| 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. For the latest road conditions call 5 1 1 or visit 511.alaska.gov. |
