How Jackson County floods

Flash flooding from severe storms dominates the local flood profile, accounting for 26 of the 31 total recorded flood events over the last 30 years alongside 5 general flood events. Recent events illustrate this pattern, including severe convection and heavy rainfall that produced significant flash flooding from April 29 to April 30, 2025, as well as multiple rounds of storms driven by a nocturnal low-level jet that caused flash flooding on May 23, 2024. Additional flooding occurred on May 31, 2022, due to slow-moving storms along a stationary boundary, and on March 18, 2020, following an upper-level wave that generated numerous thunderstorms.

National Flood Insurance Program records show claims filed across multiple zones, with Zone A recording 5 claims averaging a payout of $2,014 and an average recorded water depth of 2 inches. Zone X recorded 1 claim with an average payout of $0 and an average recorded water depth of 0 inches, while Zone X unshaded recorded 1 claim with an average payout of $475 and an average recorded water depth of 1 inch. Homeowners, real estate agents, and journalists should pay the most attention to properties located in Zone A where claims and water depths are highest.

From the storm reports

Flood · Apr 30, 2025. Multiple rounds of severe convection and flooding occurred from the predawn hours of the 29th into morning hours of the 30th. The most significant round of severe thunderstorm activity occurred across portions of western-north Texas on the evening of the 29th, where intense supercell thunderstorms produced very large hail, damaging wind gusts and a pair of significant (EF-2+) tornadoes. Significant flash flooding…

Flash Flood · May 23, 2024. Two primary rounds of severe convection occurred on the 23rd, with the first during the initial hours of the morning and the second during the early into late evening. The early morning round was fostered (in part) by a nocturnal low-level jet/ascent across portions of southwestern into south-central Oklahoma. Multiple reports of hail, including a few of severe-caliber, were received with this activity. ||A more i…

Flash Flood · May 31, 2022. Storms developed along a stationary boundary in northwestern Oklahoma into the Texas panhandle during the afternoon and evening of the 31st. Slow storm motions led to very heavy rainfall and flooding in some locations. Intense winds close to 80 mph, large hail, and a few tornadoes were also reported.

Flash Flood · Mar 18, 2020. A strong upper level wave provided lift for numerous thunderstorms to develop, with several rounds of storms leading to scattered reports of hail, wind, and flooding on the 18th into early on the 19th.

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.

Flood insurance in Jackson County

If a building in Jackson 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.
