Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Bruce Tremper for Monday - March 2, 2015 - 7:09am
bottom line

The danger today depends how fast the storm piles up weight on the pre-existing soft snow. The danger should start at LOW this morning and rise to MODERATE by afternoon as the snow accumulates. As you travel, be sure to test how well the new snow bonds to the underlying snow by jumping on small test slopes and digging down with your hand. The danger may rise to CONSIDERABLE by Tuesday depending on what the storm does.

current conditions

It's starting to snow this morning as a pulse of moisture arrives from the south. So far, ridge top winds are light. Temperatures are 20 degrees at 9,500'. I'm expecting about 4-8 inches of snow today with snow continuing tonight and into Tuesday. Storm totals could be as much as 2 feet. Which is good because we certainly need the snow:

So how bad is our snow drought? HERE is my blog on the current stats.

recent activity

Not much significant activity yesterday with the exception of a small, skier-triggered sluff on a steep slope on the south face of Superior in the morning. The skier was caught in his own sluff and was carried about 200' before he got out of the sluff before it continued. He lost some poles and broke a ski but was otherwise OK.

Avalanche Problem 1
type aspect/elevation characteristics
over the next 24 hours

The storm beginning this morning has the potential to cause the first significant avalanche problems in about a month and a half. The day will start out at Low danger but as the load accumulates the danger should rise through the day, overnight and especially by Tuesday, we could see some significant activity. The new snow will likely slide on the pre-existing, low density layer of snow that fell over the past 3 days and has the potential to step down to deeper weak layers.

As always during a storm, you should continually test how well the new snow bonds to the old snow surfaces by jumping on small, test slopes and digging down with your hand. The avalanche danger through this storm will depend directly on what we call the "precipitation intensity", meaning how fast the storm adds weight as it accumulates. If it starts snowing fast and furious, expect the avalanche danger to spike especially in steep terrain.


Snow is just starting this morning and should continue today, tonight and on Tuesday. I'm expecting 4-8 inches of new snow today and storm totals may reach as much as 2 feet by later on Tuesday. The storm is coming up through southern Utah and has already added over an inch of water weight to the southern mountains. The highest precipitation intensity should occur overnight as the flow turns northwesterly. We expect the wind to remain reasonable today but could pick up tonight to 25, gusting to 35 from the northwest. Temperatures should remain in the mid 20's today but should drop to near zero overnight.

For the extended forecast, you should enjoy this snow while you can because we don't see any other snow until around mid March.
