How Winston County floods

Flash flooding from heavy rainfall events dominates the flood risk profile in Winston County, Alabama, accounting for 18 of the past 30 years of recorded events, alongside occasional tropical systems.

Severe weather patterns drive these flood occurrences, as demonstrated by heavy rainfall from slow-moving thunderstorms in February 2022 and widespread saturated ground conditions following prolonged tropical moisture streams in July 2013. Historical FEMA National Flood Insurance Program records indicate that flood claims are concentrated in designated flood zones. Specifically, Zone A properties have recorded 7 claims with an average payout of $32,410 and an average recorded water depth of 6 inches. Zone X properties have recorded 4 claims with an average payout of $0 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, where actual insurance payouts and recorded water depths confirm a historical risk of structural flooding.

From the storm reports

Flash Flood · Apr 6, 2025. Deep-layer ridging over the Southeast United States held up a trough over the Central United States for the first few days of April, leading to a prolonged and significant severe weather and flooding event from Texas to Ohio and West Virginia along a stalled boundary. As the ridge began to retreat eastward, a cold front slowly progressed through Central Alabama on April 6, with an all-hazards weather event unfoldi…

Flash Flood · Feb 23, 2022. A line of thunderstorms ahead of a slow moving cold front produced periods of heavy rainfall over a several period over the northwest portions of central Alabama. Rainfall totals averaged 2-3 inches.

Flash Flood · Dec 25, 2015. A low level boundary across southeast Alabama became the focus for heavy rainfall and severe weather during the early morning hours of December 24th. As the boundary lifted northward, the focus for heavy rainfall and severe weather shifted into north central Alabama.

Flash Flood · Jul 5, 2013. The first week of July 2013 was a wet one as a plume of tropical moisture streamed northward from the Gulf of Mexico, across the southeastern United States, and northeastward along the Appalachians. With a persistent mid level trough to its west and a ridge to its east, this stream of moisture continued for many days. Precipitable water values reached over two inches locally and after several days of widespread ra…

Flood insurance in Winston County

If a building in Winston 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.
