How Wilbarger County floods

Flash flooding from slow-moving storms and training weather systems dominates the flood character of Wilbarger County. Over the last 30 years, the NOAA Storm Events Database recorded 14 flash flood events compared to 4 general flood events.

Recent occurrences illustrate this pattern. On May 19, 2018, storms moving southeast from Oklahoma produced training that resulted in flooding. Similarly, on March 28, 2017, slow-moving storms and extensive shower coverage formed across Oklahoma and western north Texas, leading to flash flooding alongside severe weather and a tornado.

National Flood Insurance Program records indicate that property owners in designated flood hazard areas face significant risk. Specifically, properties in Zone A averaged payouts of $45,000 with an average recorded water depth of 12 inches. Properties with unknown zone designations averaged $20,273 per claim with an average recorded water depth of 5 inches. Homeowners and real estate professionals should pay the closest attention to properties located within Zone A and areas lacking clear flood zone determinations.

From the storm reports

Flash Flood · May 19, 2018. An area of storms formed across Oklahoma along and around a stationary front (several other lingering boundaries contributed as well) on the afternoon of the 19th. These storms moved southeast into the night with some training resulting in flooding.

Flash Flood · Mar 28, 2017. An area of storms formed across Oklahoma and western north Texas in the vicinity of several fronts/boundaries overnight on the 28th into early 29th. Besides severe weather and a tornado, slow moving storms and extensive shower coverage also led to flash flooding.

Flash Flood · May 18, 2017. A line of storms fired along and just ahead of a dryline and cold front on the afternoon of the 18th and continued eastward across the state overnight into the 19th.

Flash Flood · Jun 2, 2017. An area of thunderstorms formed in the early morning in central Texas, then expanded into southwest Oklahoma early on the 2nd. With high rain rates, these storms produced flash flooding.

Flood insurance in Wilbarger County

If a building in Wilbarger 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.
