The avalanche hazard is HIGH today for upper elevations, CONSIDERABLE at mid elevations and MODERATE at low elevation. Travel in avalanche terrain is not recommended.
Dangerous avalanche conditions exist with natural avalanche activity possible to likely at mid to upper elevations. Keep in mind that large avalanches will be able to run long distances. Pay attention to what is above you as avalanches will have a far reach. Any avalanche at any of the elevations bands will be dangerous.
Poor visibility will make safe travel in the backcountry difficult to impossible today.
If you do decide to enter the backcountry, stick to the lowest elevation bands below 2500', slopes 25º or less, and out of the runnout of steeper slopes from above. Make sure someone back home knows the specific locations you intend to travel and check back out of the backcountry with them at the end of your day.
Let's all make this an avalanche free, holiday weekend!
