SUSITNA VALLEY

Areas Affected:
Northern Copper Valley - Northern Susitna Valley - Tok Cutoff
Effective: Sat, 12/6 12:19pm Updated: Sat, 12/6 8:40pm Urgency: Expected
Expires: Sun, 12/7 5:00am Severity:  Extreme  Certainty: Likely

 
Details:
* WHAT...Blizzard conditions due to blowing snow expected. Winds
gusting as high as 50 mph. Wind chills as low as 15 to 25 below
zero falling to as low as 25 to 40 below zero by Sunday.

* WHERE...Broad Pass, Richardson Highway from south of Isabel Pass
to Paxson, and along the Tok Cutoff from Mentasta Pass to north of
Gakona.

* WHEN...Until 9 PM AKST Sunday.

* IMPACTS...Travel could be very difficult. Frostbite may occur in
as little as 10 minutes to exposed skin. Blowing snow may reduce
visibility to as low as one quarter mile at times. This is
expected to be a prolonged blowing snow and cold weather event.

* ADDITIONAL DETAILS...An arctic airmass will continue to drive
colder air and strong winds south through the passes of the Alaska
Range through Sunday. The combination of snow already on the
ground and strong gap winds through the mountain passes will
likely lead to blowing snow that may severely reduce visibility.
The combination of wind and falling temperatures will result in
wind chill values as low as 25 below zero through Broad Pass and
40 below zero across the far northern Copper River Basin.

Information:
A Blizzard Warning means severe winter weather conditions are
expected or occurring. Blowing snow with strong winds and poor
visibilities are likely. This will lead to whiteout conditions,
making travel very hazardous. If you must travel, have a winter
survival kit with you. If you get stranded, stay with your vehicle.

If you must go outside, dress in layers. Several layers of clothes
will keep you warmer than a single heavy coat. Cover exposed skin to
reduce your risk of frostbite or hypothermia. Gloves, a scarf, and a
hat will keep you from losing your body heat.
