An Alaska winter storm can bring heavy snow to one community and dangerous winds to another. The snowfall needed to trigger a Winter Storm Warning also varies by region. In parts of the Interior, 8 inches may meet the criteria, while many areas covered by the Anchorage office use a higher threshold. Knowing which warning applies to your town helps you prepare before roads close or the power goes out. This guide explains where to check alerts, how to read them, and what to keep powered during an outage. It's an evergreen preparedness guide, not a live forecast.
Is There a Snow Storm Warning in Alaska Right Now? Where to Check Alerts, Roads, and Power
News about an Alaska snowstorm can be out of date within hours, so check official alerts rather than relying on headlines. The National Weather Service (NWS), Alaska 511, and your local utility's outage page provide the information you need before a storm.
Which NWS office covers you?
Alaska's weather warnings come from three NWS offices:
Southeast Alaska: NWS Juneau
Southcentral and Southwest Alaska: NWS Anchorage
Interior and Northern Alaska: NWS Fairbanks
Search for your town on weather.gov and read the full warning text. It identifies the affected areas and expected conditions. Don't assume a warning is in effect without checking the latest update. Check your saved bookmarks, too. On March 18, 2025, NWS Anchorage replaced its 17 public forecast zones with 51 new zones. Names now include “Anchorage / Eagle River (lower elevations),” “Anchorage Hillside / Upper Eagle River,” “Lower Matanuska Valley,” “Thompson Pass,” and “Valdez.” An old zone name in an app or bookmark may no longer match. Anchorage's lower elevations and Hillside also have separate forecast wording.
Check road conditions on Alaska 511
Visit Alaska 511 or use its free iPhone and Android apps. My 511 lets you save routes and set notifications.
By phone: Dial 5-1-1 in Alaska or call (866) 282-7577 from out of state. The phone system reports events on major highways only.
Update timing: Winter road conditions are generally posted in the morning and updated in the early afternoon. Alerts can change as new information comes in.
Before driving: Check NWS forecasts as well as road reports. Never call 511 or text while driving.
Alaska 511 uses these ratings to describe winter travel conditions:
511 rating | What it means in winter |
Good | Roads are passable; mostly bare or cleared, sporadic icy patches or packed snow possible |
Fair | Passable with varying conditions; packed snow, icy patches, limited blowing and drifting snow |
Difficult | Challenging even for properly equipped vehicles; up to 3 inches of snow, ice, freezing rain, blowing snow |
Very Difficult | "Travel is not advised"; 4 inches or more, drifts, berms, low visibility in wind |
Hazardous | "Travel is not advised"; roads may be blocked or impassable; high winds may cause blizzard-like conditions |
Road Closure | Closed until safe travel can resume |
No Winter Maintenance | "Travel is not advised"; a few major highways aren't maintained in winter, with no emergency services or travel assistance |
For power outages, use your utility's outage page. The utility links are listed in Section 5. If a power line is down or there is immediate danger, call 911 and stay well away. A blizzard warning can change plans both inside and outside the house. Staying safe during a blizzard starts with deciding early whether to travel at all. Once you know which NWS office covers your area, check what its warning criteria mean. The snowfall needed for a Winter Storm Warning differs across Juneau, Anchorage, and Fairbanks.
Alaska Winter Storm Warning Criteria: Why the Snowfall Trigger Changes by Region
Alaska does not use one snowfall threshold for every winter storm warning. Each National Weather Service (NWS) office sets criteria for its forecast areas, so the amount of snow that triggers a warning in one region may be much higher than in another. These thresholds are guidance, not guarantees; forecasters may issue warnings when expected impacts justify them. The criteria below come from the NWS Alaska Region Supplement 07-2002, Alaska WFO Winter Weather and Non-Precipitation Weather Products Specification, dated April 26, 2019. Because Anchorage's forecast zones changed in March 2025, the table groups the criteria by office and area grouping rather than using the old zone numbers.
