Those traveling through Portage Valley and Turnagain Pass Saturday afternoon and evening or Sunday should be prepared for heavy snow, strong winds and poor visibility.

An earlier Blizzard Watch was updated to a Winter Weather Advisory Friday morning for those areas from Saturday afternoon until 9 a.m. Sunday. The storm is anticipated to bring 6 to 12 inches of snow, winds from the east at 30 to 50 mph and visibilities of less than one quarter mile.

The Cook Inlet, Anchorage Bowl and Valley will likely only see clouds, flurries, and a chance for light snow showers.

This storm system is currently in the western Aleutians and will track east into Southcentral Alaska over the next 24 to 48 hours.

Clouds will begin to increase ahead of the storm late Friday across Southcentral, but no precipitation is expected until early Saturday near Homer and Seward, late Saturday morning near Whittier and Girdwood and Saturday afternoon near Cordova and Valdez.

The heaviest snow will fall late Saturday night into Sunday morning.

As this storm moves in, it will also bring warmer air to the area. Kodiak will likely climb to the upper 30s and low 40s Saturday. Homer, Seward and Whittier will likely do the same on Sunday. Girdwood will return to the mid 30s, but most of Southcentral should stay at or below freezing through the weekend.

This storm will eventually bring snow and rain to Southeast Alaska Sunday night and Monday.
