Update: Power companies have multiple crews working to restore power Wednesday morning in Anchorage and surrounding areas caused by the wind storm.
The Anchorage School District, Grace Christian, and UAA campuses in Anchorage, Eagle River-Chugiak, and JBER have canceled due to the power outages.
The Governor's office has announced that all "non-essential" state employees do not report to work.
Around 12:30 p.m., Chugach Electric spokesperson Sarah Wiggers said 6 to 9-thousand customers were without power and said power should be restored by Wednesday evening.
Wiggers said there are some isolated pockets without power and might take longer to restore depending on how long it takes to clear debris.
Chugach Electric said it has three major feeders to fix on the Hillside and Debarr areas early afternoon.
Chugach said it customers can now call and report locations that need repairs, so crews can spot and fix.
At 6:30 a.m., Chugach Electric said approximately 22,000 customers are without service. Multiple crew are "road hunting" down trees and lines.
Customers were asked to only call Chugach Electric if they see down lines that are a hazard earlier Wednesday morning.
Sarah Wiggers, with Chugach Electric, said the night darkness was making it hard for crews to located lines and "fingers crossed hoping noon will look a lot better for us."
Areas affected most by the outages under Chugach Electric were Debarr, Hillside, Boniface, Huffman, La Touche, O'Malley, Raspberry and Turnagain.
Around 10:30 a.m., Wiggers said 18,000 customers were without power. Chugach said crews were working to get feeders up and 16 were down earlier Wednesday morning and were down to 10 feeders.
Wiggers said Chugach Electric can focus on individual calls when crews are down to 4 feeders.
As of 10:45 a.m., Municipal Light and Power said most customers should have power back on and that the windstorm knocked out power to nearly all 30,000 customers Tuesday night.
Joint Base Elmendorf-Richardson said the "installation closed for today for non-essential personnel," and "this may not apply to all JBER organizations. Contact your supervisor if you are not sure."
Charter College said it will operate under a half-day session. President Richard McLean said Charter morning classes have been canceled and afternoon and evening sessions are still scheduled.
All ASD after-school activites have also been canceled.
Matanuska Electric Association report outages continue to affect areas throughout Eagle River and parts in Wasilla, Houston, Butte, Meadow Lakes, Lazy Mountain and Talkeetna.
MEA said trees falling on power lines or uprooted resulted in damage to both the "high-voltage transmission and low-voltage distribution systems" and about 5000 customers were without power as of 8:30 a.m. Wednesday.
Kevin Brown, MEA Communications Manager, said that 4,000 customers were without power as of 10:20 a.m. Wednesday.
