The National Weather Service Forecasts- TODAY...MOSTLY CLOUDY WITH RAIN SHOWERS. SNOW LEVEL 1200 FEET. HIGHS AROUND 41. SOUTHEAST WIND TO 15 MPH.

TONIGHT...CLOUDY. RAIN LIKELY IN THE EVENING...MIXING WITH
SNOW LATE. ACCUMULATION ABOUT 1 INCH. SNOW LEVEL 800 FEET IN
THE EVENING. LOWS AROUND 32. LIGHT WINDS. CHANCE OF
PRECIPITATION 70 PERCENT.

TUESDAY...MOSTLY CLOUDY. A 20 PERCENT CHANCE OF RAIN AND
SNOW IN THE MORNING. HIGHS AROUND 41. EAST WIND 15 MPH.

This mornings temperature on Mt Roberts is the warmest it has been in the last 14 days. With coninued moisture accumulation and as much as an additional 3 degrees of warming expected throughout the day today, avalanche danger remains CONSIDERABLE today.

Spatial variability remains high as we have seen quite a bit of wind in the last 10 days. There is great difference in snow density and deposition between windard, cross loaded, and leeward slopes.

Many weak layers remain present in the snowpack even though they appear to be fairly well bonded and holding weight at this time.

Many weak cornices and overhangs have developed during the last weeks snow and wind events. Consistant loading and warming can create cornice falls that can act as the trigger to release much larger slides.

over the weekend shooting cracks, minor woomphing, sluffing avalanches in the steep areas, slabs breaking out on switchbacks of traverse trails were all noted.

Areas in the backcountry are still quite hazardous at this time.

Please use caution and choose your lines and routes wisely.

Remember. Tranceiver, Probe, Shovel, Partner. Don't leave home without them!

Tip:

For those interested there may still be seats available for the University of Alaska Southeasts Avalanche Level 1 Course.

Avalanche Evaluation and Theory Level 1
University of Alaska Southeast
March 23 - April 4

An intensive course of avalanche study covering rescue, terrain analysis, snow study and stability evaluation, route finding, decision making, and safe travel. Combines both in-class and field oriented backcountry experience as required course components. For more information, contact University of Alaska Southeast.
