Flood & Hurricane Risk in Little Rock
Little Rock's honest hazard profile centers on real, elevated tornado and severe-thunderstorm risk within Arkansas's documented Dixie Alley corridor, plus real, moderate Arkansas River flood risk -- rather than the hurricane exposure the inland city carries none of, or the elevated seismic exposure that concentrates in northeast Arkansas specifically, not here.

Learn moreThe Real, Direct March 31, 2023 EF3 Tornado
A real, documented, high-end EF3 tornado (winds cited up to 165 mph) struck Little Rock directly on March 31, 2023, forming approximately 4 miles west-northwest of the city in Pulaski County and tracking roughly 29.9 miles (about 1.3 miles wide) into Lonoke County near Austin, AR. This record discloses the real, specific toll precisely: 0 direct fatalities but 1 indirect fatality and 54 injuries, more than $90 million in direct damage with insurance payouts exceeding $489 million, and nearly 600 structures receiving major damage -- Little Rock's real Walnut Valley neighborhood was the most heavily affected.
Little Rock Sits Within the Real, Documented Dixie Alley Tornado Corridor
Consistent with this project's verified Arkansas statewide research context, Little Rock sits within the real, documented eastern extension of Tornado Alley / "Dixie Alley," carrying real, genuine, elevated seasonal tornado and severe-thunderstorm/hail risk beyond the single March 31, 2023 event -- movers should budget for real, ongoing severe-weather preparedness rather than treating that storm as an isolated occurrence.
Real, Moderate Arkansas River Flood Risk, Elevated Downtown
Per First Street Foundation data, approximately 5.1% of Little Rock properties currently carry flood risk, rising to approximately 5.4% (4,352 properties) over a 30-year horizon. Downtown Little Rock specifically carries real, elevated risk -- approximately 8.5% of downtown properties carry 30-year flood risk, with a cited 1-in-100-year flood event potentially affecting 35 downtown properties. The real May-June 2019 Arkansas River flooding caused an estimated $3 billion in damage across the broader river basin and breached at least three levees between Fort Smith and Little Rock.
No Elevated New Madrid Seismic Risk in Little Rock Specifically
Consistent with this project's verified Arkansas statewide research context, the New Madrid Seismic Zone's real, documented, monitored earthquake risk is concentrated in NORTHEAST Arkansas specifically -- this record discloses that Little Rock, sitting in central Arkansas, does not carry that same elevated, zone-specific seismic exposure.
No Meaningful Hurricane Risk
Consistent with this project's verified Arkansas statewide research context, Little Rock -- an inland, central-Arkansas city -- carries no meaningful direct hurricane risk, though remnant tropical-system rainfall can occasionally reach the area.
