The Flooding Character of Ness County

Flash flooding from thunderstorms is the primary flood hazard in Ness County. Over the past 30 years, NOAA Storm Events data shows 10 flash flood events and 6 flood events. For example, a flash flood occurred on July 12, 2020, following boundary layer heating and an upper-level shortwave trough. Another flash flood event was reported on August 25, 2014, associated with a nearly stationary front.

While the National Flood Insurance Program (NFIP) has recorded only two claims in Zone A, with no financial payout or reported water depth, these events highlight the potential for flooding. Residents in areas designated as Zone A, particularly those without a Base Flood Elevation (BFE), should pay close attention to flood risk.
