Natural and human triggered wet loose and some wet slab avalanches can be expected today and your window for safe travel on supportable crusts will be earlier and more narrow than the last couple of days.
A couple things of note:
- Wet loose avalanches on nearly all aspects and elevations. Mountain temperatures will be warmer than yesterday, with daytime highs at 10,000' likely reaching into the mid-40s. Some upper elevation (above 9500') north facing slopes may be susceptible to wet loose avalanches.
- Wet slab avalanches. Some areas have not had a proper deep freeze for a couple of nights and free water pooling at various structural interfaces tends to promote wet slab releases. These wet slabs may be more likely on easterly or westerly facing aspects at the low and especially mid-elevations and be 1-4' deep and perhaps 1-200'+ wide. Wet slabs are generally much more dangerous and destructive than wet loose.
- Cornices are becoming weak and tender and are big enough to trigger large avalanches below, particularly on slopes that have avalanched previously this season. These are generally mid and upper elevation northwest to east facing slopes.
- Glide avalanches can be expected in the usual terrain of Stairs, Broads, and Mill B South of BCC and upper Porter Fork of MCC. I would absolutely avoid this terrain for the next few days (even after the cooler weather arrives).
- Roofs are shedding their winter loads. Please keep an eye on people, kids, animals underneath the roof lines.
