How Donley County floods

Flash flooding from convective storms dominates the flood risk in Donley County, accounting for 20 of the 25 recorded flood events over the last 30 years, alongside 5 general flood events.

Heavy rainfall linked to regional spring storm systems and unstable airmasses frequently triggers these conditions. For example, a potent upper-level system and sharpening dryline produced widespread hazards on March 13, 2021, while severe thunderstorms driven by daytime instability and low-level moisture caused minor flooding on May 23, 2020. An additional severe weather event occurred on April 22, 2025, amid a multi-day setup of thunderstorms across the Texas Panhandle.

Homeowners, journalists, and real estate agents should note that historical National Flood Insurance Program records for Zone A show 7 claims with an average payout of $1,794 and an average recorded water depth of 4 inches. Properties located within Zone A should pay the closest attention to these localized flood risks.

From the storm reports

Flood · Apr 22, 2025. Thunderstorms developed during the afternoon hours of April 22nd east of the dryline. The combination of instability, abundant low level moisture and wind shear allowed storms to become severe and produce hail up to ping pong ball size in the southeast Texas Panhandle. A similar setup occurred on April 23rd where the dryline was situated a little further west which allowed for storms to develop across more of the…

Flood · Mar 13, 2021. A very potent upper level system produced widespread hazards from heavy snow across the front range/Rockies to severe weather across the Southern High Plains. The vigorous closed upper low was approached the Four Corners region from the west. A warm front lifted north and northwest across all but the Oklahoma Panhandle and the northwest Texas Panhandle while a sharpening dryline was located over eastern New Mexico…

Flood · May 23, 2020. Scattered thunderstorms developed during the late afternoon and evening across eastern and central parts of the Texas Panhandle. The storms developed within a highly unstable and modestly sheared airmass along and ahead of the dryline. Some of these storms became severe across the southeast and south-central Texas Panhandle, producing large hail and gusts of 58 MPH or higher. One severe thunderstorm in the southea…

Flood · Apr 17, 2019. A cold front stalled across the Texas Panhandle, and was oriented from southwest to northeast over the region. The temperatures and moisture contrast along the front in-conjunction with a potent mid-level disturbance provided plenty of instability and lift for thunderstorms to develop. Sufficient wind shear allowed for supercells to develop and some of these storms produced large hail up to 2 in diameter and torna…

Flood insurance in Donley County

If a building in Donley 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.
