“Locked in place” has been our common theme over the last week. The snowpack has gone through many temperature swings- melting to refreezing- and now sits frozen, hard, and strong. The strength of the snowpack without the presence of any active weak layers makes for stable conditions and unlikely avalanche activity.
The warm temperatures that caused the melting didn’t go much higher than 4000 feet. Consequently, we can’t say the same generalizations about the higher peaks. You are more likely to find softer snow and possible unstable snow in these areas that escaped the rain and warm temperatures.
It is March, and our sun exposure is getting to be significant. South facing slopes are getting just enough solar heat to cause “roller balls” during the afternoon. Overhanging cornices, which tend to be large and mature this time of year, should be approached with caution or avoided all together. No matter how stable the general snowpack is, cornices can be the exception.
The last shot of measureable snow (1-2″) was on Wednesday. That storm offered significantly more to Anchorage and Hatcher pass. Since then the weather has been mild with below freezing temperatures and light wind.
Look for sunny skies this morning and increasing clouds towards the afternoon. Variable wind to 10mph. Temperatures reaching the low 30s during the day.
A …WINTER STORM WATCH FOR HEAVY SNOW AND BLOWING SNOW IS IN EFFECT FROM MONDAY MORNING THROUGH MONDAY EVENING NORTH OF MOOSE PASS…! Yaaay! Snowfall amounts are likely 6-12 inches, possibly 18 inches in some areas.