NWS office and area group | Winter Weather Advisory | Winter Storm Warning |
Juneau: Most Southeast zones | 4 to 5 inches in 12 hours; 3 to 5 inches in two zones | 6 inches in 12 hours or 12 inches in 24 hours |
Juneau: One zone | 8 to 11 inches in 12 hours | 12 inches in 24 hours |
Anchorage: Most zones, including the Anchorage Bowl area identified in the document | 6 to 11 inches in 12 hours or 12 to 23 inches in 24 hours | 12 inches in 12 hours or 24 inches in 24 hours |
Anchorage: Three higher threshold zones | 18 to 23 inches in 12 hours in one zone; no advisory threshold listed for the other two | 24 inches in 12 hours |
Fairbanks: First group in the document | No threshold listed | 6 inches in 24 hours |
Fairbanks: Group linked to Fairbanks airport (PAFA) | 4 to 7 inches in 24 hours or less | 8 inches in 24 hours or less |
Fairbanks: Third group in the document | 6 to 11 inches in 12 hours or less, or 12 to 23 inches in 24 hours or less | 12 inches in 12 hours or less, or 24 inches in 24 hours or less |
The 2019 document identifies the Fairbanks groups by zone numbers, not by current area names. Check the current NWS Fairbanks forecast zones before assigning geographic names to those groups.
Blizzard, ice, and extreme cold warnings
A Blizzard Warning requires visibility below one quarter mile from blowing snow, winds above 35 mph, and conditions lasting at least three hours. A blowing snow advisory uses a lower threshold: winds of 25 mph and visibility of one-half mile or less for at least three hours. Ice Storm Warning thresholds are 0.25 inches for Juneau and Anchorage and 0.10 inches for Fairbanks.
When to prepare for a storm
Winter storm watches are generally issued 24 to 48 hours before an event, giving you time to charge devices and prepare for outages. The NWS now uses Extreme Cold Warning and Cold Weather Advisory instead of the older wind chill alert names. Knowing how a blizzard differs from a snowstorm explains why strong winds and poor visibility can close roads even with little new snow. Use the watch period to decide which essential devices you'll need to keep running if the power goes out.
What to Power First Under an Alaska Blizzard Warning: EcoFlow DELTA 3 Classic and EcoFlow DELTA 3 Ultra Plus
When a blizzard knocks out power, focus first on staying connected and having enough light to move around safely. Keep phones, your Wi Fi router, a weather radio, and emergency lights running before turning to the refrigerator or other appliances. Check each device's power requirements and plan what you'll run before the storm arrives.
Keep the power station warm and dry
Important for Alaska residents: EcoFlow's US store ships to the contiguous United States and excludes Alaska. This section is intended for people who already own an EcoFlow DELTA 3 Classic or EcoFlow DELTA 3 Ultra Plus, or who have confirmed local availability, delivery, and after-sales support. Both models have a listed discharge range of 14°F to 113°F and a charging range of 32°F to 113°F. Keep the power station inside a heated living space, away from snow and rain. Don't leave it in an unheated garage, shed, or parked vehicle during subzero weather. If it has been sitting in the cold, let it warm up indoors before charging.
Follow this backup power order
Communications: Charge phones and power your router, modem, and weather radio, where compatible.
Lighting: Run rechargeable emergency lights and lamps so you can move around safely.
Food storage: Power the refrigerator first, then the freezer if capacity allows. According to FoodSafety.gov, a closed refrigerator keeps food cold for about four hours. A full freezer can hold its temperature for about 48 hours, or about 24 hours if half full.
Other appliances: Run compatible 120V appliances one at a time, checking their power requirements and the total load before connecting them.
Here is how the two power stations compare for these priorities. The right power station depends on which devices you need to run and for how long. Here's how the EcoFlow DELTA 3 Classic and EcoFlow DELTA 3 Ultra Plus compare in capacity and output.
