...FLOOD WATCH REMAINS IN EFFECT THROUGH FRIDAY MORNING...

The Flood Watch continues for

* Portions of North Carolina and Virginia, including the
  following areas, in North Carolina, Alleghany NC, Ashe,
  Caswell, Rockingham, Stokes, Surry, Watauga, Wilkes, and
  Yadkin. In Virginia, Amherst, Appomattox, Bedford, Buckingham,
  Campbell, Carroll, Charlotte, Floyd, Franklin, Grayson,
  Halifax, Henry, Patrick, and Pittsylvania.

* Through Friday morning

* An extended period of rainfall with high rainfall rates and
  thunderstorms today and tonight will create favorable
  conditions for flooding. Rainfall totals of 3 to 4 inches with
  locally higher amounts over 5 inches possible along the Blue
  Ridge.

* The ground will be saturated when thunderstorms are most
  likely. High rainfall rates inside of these storms could
  potentially create rapid water rises, especially in small
  creeks and streams, areas with poor drainage, and low lying
  areas.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.
