...Flash Flooding Possible Mainly Sunday Night into Monday for
Northwestern Portions of Alabama...

The risk for flash flooding will increase on Sunday night and Monday
as the remnants of Tropical Storm Barry move across the Mississippi
Valley. The main core of heaviest precipitation will likely occur
farther to our west as Barry moves northward into the interior South
and then curves northeastward into the Tennessee and Ohio Valleys.
Nevertheless, the main outer bands are expected to brush by
northwestern Alabama and cause increased chances for showers and
thunderstorms, especially from Sunday night into Monday. Due to the
tropical nature of the air mass, some of the thunderstorms will be
capable of producing heavy rainfall rates and the potential for flash
flooding. Further training of cells across the same areas, which can
tend to occur in these systems, may exacerbate the threat for
flooding. Rainfall may exceed three or four inches in northwestern
Alabama during this period. Rainfall amounts are expected to be lower
across northeastern portions of Alabama and southern Middle
Tennessee. However, the exact track of Barry is still uncertain and
thus rainfall amounts may still change.

A Flash Flood Watch may be required for portions of Northern Alabama
and southern Middle Tennessee for Sunday Night and Monday, and
potentially beyond, depending on the track of the system. Consult
future forecast products from the National Weather Service.
