…Heavy Rainfall Expected Monday through Tuesday Combination of
Stalled Frontal Systems and Outer Effects of Tropical Storm
Isaias…

.Significant amounts of rainfall are expected to begin across the
forecast area after midnight tonight and increase through the day
Monday into Tuesday as a result of a stalled frontal system
across the area, firmly entrenched deep tropical moisture, and
the outer circulation of now Tropical Storm Isaias moving
northward from along the central and northern Florida East Coast
today to just east of Danville by Tuesday morning. Upslope east
flow along the Blue Ridge later tonight and Monday combined with
an increasing fetch of tropical moisture associated with the
outer circulation of Isaias as it moves northward and then
further enhanced with disturbances aloft and the proximity of the
stalled frontal system over the area could lead to excessive
amounts of rainfall across parts of the forecast area. One area
that seems likely to see excessive amounts of rain, in the 2-
4 inch range, are the eastern slopes of Blue Ridge Mountains,
particularly from Watauga County NC northeastward toward
Rockbridge County VA. The other area that could see excessive
amounts of rain will be Southside Virginia into the Virginia and
North Carolina Piedmont or roughly the Danville, Lynchburg,
Martinsville, and Reidsville areas as the core of Isaias passes
just east of Danville early Tuesday. In these areas, 2-4 inches of
rain are likely through Tuesday with locally higher amounts. Most
of the rain in this area will occur Monday afternoon through
Tuesday morning.

Small creeks and streams could rise into flood quickly by Monday
afternoon in areas of heavy rainfall. The Watauga River and its
tributaries in western NC will be subject to flooding as early as
Monday morning. Larger main stem river flooding is less likely,
but at least minor flooding could be expected on the Dan River
basin and its tributaries later in the week.
