Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Drew Hardesty for Sunday - April 3, 2016 - 6:13am
bottom line

A LOW avalanche danger will rise to MODERATE and then CONSIDERABLE with daytime heating. The rapid rise of avalanche danger will start on the east, then south, then westerly facing aspects...with all but high north getting into the game by midday. Early starts and early exits are key this time of year. You're asking for trouble if you are in or below the steepest sunlit aspects after the snow has become unsupportable. Cornices may calve with the heating today.
current conditions

Skies are clear. Winds remain generally light from the west. Overnight lows as of 4am are in the upper 30s to low 40s, but I imagine a few more hours under clear skies should help help these elevations trend toward at least a superficial refreeze. Upper elevation northerlies hold cold, if variable, conditions.

recent activity

Wet loose naturalling continued like clockwork yesterday with a few observations coming in across the range. (Pic: Jake Hutchinson) Also, of interest, I was able to look at the GoPro footage of the incident on Monte Cristo from Friday and the debris looked less like wet loose snow and more like bits of fallen cornice.

description

The greatest concern for today continues to be heat-related activity. Despite a decent refreeze due to clear skies, overnight lows are in the "marginal" range and and the snow will soften and become unsupportable and unstable earlier today. When you start to see pinwheels, small natural wet slides, or you start to gouge in the wet slop with your skis or machine, it's time to head to a cooler aspect and low angle terrain. As the cold early week storm snow transitions with the heating, the sluffs may pry out a few wet slab avalanches as well.

I consider these conditions to be a time and place thing. If you're in steep sun-drenched terrain in the mid-afternoon, it's likely you'll be moving wet snow down the hillside. Remember that while wet sluffs move more slowly than dry avalanches, you'll want to avoid getting tripped up in the slow moving concrete, especially in confined terrain.

Note: Pay attention for wet activity in mid to low elevation north aspects, particularly during the afternoon hours.

weather

We'll have clear skies, light westerly wind, and daytime highs at 10,000' and 8000' in the upper 30s and mid 50s, respectively. May see a few clouds in the afternoon with a weak storm Monday night into Tuesday that'll bring cooler temps and perhaps a trace to an inch. High pressure rebounds for mid-week with unsettled weather moving in Friday into the weekend.
