    Alaska Storm Alerts

    Active National Weather Service hail, wind, thunderstorm, tornado, tropical and winter storm alerts covering Alaska, with the counties each one names and the office that issued it — plus what the state’s severe-weather season looks like and how each of these events actually damages a roof.

    Below that, in its own lane, the smoke and fire family: fire weather, dense smoke, air quality, blowing dust and volcanic ashfall.

    Special Weather Statement issued August 25 at 1:10PM AKDT by NWS Fairbanks AK

    NWS description

    Areas of rain on Tuesday will transition to snow in the Eastern Brooks Range Tuesday evening. Snow then continues through the day on Wednesday. Given the rain beforehand, snow will struggle to accumulate immediately but there will be minor accumulations by Wednesday morning. Wednesday afternoon there may be a brief break, allowing snow to gradually melt. Then snow returns Wednesday evening before diminishing into snow showers Thursday morning. Snow totals around 1 to 2 inches are expected overnight Tuesday into Wednesday in the area from Atigun Pass to Sagwon. Snow will continue through the day but struggle to stick due to warmer temperatures and higher sun angle. Wednesday night, another 1 to 2 inches of snow are expected to accumulate before tapering off.

    NWS radar — Alaska

    National Weather Service radar for Alaska, covering the Alaska radar network.

    Where precipitation is falling over Alaska right now. The National Weather Service publishes these mosaics by region rather than by state, so the frame runs past the state line and neighbouring states are visible in it. Radar shows precipitation, not damage — a return over a county is not evidence that any particular building was hit.

    Radar imagery: the National Weather Service. Served directly from radar.weather.gov, a free US Government service, and regenerated by NOAA roughly every two minutes — your browser picks up new frames on its own. This site does not process, re-colour or re-time the imagery; it is the Weather Service’s own mosaic, unmodified. weather.gov

    Smoke & fire lane

    Smoke & fire alerts in Alaska

    The National Weather Service issues a separate family of alerts for fire weather, dense smoke, air quality, blowing dust and volcanic ashfall. This lane reports that family for Alaska, kept apart from the storm alerts above because the two answer different questions.

    Wildfire smoke is what drives smoke-damage losses, and it reaches a building through the same vents that keep an attic dry — which is why it belongs on a roofing page at all. Alerts describing particulate already in the air are listed ahead of fire-weather forecasts; that ordering is this lane’s own and is not a Weather Service ranking.

    No active smoke or fire alerts

    The National Weather Service has no active fire weather, dense smoke, air quality, blowing dust or volcanic ashfall alerts covering Alaska as of this refresh.

    An empty list here is the ordinary reading, not a fault and not a gap in the data. Most of the country carries nothing in this family on most days, and this lane fills itself the moment the Weather Service issues something.

    The 12 alert types this lane reports

    Every one is a National Weather Service product and is listed under the name the Weather Service gives it. Grouping them into families is ours; the names are not.

    The Weather Service defines each of these products and this site does not attempt to. What any one of them means, and the criteria an office issues it under, are at weather.gov.

    This lane is informational and is not a safety resource. It reports which National Weather Service smoke and fire alerts are active and where, on a ten-minute refresh cycle, so it can lag the Weather Service.

    During an active weather event, the authority is weather.gov and your local emergency management agency. Follow them, not this page.

    Smoke exposure and air quality are health matters, and this page does not address them. It does not tell you whether it is safe to be outdoors or to work, what an air quality index number means for you or for anyone in your household, or what respiratory protection to use. Those questions belong with a clinician and with the agency that issued the alert. The federal air-quality authority is airnow.gov.

    What smoke does to a roof assembly

    An active alert is a record of conditions, not a finding about any building. These are the standing references on the building-assembly side of a smoke or fire loss.

    Severe weather season in Alaska

    Peak season

    October–March

    Alaska’s roof-damaging weather is a winter story. Strong extratropical storms moving out of the Gulf of Alaska and the Bering Sea drive high winds along the coast, and snow loading is the dominant structural concern almost everywhere else. Severe thunderstorms and hail are uncommon, so the National Weather Service products that matter most here are wind, winter storm and blizzard warnings rather than convective ones.

