  • Issued by Aaron Beverly - Mount Shasta Avalanche Center

Avalanche danger is LOW at all elevations. Natural and human triggered avalanches are unlikely. Normal caution is advised. Icy slopes present dangerous climbing conditions. An ice axe, crampons, and helmet are mandatory if climbing on steep terrain, but realize that self arrest will be difficult.

Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.

    Likely
    Possible
    Unlikely

Exercise normal caution when traveling in the backcountry. This means:

  • Always watch for isolated slabs. Two days ago, wind was still transporting snow onto easterly slopes.
  • Carry rescue gear and know how to use it. Essential rescue gear: avalanche beacon, shovel, and probe.

Forecast Discussion

Scoured icy slopes present slide for life conditions. An ice axe, crampons, and helmet are mandatory tools if attempting a summit of Mount Shasta. Self arrest will be difficult if not impossible.

Snow surfaces around Bunny Flat are extremely icy. Those looking to try out their new sled will find conditions fast and slick. Please be careful! Trees do not budge when an out of control sledder hits them.

Cold temperatures and dry weather have kept conditions mostly unchanged throughout the forecast area. Temperatures at the Old Ski Bowl have ranged from 8 to 29 degrees in the last 24 hours. East/northeast winds have averaged 9 mi/hr and gusted up to 31.

A tour of Castle Lake saw a mix of breakable and supportable crusts on sun exposed aspects. Shady areas below heart lake still retain a few inches of dry snow. Height of snow is around 80 cm (31 in). The lake seems to have a supportable layer of ice in most places and may be ready for ice skating. Exercise caution, though, as some thin layers were seen near shore around submerged logs.

No signs of instabilities have been observed. Overall snow surfaces are challenging: bulletproof ice, breakable crusts, sastrugis, scoured ridge lines, and chalky gullies.

Weather and Current Conditions

Weather Summary

High pressure will continue to influence the region until Friday.

Freezing levels begin to increase today and will top out at over 9,000 feet Wednesday and Thursday. Winds should begin to taper off today and tonight giving the upper mountain a break from the pummeling it has been receiving.

This weekend, a new set of systems will bring precipitation and snow levels below 5000 feet.
