Reports of the snowpack collapsing or "whoomping" continued on Friday. This is a BIG red flag for avalanche danger. Buried persistent weak layers of sugar snow lurk underneath the new snow from earlier this week. These persistent weak layers are collapsing and causing the "whoomping" noise. It will most likely take some more time before these layers completely stabilize and stop producing avalanches.
These buried weak layers of snow can be found in many locations around the compass but are the most dangerous on the north through east facing slopes that have received the biggest amounts of wind drifted snow on top of them.
