Flash Flood Watches Issued for Monday

The NWS in Birmingham has issued a flash flood watch for North Central Alabama for Monday. It goes into effect at 6 am Monday. This join the flash flood watch that the NWS in Huntsville had already posted.

A fairly slow moving line of thunderstorms will traverse the state during the day on Monday. 1-2 inches of rain is possible, which potential aggravate flooding concerns with the already saturated ground and full lakes and rivers.

Many rivers across Central Alabama are already in flood and numerous flood warnings are already in effect.

Here is a display of all the flood watches in green and river flood warnings in bright green across Alabama and neighboring states.

Interestingly, there have been several water rescues today, of the lake and river variety. In Cherokee County, fire/rescue responded to rescue 11 people from campers due to lake flooding. And in Walker County, multiple residents in several homes are being rescued from rising flood waters along the Mulberry Fork.

SEVERE THREAT MONDAY
We will be tracking a QLCS, aka a squall line, or otherwise a line of severe thunderstorms, as it approaches Alabama early tomorrow. It should arrive in western counties around 8-10 a.m.

It will encounter a warm, moist airmass that is only slightly unstable, but should be sufficient to continue feeding the approaching thunderstorms, which are being forced by a strong cold front. There will certainly be a good supply of win shear, and this is leading to the fear of embedded tornadoes in the that line of storms.

Undoubtedly, at least a slight risk severe weather outlook will come out overnight and probably tornado watches will be in effect by the time you get your morning coffee. We will be monitoring the storms step by step as they cross the state, hoping for no repeat performances of the severe weather over the past week.

TRAGIC TOLL
More people have died in the past four days across the United States from tornadoes than had died the entire other 350 days of the year. Let’s not add to that tragic toll tomorrow. Please review your severe weather safety plans and stay abreast of developing weather conditions on Monday. Be in a place to receive warnings and act if one is issued for you.
