Logan

Another night of no overnight refreeze and forecast warm daytime temperatures have created heightened avalanche conditions. There is a MODERATE danger and human-triggered and natural wet avalanches are possible in steep and/or sunny terrain. While unlikely, there is a potential for dangerous avalanches to be triggered in upper and mid-elevation terrain, where a persistent weak layer is buried 3 to 4 feet deep.

Evaluate the snow and terrain carefully, and continue to practice safe travel protocols.

No avalanches were reported yesterday.

Expect yet another beautiful day in the mountains with sunshine and warm temperatures. It has been 72 hours since the thermometer dipped below 32° F at Tony Grove. This means, once again, the snowpack did not refreeze thoroughly, though radiational cooling may have helped a bit with last night's clear skies. We'll start the day with less stability again, and wet avalanches may occur earlier in the day. If you are sinking deeply into the mashed potato snow, move to a cooler aspect or elevation or simply move away from steep terrain. With a temperature inversion this morning, I'd expect the snow to be somewhat unsupportable on upper and mid-elevation slopes that stayed warm overnight and more supportable in low-elevation terrain where temperatures got slightly below freezing. If you venture into higher elevations, avoid traveling on or beneath overhanging cornices, as they are weakening due to the warm temperatures.

The Tony Grove Snotel at 8400 feet reports 38° F, with 88 inches of total snow. The high at Tony Grove yesterday was 54° F. It's 39° F at the Card Canyon weather station at 8800 feet, with 62 inches of total snow.

At 9700 feet at CSI's Logan Peak Wx station, winds are blowing 10-15 mph from the south-southwest and it's 36° F. On Paris Peak at 9500 feet, it's 36° F, with winds blowing 8 to 13 mph from the south-southwest.

Today's mild southerly flow will overspread the Logan zone, boosting max temps 15°F or so above average. Expect very warm conditions in the mountains with an 8500' high of 50°F or more and light winds. It should be sunny for most of the day, but clouds may build in this afternoon ahead of an incoming storm system. The National Weather Service has issued a Winter Weather Advisory beginning Monday at 5 am and lasting through Tuesday at 11 am. The mountains could pick up 3-7" by Tuesday morning. Unsettled weather continues until Friday.
