Mt. Baker Backcountry

NWAC has gone off their regular bulletin cycle for the West Slopes North zone, so there's no professional avalanche rating in play. That doesn't mean the hazard is zero — it means you're on your own to read the snowpack. The bulletin language says to watch for recent avalanches, cracking, and collapsing, which is the standard 'eyes open' guidance for shoulder season. With highs hitting 59°F Friday and 57°F Saturday and no overnight refreeze below the mid-40s, the real threat is wet loose on sun-exposed aspects once solar radiation gets into the snowpack. On steep south and southwest faces, that window closes fast — figure 10–11 AM depending on aspect and elevation. Plan your steep terrain for the morning hours and be out of the shot by late morning.

The snowpack data is a patchwork. Long Lake at 840 ft still shows 61 inches and 26.4 inches SWE with a falling trend — that's melt, not settlement, at that elevation. Annie Springs at 6,021 ft shows zero depth, meaning the snowpack at upper Baker elevations is patchy or gone at that station's specific location. At 31 inches reported for the Baker area, you're working with a late-season consolidated pack that's likely isothermal or close to it at lower elevations. Isothermal snow means no hard supportable crust in the morning — wet and heavy from the start on low-angle terrain, and prone to point releases on anything steep and sunny.

Weather window is workable Friday and Saturday — mostly sunny, winds light at 2–12 mph SSW, no meaningful precipitation. Sunday changes things: 30% chance of light rain by afternoon climbing to 71% Sunday night. Rain on the remaining snowpack accelerates wet avalanche cycles and degrades skiing fast. If you're on a three-night trip, plan your biggest objectives for Friday and Saturday morning, and either exit Sunday before the rain arrives or keep Sunday to low-angle mellow terrain. The SW wind component through the weekend is light enough that wind slab loading isn't a concern.

Stream crossings are non-issues — gauges are at normal to near-normal flows. With 15.5 hours of daylight and sunrise at 5:17 AM, you have a massive early window. Use it. Start moving by 6–7 AM to get steep aspects done before the snow softens, and you'll have a great two days before the Sunday rain ends the party.
