From the storm reports

Flash Flood · Mar 27, 2023. A multi-day severe weather event produced all modes of severe weather across Central Alabama. An upper low parked over the Midwest States and an upper ridge over the Florida Peninsula produced a deep layer of moisture and shear over Alabama. A slow moving surface cold front provided the focus for severe storms late Saturday night and continuing through Monday morning.

Flash Flood · Sep 19, 2021. A tropical air mass covered Alabama on September 18-19 with precipitable water values over 2 inches. An nearly stationary upper low near the Texas and Louisiana state line provided lift and instability for showers and thunderstorms across the Central Gulf States. An inverted surface trough was located along the I-20 corridor on September 18th, and provided a focus for slow moving thunderstorms that produced flash…

Tropical Storm · Oct 29, 2020. Tropical cyclone Zeta developed over the Western Caribbean Sea on Saturday, October 24, and slowly moved west. The tropical storm emerged into the Southern Gulf of Mexico on Tuesday, October 27th. Zeta turned northwest and became a hurricane on Wednesday, October 28th. Zeta made landfall in southeast Louisiana late on Wednesday, then moved northeast into southwest Alabama late Wednesday night. The hurricane weaken…

Tropical Storm · Sep 11, 2017. Hurricane Irma made landfall on the west coast of the Florida peninsula on September 10th. The hurricane tracked northward across Florida and weakened into a tropical storm on September 11th as it moved into southwest Georgia Tropical Storm Warnings were in effect for east central Alabama as Tropical Storm Irma approached east Alabama. Steady rains overspread the region by early morning, with breezy and gusty win…

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. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Tallapoosa County

If a building in Tallapoosa 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.
