A skiff of alpine snow shouldn't create much new hazard on Thursday. Ongoing rain and a saturated snowpack mean wet avalanches remain possible where lower elevation snow coverage remains.
The upper snowpack has been saturated and weakened by rain. This problem will come to a close once a substantial surface crust forms. Until then, wet loose avalanches remain possible in steep terrain.
A widespread loose wet and wet slab avalanche cycle occurred in the Coquihalla area over the past few days, up to size 2.
Recent observations have been limited.
The upper snowpack has been heavily saturated and weakened by recent rain. A new surface crust has likely formed in the alpine and will extend to lower elevations in the coming days.
The mid and lower snowpacks contain several old crusts but remain generally well-bonded and strong.
Snow depths have decreased significantly as a result of the rain, particularly at lower elevations where the snowpack has been melting at an alarming rate.
