Winter Storm Watch issued January 8 at 10:21PM AKST until January 11 at 6:00AM AKST by NWS Anchorage AK

* WHAT...Heavy snow and blowing snow possible. Total snow accumulations between 5 and 10 inches possible. Winds could gust as high as 45 mph. * WHERE...Seward. * WHEN...From Friday afternoon through late Saturday night. * IMPACTS...Visibilities reduced to one quarter mile or less due to blowing snow. Travel could be very difficult. The hazardous conditions could impact the Friday evening commute. * ADDITIONAL DETAILS...Snow will begin by Friday afternoon and combine with gusty north winds to cause significant blowing snow and potential whiteout conditions. There is still a high degree of uncertainty regarding the track of a system moving in from the Gulf and for the timing and duration of heavier snowfall. Any shift in the low track could lead to higher or lower snowfall totals through Saturday night.

* WHAT...Heavy snow possible. Total snow accumulations between 6 and 30 inches possible. Highest snowfall totals expected at higher elevations and near Portage Valley. Winds could gust as high as 40 mph. * WHERE...East Turnagain Arm, SW Kenai Peninsula, NW Kenai Peninsula, Skilak Lake, Interior Kenai Peninsula, Turnagain Pass, and West Prince William Sound & Whittier. * WHEN...From Friday afternoon through Sunday morning. * IMPACTS...Whiteout conditions are possible and may make travel treacherous. Areas of blowing snow could significantly reduce visibility. The hazardous conditions could impact the Friday evening commute. * ADDITIONAL DETAILS...Snow will spread into the Kenai Peninsula and Turnagain Arm from southeast to northwest throughout the afternoon and evening on Friday and persist through Saturday, then gradually end through Sunday morning. Most locations will likely see total snowfall on the lower end of the expected range of amounts. A corridor of more intense snowfall is likely across portions of the Kenai Peninsula and Turnagain Arm. However, there remains a high degree of uncertainty regarding where this axis of heavier snow will develop.