For households that need more backup capacity, the EcoFlow DELTA 3 Ultra Plus offers a larger 3,072Wh battery, expandable capacity, and smart output controls to help prioritize essential devices during a longer outage.
Match the power station to your needs
The EcoFlow DELTA 3 Classic (1,024Wh, 1,800W) suits phones, routers, weather radios, and emergency lights. The EcoFlow DELTA 3 Ultra Plus (3,072Wh, 3,600W) offers more capacity for a refrigerator and other compatible 120V appliances. Keep the combined running load below 3,600W and allow for startup surges up to 7,200W. Neither unit supports 240V appliances, and X Boost does not increase rated output.
How long will the battery last?
These are estimates, not guaranteed runtimes. They assume 85% of the battery's rated energy is usable after conversion losses.
EcoFlow DELTA 3 Classic: Of its 1,024Wh capacity, about 870Wh may be usable. For example, with a combined load of 50W for your phone chargers, router, modem, and lights, that works out to roughly 17 hours.
EcoFlow DELTA 3 Ultra Plus: Of its 3,072Wh capacity, about 2,611Wh may be usable. A refrigerator using around 630kWh per year consumes roughly 1.7kWh daily, giving this unit about 1.5 days of runtime for the refrigerator alone.
Your actual runtime will depend on the devices and how often they run. Check your refrigerator's EnergyGuide label for annual energy use, divide that figure by 365, and use it to estimate daily consumption. Running other appliances will shorten the runtime, while compatible extra batteries can extend it.
Recharging during an extended outage
The EcoFlow DELTA 3 Classic recharges from 0 to 80% in about 45 minutes using AC power. The EcoFlow DELTA 3 Ultra Plus takes about 89 minutes at 1,800W AC input, or 48 minutes when solar and an EcoFlow Smart Generator charge it together. Alaska's limited winter daylight can reduce solar charging, so keep a backup plan. Run fuel-powered generators outdoors, at least 20 feet from doors, windows, and vents, never in a garage or carport.
Smart Output Priority controls the Ultra Plus's own outlets. Backing up home circuits requires a compatible transfer switch and inlet box installed by a licensed electrician. Never feed power into your home through a wall outlet. For your internet connection, this guide to battery backup for modems and routers can help you estimate the power you need. Power planning is one part of storm preparation. Alaska's recent storms also show why it's important to plan for road closures, extended outages, and evacuation orders.
Alaska Storm 2026: Record Snow, Roof Collapses, and the Evacuations Behind the Headlines
Searches for “Alaska storm 2026” cover several events, from record snowfall in Juneau and Anchorage to a coastal storm that forced hundreds of people to evacuate western Alaska. State and federal records document the damage, evacuations, and prolonged cold that affected communities during the 2025 to 2026 winter season.
The 2025 to 2026 Alaska storm season on record
Event | What the official record says |
Juneau, December 2025 | 82.0 inches of snow, a December record by 27.3 inches (records from 1943) |
2026 Jan Southeast Winter Storm (December 2025 to early January 2026) | "Record-breaking snowfall," collapsed roofs, heightened avalanche concern; the City and Borough of Juneau "issued an evacuation advisory and opened an emergency shelter"; state disaster declaration covering Juneau, Hoonah, Haines, Skagway, and the Chatham REAA (release dated January 10, 2026) |
Anchorage, January 2026 | 40.2 inches, a January record and the city's 5th snowiest month (records from 1954) |
Fairbanks, February 2026 | 39.9 inches, the 2nd snowiest February and 7th largest monthly total (records from 1905) |
Northwest Arctic Borough, March 2026 | Months of "sustained extreme cold" froze water and sewer systems in Selawik, Shungnak, Ambler, and Buckland; providers "struggled to maintain power"; disaster declared (release dated March 26, 2026) |
Alaska storm evacuations: The October 2025 West Coast storm
The October 2025 West Coast storm was different from Alaska's major snowstorms. Remnants of Typhoon Halong brought high winds and coastal surge, damaging western Alaska communities and disrupting essential services.
