How Comanche County floods

Flash flooding from slow-moving summer thunderstorms and saturated atmospheres dominates the flood history of Comanche County. Over the last thirty years, NOAA records document 38 flash flood events resulting in one death, alongside 13 general flood events causing two deaths. Slow storm motions and repeated storm training over the same areas have frequently driven these incidents, as seen during the heavy rainfall and flooding events in May 2016 and September 2020, as well as multiple flash flooding events in July 2025 caused by a lingering upper trough.

Federal insurance records reflect property damage across multiple flood zones. Zone A accounts for the highest claim frequency with 9 claims averaging $1,817 and an average recorded water depth of 1 inch. Single claims were also recorded in Zone X, Zone X_UNSHADED, and an unknown zone, with average payouts ranging from $3,723 to $30,000 and average recorded water depths reaching up to 120 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within FEMA-designated Zone A, which experiences the most frequent flood claims, as well as any properties situated in unshaded or poorly defined zones where higher water depths and larger average payouts have been recorded during severe storm events.

From the storm reports

Flash Flood · Jul 6, 2025. From the July 4th weekend into the early part of the following week, a weak upper trough lingered over North and Central Texas, triggering several days of scattered showers and thunderstorms. A saturated atmosphere combined with slow storm motions resulted in numerous flash flooding events throughout the region, particularly in Central Texas.

Flood · Sep 2, 2020. An upper level trough moved very slowly from the Rockies into the Plains during the first week of September, resulting in several days of showers and thunderstorms. Many storms became strong with gusty winds and hail, but the primary result was heavy rain and flooding. Unfortunately, a couple died in Temple Texas in a house fire that was started by lightning.

Flood · May 27, 2016. A series of upper level disturbances produced multiple rounds of showers and thunderstorms across the region. A few storms became severe with large hail and damaging wind gusts, but storms training repeatedly over the same areas led to this being mostly a flood and flash flood event.

Flood insurance in Comanche County

If a building in Comanche 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.
