Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Brett Kobernik for Saturday - March 28, 2015 - 6:55am
bottom line

The avalanche danger will rise to MODERATE with daytime heating. Human triggered wet loose snow avalanches are possible. Some natural avalanche activity is also possible. Get off of sunny slopes as they start to get too wet. Keep in mind what is above you as the day progresses as to not be somewhere a wet avalanche could come down from above.




special announcement

THIS ADVISORY IS VALID FOR SATURDAY, 3-28-15 AND SUNDAY 3-29-15. WE WILL UPDATE AS CONDITIONS WARRANT WHICH MAY NOT BE UNTIL MID WEEK.

We are publishing backcountry observations on a daily basis and you can find them all at our NEWEST AVALANCHE CONTENT WEB PAGE.
current conditions

Temperatures continue to warm over the last few days with readings this morning about 5 degrees warmer than at this time yesterday. Most of the higher stations are in the mid 30s to low 40s. Wind is fairly light and variable in direction but mostly from a westerly direction. Skies were clear overnight which should have helped with a refreeze of the snow surface despite the warm temperatures.

I always think it's interesting how the snow surface can freeze solid when the air temperatures are above freezing. How can this happen? It doesn't make sense! It has to do with this "voodoo like" thing we call radiation which effects the snow in many ways. With this freezing process, think of the clear night sky sucking the heat out of the snow. This "voodoo" trumps the air temperatures in some weird way and freezes the snow surface.

description

Wet avalanche activity is your main avalanche concern today. We are in a typical spring pattern where the avalanche danger decreases at night when the snow cools off and the danger increases during the daytime heating as the snow becomes wet. The way to deal with it is early starts and early exits. Think about where your route will put you later in the day so you don't wind up on or below slopes that are becoming unstable.

Here is a great backcountry observation from Mark White where he describes how to mitigate the typical spring time wet avalanche concerns.
weather

Today, Saturday, we'll see clear skies with ridgetop temperatures pushing 50 and light southwest wind. A minor disturbance will produce clouds this afternoon and tonight and bump southwest winds slightly. Sunday will have clear skies and high temperatures a few degrees cooler than Saturday with moderate to light northwest winds. It looks like temperatures warm again slightly early in the week then a pattern shift will cool things down quite a bit for middle to the end of the week. The minor anticipated storm systems don't look like they'll produce much snow accumulations at this time.
