How Howell County floods

Flash flooding from heavy rainfall dominates the flood risk profile in Howell County, accounting for 195 events and 6 deaths over the last 30 years alongside 107 standard flood events.

Recent history illustrates this severe hazard. Multiple rounds of storms between April 4th and April 6th, 2025, dropped 8 to 10 inches of rain—with localized amounts up to 12 inches—across southern Missouri, causing significant flash flooding, minor to moderate river flooding, and two fatalities in West Plains. Additional flash flooding occurred during early morning thunderstorms on June 29, 2025.

National Flood Insurance Program records highlight distinct risk tiers across property types. Zone A properties face the heaviest impact, accounting for 60 claims with an average payout of $67,543 and an average recorded water depth of 3 inches. Properties in Zone X have recorded 10 claims with an average payout of $16,086 and an average water depth of 2 inches. Zone X_UNSHADED properties recorded 3 claims averaging $6384 with an average water depth of 0 inches, while Zone UNKNOWN recorded 2 claims averaging $217 with an average water depth of 1 inch. Homeowners, real estate agents, and journalists should pay the closest attention to properties located within high-risk Zone A, where average payouts and water depths are significantly higher than in other zones.

Flash Flood · Apr 20, 2025. A strong storm system moved through the area on Sunday April 20th, 2025. This system brought tornadoes, damaging wind, large hail and heavy rain. The heavy rainfall led to flooding as the area had already received heavy rainfall from storms earlier in the week. Multiple area rivers reached minor to moderate flood stage due to heavy runoff.

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 Howell County

If a building in Howell 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.
