Advisory: Logan Area Mountains | Issued by Toby Weed for Wednesday - December 27, 2017 - 6:50am |
---|
current conditions Lots of heavy snow and drifting from strong west winds overloaded widespread weak sugary snow, and dangerous avalanche conditions exist in the backcountry. The Tony Grove Snotel at 8400' reports 27°F and 47 inches of total snow containing 109% of normal SWE (Snow Water Equivalent). The site recorded around 25" with 3.9" SWE between Friday, 12/22/17 and Christmas Night. It's 18°F at the 9700' CSI Logan Peak weather station, and the wind sensor is still not reading due to ice. It is still pretty windy at the UDOT Hwy 89 summit weather station with 15 mph west wind and gusts of close to 30 mph

description
Along with the gift of powder snow, Santa also brought a slab made up of stronger snow that now sits precariously upon widespread weak sugary snow formed during the prolonged December high pressure system. Persistent slab avalanches are likely even in sheltered areas.
Cracking like this and collapsing are sure signs of persistent instability. |
weather High pressure aloft along the west coast will maintain a dry and mild west-northwest flow across much of Utah over the next several days.
