Points saillants

Today the avalanche danger will rise to CONSIDERABLE on east, south and west facing terrain as the snow becomes wet. Wet avalanches should happen naturally. Most should be wet loose avalanches but shallow wet slabs are possible. The danger will rise to MODERATE even on north facing slopes if the snow becomes wet. Go to upper elevation north facing terrain where the snow remains dry; however, be watching for any terrain above where the snow may heat up quicker than you realize. Exposed rocks readily absorb sunshine and quickly heat up the snow around them.

Today's warm temperatures and strong sunshine will be a big change to layers of new snow from last weekend (6-12 inches) and from Thursday (up to 4 inches). This past week has had periods of sunshine and warm temperatures but no sustained warm, sunny weather like today.

The upper foot of snow should quickly become wet today starting with east facing slopes that receive the first sunshine and then quickly going to south and then west facing slopes. Even the snow on north facing slopes at low elevations and some mid elevations should become wet as the day heats up.

Honestly, I'm a bit uncertain exactly how the snow will react. As the snow becomes wet, there should be wet loose avalanches. However, what's causing me concern is yesterday's wet slab avalanche reported on Elk Point on Mt. Timpanogos. There could be more like it or there could be none, it's just hard to say.

Look for clues that the likelihood of wet avalanches is increasing. As the snow gets wetter and you see more and more pinwheels and rollerballs tumbling downhill, the likelihood of wet avalanches is increasing.

Recent Activity

There was a wet slab avalanche that happened yesterday at Elk Point on Mt Timpanogos. It was 6 inches deep and about 200 feet wide. Wet slabs are very hard to predict, but when one happens it should make us pay attention because others may happen.

Snow and Weather

Yesterday skies were mostly cloudy in the morning but dissipated in the afternoon and some sunshine appeared. This morning temperatures are mostly in low 20s F, and winds are blowing 10 mph gusting to 20 mph at most ridgelines from the northwest and west.

Today will be warm and sunny with light winds. Temperatures will quickly climb into the low 40s F. Winds will blow from the north and ease blowing only about 5-10 mph.

Looking ahead, Sunday will be similar to today but warmer. A cold front will cross northern Utah on Monday and bring much colder temperatures. Unfortunately there won't be much moisture in this system.
