NWS Huntsville has issued a Flash Flood Watch that goes into effect at 9:00 PM Tuesday until 12:00 PM Wednesday for all counties in North Alabama. Those counties include…
Colbert, Cullman, De Kalb, Franklin, Jackson, Lauderdale, Lawrence, Limestone, Madison, Marshall, and Morgan.
Heavy rainfall is expected to start tonight and going into Wednesday morning. The combination of a warm front lifting into the area and low pressure system approaching from the west will produce widespread showers and thunderstorms, some with heavy rainfall, from this evening into Wednesday morning. Rainfall amounts of 2 to 3 inches are likely over most of the area, with locally higher amounts possible. The resulting excessive runoff may lead to flash flooding, particularly in poor drainage areas and low water crossings.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
