Daytime temperatures continue to rise. We saw new seasonal highs yesterday at the Mt Roberts Tram Summit at 46f degrees.

Temperatures have remained over 40f degrees for the last 24 hours at the Tram summit. Also a new overnight low/hi temp...

In the last week the temps at the Tram Summit evelation have only dipped below freezing for about 6 hours.

We continue to see point release wet avalanches in the region.

The glide cracks continue to expand.

Avalanche danger is MODERATE today with point release avalanches expected.

Be aware that with these extremely warm mountain temps there is also the possibility for those glide avalanches to release.

Please do not walk in the areas above the Behrands Neighborhood in the open meadows also known as the \"AVALANCHE RUNOUT ZONE\"

Please do not park at Snowslide Creek along Thane Road. The cornice there is also quite weak and could fail with these continually warm temps.

Remember the south to southwest facing slopes will also have increased activity due to the direct sunlight expecially later in the day.

Have a great day and be careful out there...

Tip:

Here is a link to an interesting article from Montana.

It discusses how when you get moisture that continues to drive deeper into the snowpack... and you get no overnight freezing in the snow... how a small avalanche can step down into deeper weak layers... creating large avalanches...

When you are out skiing in the spring... knowing you might see small wet slides... Do YOU know how deep down the next weak layer is in the snopack or how strong it is???
