches. Properties with an unknown zone account for 12 claims with an average payout of $8,804 and an average recorded water depth of 8 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within Zone A, which received the highest volume of insurance claims, as well as properties in Zone X, which experienced higher average payout costs and greater recorded water depths during flood events.

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 Holmes County

If a building in Holmes 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.
