Thank you to everyone who supported our spring fundraiser. We reached our goals. The Utah Avalanche Center could not exist without your support.
The Tony Grove Snotel at 8400' reports 83 inches of total snow, and it's 46ºF this morning. Its 42ºF at the 9700' CSI Logan Peak weather station, and south winds are currently averaging around 25 mph.
Rapid warming and mountaintop temperatures well above 50ºF will again create dangerous wet avalanche conditions on steep sunny slopes in the Logan Zone.
A mild southwesterly flow will keep above average temperatures in place through today. A mild storm system will cross the state late tonight through Monday, followed by high pressure for the middle of next week.
It will be partly sunny today in the mountains again, with high temperatures at 9000' expected to be around 54ºF and 8 to 14 mph south-southwest wind. Scattered rain and snow showers are possible this afternoon, and some thunder is also possible. Rain and snow showers are likely tonight, and thunder is possible. It will be mostly cloudy with low temperatures around 34ºF, and 11 to 16 mph southwest winds. Rain and snow showers will change over to all snow tomorrow afternoon, with a chance of thunder but little accumulation expected. Expect high temperatures around 43ºF and 5 to 15 mph north-northwest wind, veering from the west in the afternoon.
Here is a short video from Utah Avalanche Center Staff about Spring snow.
We can see numerous recent natural wet loose avalanches from Cache Valley today after the rainy and increasingly warm weather this week. Widespread natural loose avalanches entraining wet new snow were observed across the Logan Zone on many steep slopes at upper and mid elevations, and some were pretty long running. Skiers report triggering sizable wet loose avalanches on the north side of Logan Peak on Thursday and in Bird Canyon in the Wellsville Mountain Wilderness yesterday.
A skier triggered wet loose avalanche in Bird Canyon occurred at around 10:30 yesterday morning.
Natural wet avalanches from cornice falls occurred during the heat of the day yesterday in the backcountry cirques above Snowbasin.
The heat is causing large ridge top cornices to buckle and sag, and large pieces to calve off creating wet avalanches on slopes below.
Numerous fairly large natural wet loose and a few wet slab avalanches occurred in the first half of April across the Logan Zone.
