ALASKA SNOW REPORT

* WHAT...Snow and blowing snow expected. Total snow accumulations 4 to 12 inches. Lowest amounts from Glennallen west. Highest amounts south and east of Glennallen. Winds gusting as high as 35 mph on Saturday. * WHERE...Central Copper Valley, Ernestine, Eureka / Tahneta Pass, McCarthy, Southern Copper Valley, and Western Copper Valley. * WHEN...From 5 PM this afternoon to 5 PM AKST Saturday. * IMPACTS...Travel could be very difficult. Blowing snow Friday night and Saturday could reduce visibility to as low as one half mile at times. * ADDITIONAL DETAILS...A long duration snow event will begin over the southern half of the Copper River Basin by this evening. The first round of light to moderate snow will likely persist through around noon Friday before possibly tapering off for a time Friday afternoon. A second round of snow is then expected to develop by Friday evening and continue through Saturday afternoon. Northerly winds will also increase Friday night through Saturday as colder air moves into the basin. The snow will become light and powdery by Saturday, with the combination of snow and wind likely leading to areas of blowing snow that could significantly reduce visibility.

* WHAT...Blizzard conditions possible. Total snow accumulations between 8 and 16 inches possible. Winds could gust as high as 55 mph. Wind chills falling to as low as 35 below zero by Sunday morning. * WHERE...Thompson Pass. * WHEN...From Friday morning through Sunday morning. * IMPACTS...Visibilities reduced to one quarter mile or less due to snow and blowing snow. Travel could be very difficult. Frostbite may occur in as little as 10 minutes on exposed skin. * ADDITIONAL DETAILS...An arctic airmass will drive colder air and strong winds through Thompson Pass beginning Friday. The combination of snow already on the ground, along with additional snowfall expected and strong gap winds, will likely lead to snow and blowing snow that may severely reduce visibility. Snow is likely to taper off starting Sunday morning. However, gusty winds will persist.

* WHAT...Mixed precipitation and snow. Additional snow accumulations of 1 to 3 inches and ice accumulations of a light glaze. Locally higher snowfall amounts are possible along the Anchorage Hillside northeast to Eagle River and Palmer. * WHERE...Anchorage / Eagle River (all elevations), and Lower Matanuska Valley. * WHEN...Until 7 AM AKST Friday. * IMPACTS...Roads, and especially bridges and overpasses, will likely become slick and hazardous. Travel could be very difficult. The hazardous conditions could impact the Thursday evening and Friday morning commutes. * ADDITIONAL DETAILS...A mix of snow, freezing rain and sleet will slowly transition to mainly snow this evening into tonight. Periods of moderate snowfall rates are possible overnight through early Friday, especially along parts of the Anchorage Hillside north to Eagle River and Palmer. Snow will taper off by mid morning on Friday.

* WHAT...Heavy snow possible. Total snow accumulations up to 3 inches possible. Winds could gust as high as 40 mph. * 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...From Friday evening through Sunday evening. * 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 may be a prolonged blowing snow and cold weather event. * ADDITIONAL DETAILS...An arctic airmass will drive colder air and strong winds south through the passes of the Alaska Range late Friday 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.

...SNOW FOR THE NORTHERN PANHANDLE THIS WEEKEND... .A pattern change will bring colder temperatures and strong outflow winds extending southward starting Friday night. Forecast confidence is increasing that this pattern change, in combination with prolonged moisture, will produce accumulating heavy snow for the highways and communities of the northern panhandle, including the Klondike and Haines Highways, as well as the cities of Haines and Skagway. Forecast confidence is not high enough for warning level snowfall moving toward Juneau and the Icy Strait Corridor, though the forecast continues to be monitored and updated through the week. Cold temperatures are expected to continue to spread southward into early next week, increasing potential for a long duration snowfall event. * WHAT...Heavy snow possible. Total snow accumulations of 9 to 15 inches possible. * WHERE...Municipality of Skagway and Haines Borough and Klukwan. * WHEN...From late Friday night through late Saturday night. * IMPACTS...Travel could be very difficult and is discouraged. * ADDITIONAL DETAILS...Long duration snowfall will begin Friday evening and continue through the weekend, with heaviest rates expected Friday night into Saturday morning.
