How Montgomery County floods

Flash floods from slow-moving thunderstorms dominate the flood history of Montgomery County, which recorded 41 flash flood events, 8 general floods, 4 tropical storms, and 3 tropical depressions over the last 30 years. Recent impacts include a prolonged all-hazards flooding event from slow-moving thunderstorms on April 6, 2025, and isolated flooding on August 23, 2025, when 4 to 5 inches of rain closed Meriwether Road in Pike Road.

National Flood Insurance Program records show claims across multiple zones, indicating risk extends beyond standard high-risk areas. Zone A accounted for 239 claims with an average payout of $21,257 and an average recorded water depth of 3 inches. Zone X recorded 130 claims with an average payout of $28,828 and an average recorded water depth of 15 inches. Additionally, Zone X_UNSHADED recorded 11 claims with an average payout of $42,019 and an average recorded water depth of 3 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located in Zone A and Zone X, as both areas have experienced significant claim volumes and substantial average water depths.

From the storm reports

Flash Flood · Aug 23, 2025. Thunderstorm activity over Elmore and Montgomery counties late on August 23 led to isolated flooding issues. Highway 14 west of Wetumpka had minor flooding after a couple inches of rain fell. Meanwhile, more extensive flooding took place around Meriwether Rd in Pike Road, with the roadway being closed after radar estimates of 4-5 of rain fell in the immediate area.

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…

Flood · Feb 13, 2024. A slow-moving storm system brought several inches of rainfall to most of Central Alabama from early morning on February 11 through the evening of February 12. While most areas saw at least 1-2 inches of rain, parts of southern and southeastern Central Alabama recorded as much as 8 inches, especially across parts of Lee, Macon, and Russell counties. Waves of heavy rainfall resulted in flooding along the Interstate…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley.

Flood insurance in Montgomery County

If a building in Montgomery 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.
