An amplified pattern with high pressure to the north and low pressure to the south is forcing high winds from the Bering Sea Coast to the Copper River Basin. The wind will gradually taper off Saturday afternoon in the Mat-Su and in Anchorage, although high winds should be expected through Saturday morning. A Blizzard warning is in effect through 9 a.m. Saturday from Wasilla east to Chickaloon.
4:50 p.m. Friday - Parks Hwy. closed; parts of Mat-Su still without power
According to a dispatch from the Wasilla Police Department, the Palmer-Wasilla Highway is closed in both directions.
Meanwhile, several blocks of the Mat-Su Valley remain in the middle of a prolonged power outage, according to MEA. Over 6,000 homes and businesses – or roughly 10 percent – are without power in the areas of Wasilla proper and Knik/Goose Bay. Overall, about 7,300 (11 percent) of the company’s customers have no power.
The Anchorage area is almost entirely powered back on. After reporting close to 5,000 outages this morning in its service area, Chugach Electric now shows only 30 locations without power, less than 1 percent.
12:45 p.m. Friday - Authorities advise public to avoid dangerous driving conditions along Glenn Highway.
Alaska State Troopers have advised drivers in Anchorage and the Matanuska and Susitna valleys to avoid travel if possible due to the high winds and blowing snow.
With a peak wind gust of 83 mph, which qualifies as hurricane-force winds, being reported near Palmer, the windy weather has created dangerous snow drifts by scattering the record amount of snow that fell on the region in the weeks prior.
Driving conditions across the Mat-Su Valley are extremely challenging this morning due to blowing snow and snow drifts on major roadways across the region. Please do not go out today unless absolutely necessary. (1/2)— Alaska State Troopers (@akstatetrooper) December 23, 2022
Additionally, Matanuska Electric Association was reporting nearly 30% of its customer base without power as of 12:30p.m. Friday, according to its outage map, but the company has since restored power to many customers in the areas most affected, including the greater Palmer and Butte communities.

Over 10,000 more MEA customers are without power, according to the MEA outage map. The map tallies over 19,000 outages just after 11 a.m. MEA reported in a Facebook post of losing a second transmission line that serves Butte, Palmer, Sutton and Glacierview.
Much of the power has been restored to Anchorage-area businesses and homes. Chugach Electric has less than 300 customers without power, restoring over 4,000 outages in the last hour and a half.
9:30 a.m. Friday - MEA, Chugach Electric customers dealing with outages
More than 4,700 Chugach Electric customers are without power in Anchorage, according to the company’s outage map. The majority of the outages are around the Sand Lake and Jewel Lake areas, where 2,183 and 2,105 customers are without power, respectively.
More than 6,700 Matanuska Electric Association customers were without power as of 9:30 a.m., according to the company’s outage map. The majority of the outages are along the highway between Wasilla and Palmer, around Chugiak, and in Eagle River. Those three areas account for nearly 4,500 of the outages.
MEA said in a Facebook post that a transmission line problem zapped power to the LaZelle substation in the region around the Palmer-Wasilla and Parks highways, leaving over 83% of customers without power, according to the company.
The company said bucket trucks dispatched to solve the outages have been slowed by the high winds and snow drifts, making outage times longer than usual.
5 a.m. Friday - Thousands without power in Mat-Su
As of 5 a.m. Friday, over 5,500 MEA customers were without power, according to the company’s outage map. Most of those — about 3,374 — were from the Big Lake area, accounting for nearly all residents in that region, and at one point said close to 4,500 homes were without power.
MEA said in an update around 5:45 a.m. that most customers in the Big Lake area had power restored after crews were able to reroute power after discovering that an entire substation was down. The company said that no obvious cause was discovered for the outage but suggested that power lines slapping together could be the cause.
The company was also reporting almost half of all Point McKenzie residents, or 153 of 332, were without power.
Wind gusts of up to 53 mph were reported in Palmer, according to the National Weather Service, and gusts of up to 65 mph were expected in areas of the Valley.

The company also said that about 2,100 members lost power earlier in the night along Knik-Goose Bay Road, and crews were dispatched there to determine a cause for the outage.
