How Ripley County floods

River flooding and flash flooding from storms dominate Ripley County, with the NOAA Storm Events Database recording 45 floods and 39 flash floods over the last 30 years. Recent events illustrate this pattern, including torrential rainfall rates that produced flooding in Naylor on July 27, 2025, and a severe weather outbreak that caused flooding on May 26, 2024. Additional heavy rainfall along a slow-moving frontal boundary affected the region from November 4 through November 6, 2024, impacting water levels on the Current and St. Francis rivers.

Federal flood insurance claims data shows the greatest impact occurs in designated high-risk areas. Zone A accounts for 204 claims with an average payout of $57,039 and an average recorded water depth of 10 inches. Properties in Zone X recorded an average payout of $125,952 and an average water depth of 6 inches across 7 claims, while Zone X Unshaded recorded an average payout of $99,286 with an average depth of 7 inches across 8 claims. Zone Unknown recorded 25 claims with an average payout of $11,087 and an average depth of 5 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within Zone A and near river systems, as well as areas where historical claims indicate recurring water accumulation.

From the storm reports

Flood · Jul 27, 2025. On the 27th, the Quad State was in the middle of an extended heat wave, with high dew points contributing to a very moist environment. As a band of afternoon thunderstorms took shape in southern portions of the Ozarks, drifting southward into Arkansas, torrential rainfall rates produced flooding in Naylor.

Flood · May 26, 2024. The second major severe weather outbreak for the month occurred on the 26th for the Quad State region. On the synoptic scale, a shortwave trough centered in the middle of the country with a 60 kt mid-level jet moved across northern Arkansas. A weak surface low was moving into SE Missouri during the morning with a secondary low located further northwest. A warm frontal boundary was draped across our area. A bowing…

Many locations further west and north from West Plains to Hillsboro in Missouri reached 7 to 10 inches of rainfall. Street flooding was report…

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 Ripley County

If a building in Ripley 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.
