Avalanche Information

Friday, April 15, 2005 6pm
Good evening, this is Brett Kobernik with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.  Today is Friday, April 15, 2005, and its 6pm. Well be putting out updates every few days or as conditions change for the next few weeks.

Weather Outlook:
After experiencing cooler temperatures Thursday and Friday the snowpack produced some good corn skiing. Another decent refreeze should occur Friday night then things warm up substantially for the weekend. On Saturday, 10,000 free air temperatures will be in the upper 30s. Saturday night will stay warm and terrain lower then around 9000 feet probably wont get down to freezing. Sunday is warmer yet with 10,000 temperatures in the low to mid 40s. A trof will start to affect the area Sunday through Tuesday bringing cooler temperatures.

Avalanche Information:
I received some reports of the expected wet snow activity from earlier in the week and a somewhat unusual human triggered avalanche that one of our observers triggered on Thursday. It was on a 39 degree southeast facing slope in Bunnels Fork in the Cascade ridge area. It was described as a 6 thick frozen slab that released on wet grains below it. It was 150 feet wide, ran around 2000 feet vertical and the fracture line was up to 16 deep. It was triggered by testing the slope with a slope cut and the skier was almost caught but got off of the slab before it really got going.

This is exactly the conditions we will need to watch for this weekend. The observer noted that he was able to easily identify this weakness by punching through the crust and checking the underlying snow. Dont let a firm snow surface trick you. Do a little investigation to see what is underneath it looking for wet unconsolidated snow.

With a good refreeze tonight, Saturday morning could produce excellent corn conditions, but get after it early as things are sure to get sloppy during the day. With warm temperatures forecast for Saturday night, any refreeze will be shallow and you will need to be very careful on Sunday.

Notices:
Today concludes the Powderbirds heli skiing operation for the season so we will no longer inform you of their daily presense.
