The Different Types of Flooding That Can Occur In Central Alabama

Central Alabama is susceptible to flooding year-round due to its proximity to the Gulf of Mexico and the nearly unlimited supply of moisture it provides. In our case, this can occur from slow-moving summertime thunderstorms, a decaying tropical system, or large storm systems.

Sometimes floods develop slowly, and forecasters can anticipate where a flood will happen days before it occurs. Often times flash floods can occur within minutes.

Flooding is the most damaging, costly, and deadly severe weather-related phenomena, costing the United States over $5 billion in property damage yearly. On average, flooding is responsible for more deaths each year than lightning or tornadoes.

There are different types of floods that occur across Central Alabama…

Flash Flood

A Flash Flood is flooding that normally occurs within six hours of heavy or intense rainfall. These floods develop very quickly and are a significant threat to life and property.

Areal Flood

An Areal Flood develops more gradually, usually from prolonged and persistent moderate to heavy rainfall. These floods usually result in a gradual ponding or buildup of water in low-lying, flood-prone areas as well as small creeks and streams.

River Flood

A River Flood is flooding caused by a river or stream overflowing its banks due to recent heavy rainfall or prolonged rainfall over the drainage basin. This, in turns, inundates areas that are normally dry, such as low-lying areas near the river bank.
