Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Wednesday - April 6, 2016 - 6:56am
bottom line

LOW (Level 1): Freezing overnight temperatures and westerly winds should keep the saturated snow fairly solid today in the backcountry. Heightened wet avalanche conditions may develop in some steep sheltered terrain as the surface snow warms and softens up again with daytime seasonal and solar warming. Use normal caution and retreat from steep slopes if you start sinking into melt-softened wet snow.
current conditions

The Tony Grove Snotel at 8400' reports 30 degrees this morning and 87 inches of total snow containing 101% of average water for the date. Temperatures dropped below freezing again overnight and I'm reading 22 degrees at the 9700' CSI Logan Peak weather station, with west winds currently averaging around 25 mph. Looks like a decent refreeze of the wet snow surface at least at upper elevations. You might find areas with nice supportable and softening spring snow on sunny upper elevation slopes, but be willing to turn around if the wet snow you are in gets soft and sloppy.
recent activity

Natural wet avalanches during the heat of the day and involving late March snow were common across the Logan Zone in the first few days of April.

These long natural wet avalanches in the Wellsville Mountain Wilderness occurred during the weekend warm spell or on Monday (4-4-16)

Moist sluffs entraining melt-saturated surface snow are possible with warming daytime temperatures again today, most possible on sunny sheltered slopes where saturated surface snow becomes softened by solar warming. You should leave a steep slope if you start sinking into melt-softened wet snow.

You'll find stable snow conditions after mountain temperatures dipped below freezing overnight, solidifying the wet snow. Your biggest threat today could be falls or "slide for life" slides in steep terrain on hard refrozen snow.
