We have moved to Low avalanche danger at all elevations in the Little Yoho area. This is because of a stronger snowpack in this part of our forecast region, and because we have not seen any avalanches release on a persistent weak layer here for weeks. But we remain sceptical of thin snowpack areas, so ease into it.
Winds have been light, but small wind slabs may still exist in leeward areas. Some minor reverse wind effect (NE winds) was noted in alpine areas on Tuesday, but no slab development. No observations have been made above 2800 m.
No new avalanches have been observed or reported in this region for the past 72 hours.
20-25 cm of soft, dry snow sits over the Feb 3 crust which exists in most locations (except high north aspects). This crust has helped to stabilize the snowpack, and at this time is not presenting as a weak layer of concern. This may change in the future if this crust deteriorates (facets), the wind picks up or the sun heats the snowpack. Persistent weak layers remain present in the mid and bottom of the snowpack but are not producing avalanches in deep snowpack areas at this time.
A ridge of high pressure will dominate the region for the next several days bringing mostly blue skies, temperatures from -10 to -20 and light NE winds. No new snow is expected.
