The middle part of March brought a series of loading events, dropping 3-5 feet of snow in many locations. Since that time the snowpack has settled, weak layers have adjusted to new loads, and mild weather have all contributed to stabilizing the snowpack. Despite this, it is still remotely possible to encounter the following:
Wet Loose avalanches
Very steep sunlit terrain and steep slopes in the lower elevations hold the potential for low volume point releases.
Give cornices a wide berth. Stay off of them by knowing where they connect to underlying terrain. Minimize your time below them as well.
Weak layers of snow buried 2-5 feet deep exist. The deep slab problem is in a dormant phase but is worth remembering for now. It would take a very large trigger (large group of snowmachines or people) to wake up these layers. Thin spots of the snowpack in very steep terrain would be the most likely place for an outlier event like this to occur.
Keep in mind that LOW danger does not mean NO danger. Continuing to utilize good travel habits will afford the ability to minimize exposure to these exceptions to the current snowpack norms.
It has now been 10 days since any significant precipitation has fallen. Temperatures over the past 24 hours at the Sunburst station (3,812′) have averaged 26 degrees F. Winds there have been very light, averaging 5 mph out of the East with a max gust of 12 mph.
Today will be much like yesterday; sunny and mild with calm winds. Temperatures at 1,000′ will climb into the high 30s F. Winds will be out of the East at 5-10mph.
A very large ridge of high pressure is dominating the weather across most of Alaska. This ridge is preventing any and all moisture from pushing into the region. This pattern is now well established and looks to remain that way through most of the week.