    Seasons describe a pattern, not a schedule. The National Weather Service issues these products year-round, and the live list above is the only authority on what is actually running in Alaska right now.

    What NOAA has recorded in Alaska

    The archived record, not the live feed. Severe weather logged by the National Centers for Environmental Information over the covered years, split into the events NOAA keys to a county and the events it keys to a forecast zone.

    Between 2016 and 2026, NOAA recorded 14 county-level severe-weather events across Alaska: 7 thunderstorm wind events, 5 hail reports, 1 heavy snow event and 1 tornado. Of the five hail reports carrying a measured size, five were 1.00 in across or larger.

    A further 2,083 events over the same period were recorded against National Weather Service forecast zones rather than counties — 686 high wind events, 535 blizzards, 447 heavy snow events, 393 winter storms and 17 ice storms. A forecast zone is not a county: it can span several or subdivide one, so these are reported here at state level and appear in no county total on this site.

    County figures and state figures. County figures count events NOAA recorded against a county (hail, thunderstorm wind and tornadoes). High wind, winter storms, ice storms, blizzards, heavy snow, hurricanes and tropical storms are recorded against National Weather Service forecast zones rather than counties, so they are reported at state level instead. Counts reflect events that were observed and reported. NOAA does occasionally record one of those against a county instead. Where it has, the event sits in the county-keyed total above rather than the zone-keyed one — in Alaska that applies to heavy snow events.

    Source. Archived figures come from the NOAA National Centers for Environmental Information Storm Events Database, covering 2016 through May 31, 2026. Reports after that date come from NOAA Storm Prediction Center preliminary storm reports. Both are US Government works in the public domain. This is a record of past weather; the live alert list at the top of this page is the only authority on what is running in Alaska now.

    What these storms do to a roof

    The damage mechanisms that matter in Alaska, in the order they generate work here.

    Straight-line wind

    Wind damage on a shingle roof usually starts as a broken seal rather than a missing shingle. Uplift pressure is highest at the edges — rakes, eaves, ridges and hips — and along any line where the roof plane changes, so that is where tabs lift and the factory sealant strip lets go first. Once the seal is broken, a shingle that still looks fine from the ground is no longer bonded to the course below it and every later wind event works on the same spot. Wind also drives debris, and impact damage from a branch or from another roof’s material is a separate mechanism from uplift.

    Snow load and winter storms

    Winter loads a roof rather than striking it. Accumulated snow is a sustained weight on the structure, and drifting means the load is rarely spread evenly — it piles against ridges, dormers, valleys and the low side of any change in roof height. Melt-and-refreeze adds the second mechanism: heat escaping through the roof melts snow that then refreezes at the cold eave, and the resulting ice can back water up under the covering, which sheds water flowing downhill but not water standing still.

    Why the storm date matters

    Property insurance works from a date of loss — a specific storm on a specific day over a specific area, not a general observation that a roof looks worn. That is why the county list and the effective and expiry times on each alert above are the useful part of this page: they are the National Weather Service’s own record that a given event covered a given county at a given time.

    It also matters because hail damage is frequently latent. A fractured shingle mat can take a long time to become a leak, so the gap between the storm and the discovery can be considerable — and by then, establishing which storm did it is a records question rather than an observation. An alert naming a county is not evidence that any particular building was damaged; it is evidence of what the weather was doing over that county, which is where an assessment starts rather than where it ends.

    Source: the National Weather Service. Every alert on this page comes from the NWS public alerts feed at api.weather.gov, a free US Government service, and is reproduced as the issuing office wrote it. The office that issued each alert is named on the alert itself.

    This site does not edit, summarise or re-grade Weather Service text. Alerts are filtered into two separate lists — the event types that affect roofs, and the smoke, fire and airborne-particulate family — and each list is sorted. Nothing else is changed, and no alert is moved between the two lists to suit a heading.
