Ogden Avalanche Advisory

Forecaster: Bruce Tremper

SPECIAL ANNOUNCEMENT

We will be doing intermittent afternoon avalanche advisories this week, as conditions change. We expect to update this again on Friday.


BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

The avalanche danger is mostly low with the only avalanche activity expected to be loose snow sluffs within the new snow, especially with daytime heating. If substantially more than the few inches of snow fall overnight or on Wednesday, or if the winds blow hard, you can bump the avalanche danger up to Moderate.


CURRENT CONDITIONS

We got a little bit of snow this morning--1-4 inches with the most at Alta, as usual. The snow settled quickly because it fell on a wet, warm, snow surface and the afternoon sun helped to cook it down. The forecast is for 1-2 more inches overnight.

Here is the SNOTEL plot from Brighton. The red line is last season, the blue line is average, one of the green lines is 2007, the next lowest snow year to date. The green line that stops at the present time is this season. At least for the Brighton station, this is the lowest snow year on their record but it does not include the very low snow year of 1976-77, which is probably barely lower.


RECENT ACTIVITY

No activity has been reported since the weekend except for minor loose snow sluffs today within the new snow with daytime heating.

Remember you can always check for recent observations or avalanche activity report sent in by the general public or our forecasters on our Current Conditions page.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

There has not been many reports lately and our staff is busy working on spring projects, so the only observations we have are from the few ski resorts still open. They are reporting mostly stable conditions with low danger. The only activity reported was some wet loose snow sluffs due to sun heating of the new snow.

Spring weather forecasting is always very difficult because of the convective nature of the weather. If we get substantially more than the 2-3 inches forecast overnight and on Wednesday, or if the wind blows much more than forecast, you can expect some activity within the new snow such as soft slabs or wind slabs. As always, you should jump on test slopes or test how well the new snow is bonded as you travel by occasionally digging down with your hand.

Note: the grey areas on the danger rose above indicate bare ground.


MOUNTAIN WEATHER

The forecast if for another weak disturbance to go by tonight into Wednesday, which should give us another 1-3 inches of new snow. The wind is not expected to blow very hard, 15 mph from the south. Overnight lows should be near freezing with the daytime highs around 40 degrees. Wednesday should be partly to mostly cloudy but the sun could peek through at times. We should have continued unsettled weather linger into Thursday but they it looks like a strong warm up for the weekend.

Be sure to monitor the National Weather Service for the current weather forecast and monitor the Snow Page for current weather conditions.
