ANCHORAGE, Alaska — Blizzard Warnings are in effect today for the Bristol Bay region, the eastern Aleutians and Alaska Peninsula, the eastern and northern portion of the Kenai Peninsula, Thompson Pass near Valdez, Turnagain Arm and the Upper Hillside of Anchorage, and the Kackemak Bay region.
Wind gusts to 70 mph have already been reported at Portage. Gusts of 80-90 mph are likely today and tonight for Portage, down Turnagain Arm, the Upper Hillside of Anchorage, and channeled terrain of PWS, especially near Cordova.
Here is the time line I laid out yesterday for this storm system:
Today-Tonight: The low reaches maximum strength of 948 mb which is a compatible central pressure to many hurricanes. Strong winds spread into the Panhandle and heavy rain increases throughout the day. In Southcentral, a Chinook wind develops in Anchorage late. Blizzard conditions persist in PWS and the eastern Kenai Peninsula. Periods of heavy rain and snow and hurricane force winds through channeled terrain, like Portage and Turnagain Arm, will remain into early Thursday morning. Strong winds and periods of snow on the backside of the low persist in Southwest. The Alaska Peninsula sees blizzard conditions into the afternoon, then colder air, lighter winds, and waning snow showers through the overnight. Highs rocket into the 20s, 30s, and 40s.
