How Noble County floods

Flash flooding from heavy rainfall events dominates the flood profile of Noble County, Oklahoma, accounting for 17 of the 19 recorded flood events over the past 30 years alongside two general flood events. Severe weather and heavy rainfall have triggered these incidents under unstable atmospheric conditions. For example, an extremely unstable environment caused widespread severe weather and flooding on May 21, 2019, while training showers and storms near a stalled front caused flash flooding on October 4, 2017.

Historical National Flood Insurance Program records indicate minimal claims activity across the county. Zone A properties have recorded two claims with an average payout of $11,056 and an average recorded water depth of 1 inch. Zone X has recorded one claim with an average payout of $0 and an average recorded water depth of 0 inches, and Zone X unshaded has recorded one claim with an average payout of $153 and an average recorded water depth of 0 inches.

Homeowners, real estate agents, and journalists should pay the most attention to properties located within Zone A, as these areas have experienced the highest average payouts and recorded water depths associated with local flood events.

Flood insurance in Noble County

If a building in Noble 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.
