Flash flooding driven by severe storm systems and heavy rainfall dominates the flood risk profile in Tishomingo County. Over the past 30 years, the NOAA Storm Events Database recorded 21 flash flood events resulting in 3 deaths, alongside 1 general flood event and 1 tropical storm. Recent activity includes heavy rain and training storms from a frontal boundary in April 2025, as well as slow-moving storms producing localized flash flooding in June 2025, following severe thunderstorm development in March 2025.
National Flood Insurance Program claims data demonstrate that flood risks extend across multiple zones. Properties in Zone A account for 12 claims with an average payout of $13,279 and an average recorded water depth of 1 inch. Meanwhile, properties in Zone X recorded 5 claims with a higher average payout of $32,356 and an average water depth of 1 inch. An additional claim in an unknown zone resulted in a $7,177 average payout with an average water depth of 2 inches.
Homeowners and real estate agents with properties located in designated Zone A, as well as those in Zone X where higher claim payouts indicate significant vulnerability to surface water and storm-driven flooding, should pay the closest attention to these risks.

Flash Flood · Apr 23, 2025. A slow moving cluster of convection continued to back build bringing torrential rainfall rates to the MS/AL county line. Estimated rates neared 5 inches over 3 hours.
Flash Flood · Jun 17, 2025. Precipitable water values remain high along and east of the Mississippi River, around 2 inches. Isolated slow-moving storms produced localized heavy rainfall and a couple of instances of flash flooding.
Flood · Mar 15, 2025. An upper low over the Central Plains moved into the Upper Mississippi Valley during the evening hours of Friday, March 14, 2025. Increasing moisture advection ahead of an approaching cold front lifted dewpoints into the low to mid 60s. This coupled with increasing height falls and a mid-level 80 knot jet rotating around the main upper low supported severe thunderstorm development. Large looping hodographs, MLCAPE…

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Tishomingo 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.
