Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for April 19, 2014 - 6:40am
bottom line

Overnight temperatures stayed in the mid to upper thirties, and the snow surface is only superficially refrozen. Heightened wet avalanche conditions exist, and a MODERATE or level 2 danger could develop in some steep terrain by afternoon. Wet avalanches are possible. Evaluate the snow and terrain carefully.

danger scale: Low Moderate Considerable High Extreme
current conditions

A poor freeze overnight means only a superficial refreeze of the surface snow, and warm temperatures today will soften things up fairly rapidly. It's 35 degrees up at the 8400' Tony Grove Lake Snotel, and there's 88 inches of total snow containing 137% of average water for the date. I'm reading 34 degrees at the 9700' CSI Logan Peak weather station, with southwest winds averaging around 12 mph.

description

Good general rule to avoid travel in the heat of midday. It's always a good idea to get an early start and leave the mountains before the saturated snow turns to mush.

Avoid and stay out from under large and overhanging cornices along major ridge-lines, which are likely to break further back than you expect and could trigger avalanches on slopes below.
