SOUTHWEST VIRGINIA...HAVE SIGNIFICANT SNOW STILL ON THE GROUND.
RAIN WILL CAUSE AT LEAST SOME OF THE SNOW TO MELT WHICH WILL ADD TO
THE RUNOFF. SMALL STREAMS COMING OUT OF THE MOUNTAINS...AND POSSIBLY
THE NORTHERN CUMBERLAND PLATEAU...WILL BE MOST LIKELY TO FLOOD. SOME
OF THE LARGER RIVERS SUCH AS THE FRENCH BROAD...LITTLE PIGEON...AND
PIGEON MAY ALSO FLOOD. EVEN THE UPPER REACHES OF THE POWELL AND
CLINCH RIVERS MAY EXPERIENCE SIGNIFICANT RISES.
URBAN AREAS SUCH AS CHATTANOOGA...KNOXVILLE...AND JOHNSON CITY MAY
