Logan Avalanche Advisory

Forecaster: Toby Weed

BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

There is a LOW danger in the backcountry, but you still might trigger shallow wet avalanches on a few very steep slopes. Warming will likely cause a higher danger at times during this spring's melt, especially when nighttime temperatures do not fall below freezing for a while. Its generally best to get an early start and be done early in the springtime.

You should watch for unstable snow on very steep isolated slopes, especially during warm spells this spring....


CURRENT CONDITIONS

Trailheads offering onto-the-snow access are becoming more rare, with Beaver Creek the best option for riders these days. Remember to avoid snowmobile travel over melted-out ground, as this causes resource damage and may lead to additional regulations or early closures. The Tony Grove Snotel reports 80 inches of total snow still on the ground at 8400' containing 107% of average water for the date.


RECENT ACTIVITY

No avalanches reported or observed in the Logan Area since the exceptionally warm weather last week. (4-23-09 Photos) .... (4-30-09 PHOTOS)


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Low danger but wet avalanches are still possible on isolated slopes steeper than about 40 degrees...Expect the danger to rise with temperatures this spring. Significant spring snowstorms, which aren't all that uncommon around here may cause a danger of new snow avalanches. Fresh snow is quite succeptable to rapid warming this time of year, and moist avalanches are likely soon after any significant accumulation....


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

The danger of wet avalanches will continue to be a threat this spring, especially when temperatures rise again and it stays above freezing for a few nights...


MOUNTAIN WEATHER

Looks like nice cool springlike, unsettled weather will continue into the next week, with periods of snowfall likely at upper elevations.....
