September 8, 2026

A quiet weather morning across most of the region, with the active items in Alaska and a frost advisory in Oregon.

The National Weather Service active alert feed, read at 1:01 this morning Eastern time, counts nine active land alerts in Alaska and one in Oregon. Idaho and Washington show none.

In Alaska, the set includes two wind advisories, two high wind watches, four high surf advisories, and a special weather statement. The wind advisory for the Municipality of Skagway runs from 1:00 this afternoon to 1:00 tomorrow morning Alaska time, with south winds of 25 to 35 miles an hour and gusts to 50, strong enough to move unsecured objects and bring down limbs with scattered outages possible. A high surf advisory for the southern Seward Peninsula coast begins at 4:00 tomorrow morning and runs to 4:00 Friday afternoon Alaska time, with water levels 3 to 4 feet above the normal high tide line at each high tide and localized beach erosion expected.

In Oregon, a frost advisory covers valleys and basins in Lake and Klamath counties, and in California's Modoc County, with widespread frost and local areas as low as 31 degrees. Communities named include Crescent, Chemult, and Fort Rock. That is the first frost product of the season in this brief and it is a normal date for it at that elevation. The practical items are covering tender plants and, for anyone with an outdoor water line or an RV, remembering that 31 degrees is enough to matter.

The Storm Prediction Center places no severe thunderstorm risk in the region, and the Weather Prediction Center carries no excessive rainfall risk area here through tomorrow morning.

Wildfire is the dominant infrastructure story in this region and the numbers are large.

In Washington, thirteen large fires are burning on the National Interagency Fire Center's current incident list. Little Giant stands at 171,163 acres and 81 percent contained, Sinlahekin at 166,116 acres and 59 percent, Ptarmigan at 25,166 acres and 73 percent, Three Queens at 9,444 acres and 11 percent, Border 2 at 8,043 acres and 73 percent, Luna at 7,722 acres and 34 percent, King at 3,146 acres and zero percent, High Lava at 2,899 acres and 63 percent, Sisi at 2,521 acres and 11 percent, Thunder Creek at 950 acres and zero percent, Goat at 809 acres and 3 percent, Electric at 622 acres and 24 percent, and Wonderland Complex at 387 acres and 11 percent.

In Oregon, nine large fires. Big Grass stands at 578,637 acres and 94 percent contained, Rowe Creek Complex at 373,927 acres and 99 percent, Grasshopper at 93,990 acres and 91 percent, Hagen at 61,396 acres and 56 percent, Wrights Spring at 55,134 acres and 95 percent, McCully at 13,565 acres and 46 percent, Austin at 12,610 acres and 19 percent, Paradise at 9,646 acres and 28 percent, and The Narrows at 302 acres and 27 percent.

In Idaho, twelve large fires, most of them modest in size but several with no perimeter secured. Crooked stands at 10,118 acres and 60 percent, Cascade at 7,475 acres and 50 percent, Moose Mountain at 5,832 acres and fully contained, Upper Smith at 4,848 acres and 41 percent, Grotto at 3,849 acres and zero percent, Silver at 2,593 acres and 20 percent, Wolf Creek at 2,280 acres and 25 percent, Doublesprings at 1,779 acres and 50 percent, Parker Lake at 1,531 acres and zero percent, Dudley at 800 acres and 88 percent, Three Links at 790 acres and zero percent, and Porcupine at 180 acres and zero percent.

Containment measures how much of the fire's edge is secured, not how much of the fire is out. The fires worth watching are the low containment ones near people: Austin in Oregon at 19 percent, Paradise at 28 percent, and McCully at 46 percent, along with Three Queens, Sisi, and Goat in Washington in the low double digits and single digits.

The national wildfire preparedness level is 4 on a five step scale, set September 4 at 7:30 in the morning Mountain time, according to the National Interagency Fire Center. Its national fire news page, current September 7, counts 65 large fires with 15,855 firefighters and support staff assigned, and 53,233 fires for 8,303,398 acres so far this year.

Alaska carries a fire management assistance grant, number 5672, for the Mukluk fire, issued August 18. No new federal disaster declarations for Idaho, Oregon, or Washington appear in the Federal Emergency Management Agency's record since the middle of August.

No air quality alerts are active in the four states, which given the fire count depends entirely on wind direction rather than on the fires easing.

Specific air quality index readings near the Washington, Oregon, and Idaho fires were not obtained this run. The Fire and Smoke Map at fire.airnow.gov gives a current local number for any address, and it is the tool worth bookmarking if you live within a day's smoke drift of an open perimeter.

The practical smoke guidance does not change: when the air is bad, keep windows closed, run a filter if you have one, and postpone hard outdoor exercise. A box fan with a furnace filter taped to it is the low cost version of an air cleaner and it works well enough in one room.

No boil water advisories were identified across the region.

The Centers for Disease Control and Prevention Health Alert Network archive could not be read this run, so this brief makes no claim about national health advisories in either direction.

Two items, one seismic and one seasonal.

The seismic one is settled rather than developing. A magnitude 5.3 earthquake occurred off the coast of Oregon at 1:30 in the morning Universal time on Sunday, according to the United States Geological Survey event feed queried at 5:09 this morning Eastern time. It produced a tsunami information statement rather than a warning, and the National Tsunami Warning Center's page states that no tsunami warning, advisory, watch, or threat is in effect for the United States or Canada.

An information statement is the lowest tier of tsunami message. It means an earthquake occurred and a tsunami is not expected, and it exists so that people who felt the shaking or heard about it have an authoritative answer. Nothing about it calls for action.

The Aleutian sequence near Nikolski, Alaska has quieted. It peaked at magnitude 6.3 on September 3 and produced more than twenty events of magnitude 4 or greater over three days. The most recent event of that size was a magnitude 4.9 on September 5. Nothing of magnitude 4 or larger has occurred in that area in the past two days. That is the ordinary way an aftershock sequence ends.

The seasonal item is the pattern change, and this region sees it first. The Weather Prediction Center's extended discussion, issued at 1:41 yesterday afternoon Eastern time, has upper level troughing strengthening into the Northwest late this week and reinforcing next weekend, with a cold front pushing south across the region and bringing unsettled weather. Model agreement on the timing is poor, which the center says directly, so the useful reading is that rain is coming to the Northwest late this week rather than that it arrives on a particular day.

For fire crews, a wetting rain across Washington, Oregon, and Idaho would do more for containment than anything else available. For households, the first substantial rain after a long fire season brings its own item: burned ground does not absorb water, so slopes that burned this summer can produce debris flows in a heavy rain that would have been unremarkable a year ago. If you live below a burn scar, the rain that helps the fire is the rain to watch.

For Alaska, the autumn storm season is opening, and the high surf and wind products this week are its first ordinary examples.
