How Little River County floods

Flash flooding driven by heavy rainfall and slow-moving thunderstorms dominates the flood risk profile in Little River County, Arkansas. Over a recent 30-year period, NOAA records indicate 30 flash flood events, alongside 3 general floods resulting in 2 deaths and 1 tropical storm event.

Severe weather events have frequently impacted the region under conditions involving stalled warm fronts and upper-level low pressure systems. For example, a prolonged period of heavy rainfall caused flash flooding on October 4, 2023, as showers and thunderstorms with rainfall rates of one to three inches per hour trained across extreme Southwest Arkansas. Similarly, slow-moving storms produced heavy rainfall on August 12, 2020, following the development of a weak inverted surface trough along the Red River Valley.

Federal Emergency Management Agency records show that flood insurance claims have occurred in Zone X, averaging 3 inches of recorded water depth with an average payout of $40,752. Homeowners, real estate agents, and journalists should pay attention to properties located within Zone X and areas vulnerable to sudden, intense rainfall accumulation where localized flash flooding occurs.

From the storm reports

Flash Flood · Oct 4, 2023. A prolonged period of heavy rainfall occurred on October 4th across parts of extreme Southwest Arkansas. Showers and thunderstorms with 1-3 inch per hour rainfall rates trained in the vicinity of a warm front, which was draped across the Ark-La-Tex and in adjacent portions of Southeast Oklahoma and Northeast Louisiana. Deep convergence of moisture along the boundary resulted as the core of the low-level jet and as…

Flood · Jun 8, 2021. An upper low pressure system drifted north over Southeast Oklahoma and Western Arkansas during the early morning hours of June 7th, with an upper level disturbance beneath the attendant trough enhancing an area of showers and thunderstorms over Southwest Arkansas. A moist and unstable air mass was in place, with weak steering also present which resulted in slow-moving storms producing locally heavy rainfall. Rainf…

Flash Flood · May 16, 2020. A slow moving upper level low pressure system drifted east across Central and Eastern Texas during the daytime hours of May 16th. Meanwhile, the attendant surface low pressure system over East Central Texas drifted east into Northeast Texas during the afternoon, with a southerly low level jet allowing for a warm front to mix north into East Texas, extreme Northern Louisiana, into Southern Arkansas through the even…

Flash Flood · Aug 12, 2020. An upper level trough shifted southeast across Eastern Oklahoma and much of Arkansas during the early morning hours of August 12th, which helped to ignite scattered showers and thunderstorms over these areas. A weak inverted surface trough had developed along the Red River Valley of Southeast Oklahoma and extreme Northeast Texas, with a 25-30 kt southwesterly low level jet feeding near and atop this boundary along…

Flood insurance in Little River County

If a building in Little River 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.
