This Hazardous Weather Outlook is for portions of Southwest North
Carolina...East Tennessee and Southwest Virginia.

.DAY ONE...Today and Tonight

An approaching cold front will bring strong gusty winds to the
far east Tennessee and southwest Virginia Mountains and
adjacent foothills today and tonight. Sustained winds of 25-40
mph with gusts up to 50 mph are expected across the Smoky
Mountains and adjacent foothills which could result in tree damage
and a few power outages.

A broad area of moderate to heavy showers will move into the
region today. Given the saturated ground from recent rains,
pockets of flash flooding could occur. Use caution if traveling.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

A tight pressure gradient between the departing low pressure
system and arriving higher pressure should keep a healthy west to
northwesterly flow going well through the day Wednesday.
Wind speeds in the 15 to 25 mph range will be common, with gusts
to around 45 mph in this westerly flow regime behind the front.

The higher terrain across much of Southwest Virginia and the
mountains along the Tennessee and North Carolina border will see
the greatest impact from these post frontal winds.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated at this time.
