...Introduction...

During the past two weeks, west North Carolina and southwest Virginia had 1 to
2 inches of rainfall but most of this occurred early in the period. Drier
conditions have prevailed over the past 10 days. The area rivers continue to
recede and no flooding is forecast over the next several days. Warm temperatures
have melted any remaining snow over the higher elevations.

Region wide...streamflow and soil moisture values are above seasonal averages in
west North Carolina and near seasonal averages in southwest Virginia.

The current precipitation forecast for the next seven days indicates widespread
mean areal amounts of 1 to 2 inches of rainfall over southwest Virginia and west
North Carolina.

...French Broad/Upper Pigeon...Little Tennessee...Tuckasegee
...and Hiwassee Basins (WFO GSP)...

Streamflow and soil moisture content are above seasonal levels. All area rivers
are receding and no flooding is forecast over the next several days. Observed
daily streamflows as a percent of mean are given below.