October 13, 2025: Forty-nine communities were reporting impacts from high winds and coastal surge. Kwigillingok reported a power outage.
October 17, 2025: Three airlift evacuations from Bethel to Anchorage had moved 573 people that week.
October 22, 2025: FEMA declared a major disaster for the Lower Kuskokwim REAA, Lower Yukon REAA, and Northwest Arctic Borough. The incident period ran from October 8 to 13.
April 22, 2026: The state reported that 165 households, representing 681 people from Kipnuk, Kwigillingok, and other parts of western Alaska, had moved from Anchorage hotels into temporary housing.
Keep your phone and power bank charged during storm warnings. Follow evacuation instructions and bring essential medications and chargers. If evacuating by air, ask officials which devices you can bring. The October 2025 typhoon remnants left communities without power, water, and communications. Whatever the threat, contact your utility directly for outage updates, as reporting systems vary across Alaska.
Alaska Power Outages During a Winter Storm: Chugach, MEA, GVEA, AEL&P, and HEA
Alaska's electric utilities serve different regions, so there's no single outage page for the whole state. Save the correct utility contact before a storm and follow your utility's specific reporting guidelines if you experience an outage.
Utility | Outage page and map | How it says to report |
Chugach Electric Association | chugachelectric.com/outages; map at chugachelectric.com/outage/outage_map.html (Chugach notes "there can be a delay in real-time updates") | "Anchorage" 907-762-7888; "Outside Anchorage" 800-478-7494; online e-form |
Matanuska Electric Association (Mat-Su and Eagle River) | mea.coop/power-outages | MEA Power Outages Page (call 907-745-3231 or 800-478-3551 to report an outage) |
Golden Valley Electric Association (Interior) | "24-Hour Outage / Emergency Phone" (907) 452-1151 | |
Alaska Electric Light & Power (Juneau) | aelp.com Outage Updates page | Outage hotline 907.586.2357; text OUTAGE to 55050 from the cell phone associated with your AEL&P account |
Homer Electric Association (Kenai Peninsula) | homerelectric.com Outage Reporting; map at outage.homerelectric.com (also in HEA's mobile app) | (888) 868-8243; HEA says not to report on Facebook or Messenger because "Dispatch does not receive these alerts" |
Check your utility's official website for current outage information and reporting instructions. Stay away from downed power lines and report them to the utility or emergency services. If a line falls on your vehicle, remain inside and call 911 unless staying inside puts you in immediate danger. AEL&P also warned during a December 2025 storm that falling snow from trees could cause additional outages. If the power stays off, use this guide to how long food stays safe in the fridge without power to help prioritize backup power for refrigeration.
GVEA energy emergency alerts: When power supply is limited
Not every outage is caused by snow or damaged lines. Golden Valley Electric Association (GVEA) issues Energy Emergency Alerts when available electricity is limited.
Level 1: Conserve electricity where practical.
Level 2: Conserve immediately and prepare for possible outages.
Level 3: Prepare for rotating outages, which may last approximately 30 to 60 minutes. Advance notice is not always possible.
Alert levels can change, so Interior residents should check GVEA's official alert page for the current status. During a short rotating outage, a portable power station with a 10-millisecond automatic switchover, such as the EcoFlow DELTA 3 Classic, can help keep compatible devices connected when plugged directly into the unit. This can be useful for a router and phones, but check their power requirements and the station's runtime before relying on it.
Conclusion
A snowstorm warning in Alaska can mean different snowfall amounts in Juneau, Anchorage, and Fairbanks. Check the NWS office for your area, use Alaska 511 before driving, and keep your utility's outage page saved. When a watch arrives, charge phones and lights, review appliance wattage, and keep backup equipment indoors and dry. If you already own an EcoFlow DELTA 3 Classic or EcoFlow DELTA 3 Ultra Plus, test it with your priority devices before the next storm. If you're considering buying one, confirm Alaska availability and support first.
