How Crenshaw County floods

Flash flooding driven by heavy rainfall events dominates the flood risk profile of Crenshaw County, Alabama. Over a thirty-year period recorded by the NOAA Storm Events Database, the county experienced 17 flash flood events, alongside 3 tropical storms, 2 hurricanes, and 2 general floods.

Severe weather and tropical systems frequently bring heavy rainfall and inland flooding to the area. For example, a moist airmass ahead of a cold front caused heavy rain and flash flooding in February 2022. Additionally, slow-moving Hurricane Sally brought widespread freshwater flooding inland to south-central Alabama in September 2020, while rapidly moving Hurricane Zeta caused further impacts across the region in October 2020.

FEMA records indicate that National Flood Insurance Program claims in the county are concentrated in Zone A, which logged 2 claims with an average payout of $0 and an average recorded water depth of 0 inches. Property owners located within Zone A should pay the most attention to this flood risk data when evaluating their exposure.

Flash Flood · Feb 3, 2022. A very moist and unstable airmass developed ahead of an approaching cold front. Storms developed along the front and produced damaging wind gusts as they moved across southeast Mississippi and southwest Alabama. Heavy rain caused flooding across portions of the area.

Tropical Storm · Oct 28, 2020. Hurricane Zeta made landfall in southeast Louisiana during the late afternoon hours of Wednesday, October 28th as a strong category 2 hurricane with maximum sustained winds of 110 mph. Zeta quickly raced northeast and moved across inland southeast Mississippi and inland southwest Alabama during the evening hours. Shortly after midnight, Thursday, October 29th, Zeta weakened to a tropical storm while moving across…

Flash Flood · Sep 16, 2020. Hurricane Sally made landfall in Gulf Shores, AL at 5am on Wednesday, September 16th as a strong Category 2 hurricane with maximum sustained winds of 105 mph. Sally produced widespread wind, storm surge, and freshwater flooding across coastal AL and the western Florida Panhandle. Flood and wind damage also extended well inland into inland southwest Alabama and south central Alabama. Sally was an extremely slow mov…

Flood insurance in Crenshaw County

If a building in Crenshaw 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.
