This Hazardous Weather Outlook is for portions of southwest North
Carolina...east Tennessee and southwest Virginia.

.DAY ONE...Today and Tonight

Extremely high winds are occurring across the mountains and
foothills of East Tennessee this morning. Wind gusts up to 85 mph
are expected, potentially higher in some locations that are prone
to high winds. These high winds will continue into the afternoon,
then decrease tonight but remain strong. In the Cumberland
Plateau, Tennessee Valley, and southwest Virginia, strong winds
with gusts up to 50 mph are expected to today and tonight. See the
High Wind Warning and Wind Advisory for details.

Heavy rainfall is also expected at times with this system this
morning, which may result in localized flooding. Refer to the
flood watch that has been issued for southwest North Carolina for
further details.

Light snowfall is possible in higher elevations of the northern
Cumberland Plateau, East Tennessee mountains, and southwest
Virginia tonight. Light accumulations will be most likely in the
mountains above 3,000 feet.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Additionally, strong wind gusts up to 40 mph are possible Tuesday
night into Wednesday morning in the valley, especially north of
Interstate 40. Winds may gust higher than 40 mph in the
mountains.

Another strong system will affect the area Friday and Saturday.
Although details are uncertain this far out, this system may have
the potential to produce high winds in the mountains, as well as
heavy rainfall for much of the area.

Early next week expect very cold temperatures to move into the
region. Overnight lows are expected to drop into the teens or
single digits by Tuesday morning, and wind chill values will make
it feel even colder.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not needed at this time.
