How Madison County floods

Flash flooding from severe storms dominates Madison County's flood risk, accounting for 60 events and 7 deaths over the last 30 years. NOAA storm records illustrate this hazard, noting that strong to severe thunderstorms produced heavy rainfall across northwestern Arkansas during an unseasonably moist and unstable air mass in events such as November 2024.

National Flood Insurance Program records indicate that claims have been filed across multiple zones. Properties located in Zone A recorded 4 claims with an average payout of $16,585 and an average recorded water depth of 6 inches. Properties in Zone X recorded 2 claims with an average payout of $39,364 and an average recorded water depth of 2 inches, while 1 claim with an average payout of $601 and an average recorded water depth of 0 inches was logged in an unknown zone.

Homeowners, real estate agents, and journalists should pay the most attention to properties situated in Zone A and Zone X, where historical claims demonstrate that structures have sustained flood damages ranging from minor water accumulation to significant depths during severe storm events.

From the storm reports

Flash Flood · Nov 4, 2024. Strong to severe thunderstorms developed into and across northwestern Arkansas during the afternoon of the 4th, in an unseasonably moist and unstable air mass ahead of an approaching cold front. The atmosphere became very unstable ahead of the thunderstorms. The deep-layer and low-level wind shear strengthened during the afternoon, in response to a strong storm system translating into the Southern Plains from the…

Flash Flood · Apr 13, 2022. A line of thunderstorms developed into northwestern Arkansas during the morning of the 13th, as a cold front moved into the area. A strong thunderstorm within the line produced hail up to nickel size. More impactfully, this line of showers and thunderstorms was slow-moving, with individual cells within the line moving northeasterly repeatedly across the same areas, which resulted in locally heavy rainfall. Two to…

Flash Flood · Feb 7, 2019. A strong cold front moved through the region during the early morning hours of the 7th. Strong thunderstorms occurred along and ahead of the front, with a few of the storms producing severe wind gusts.

Flash Flood · Mar 27, 2018. Widespread thunderstorms developed across eastern Oklahoma during the evening of the 26th as a cold front moved into the area. These thunderstorms slowly spread into northwestern Arkansas during the morning of the 27th. The strongest storms produced a tornado and damaging wind gusts across portions of west-central Arkansas. The heavy rainfall from these thunderstorms resulted in isolated flash flooding across port…

Flood insurance in Madison County

If a building in Madison 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.
