NWS Huntsville issues Flash Flood Watch for area until noon Wednesday

CULLMAN - The National Weather Service in Huntsville has issued a FLASH FLOOD WATCH from 9 p.m. tonight, Tuesday, Dec. 19 until noon on Wednesday, Dec. 20 for the counties of Colbert, Cullman, De Kalb, Franklin, Jackson, Lauderdale, Lawrence, Limestone, Madison, Marshall and Morgan in Alabama and in southern middle Tennessee for the counties of Franklin, Lincoln and Moore.

Heavy rainfall is expected tonight into Wednesday morning. The combination of a warm front lifting into the area and a low pressure system approaching from the west will produce widespread showers and thunderstorms, some with heavy rainfall, from this evening into Wednesday morning.

Periods of heavy showers and thunderstorms will overspread the area this evening and tonight and persist into the morning hours of Wednesday. 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.

Hazardous Weather Outlook

The threat for a few thunderstorms will begin to develop this evening and increase further overnight, as a storm system approaches the region from the southwest. A few strong to severe storms will be possible late tonight, mainly south of Highway 72. The main threat will be damaging winds around 60 mph.
