Strong winds have built wind slabs on south facing slopes.
While danger ratings decrease, reactivity may still be found in specific features.
Fresh winds slabs can be found on south facing slopes, while older wind slabs on north facing slopes likely still exist. Watch for crossloading in unusual features like mid slope gullies and rollovers.
No new avalanches have been reported.
During the storm on Monday and Tuesday, storm slabs up to size 2.5 occurred. On Tuesday near Mount Washington, several skier-triggered storm slabs up to size 1.5 were reported from steep or wind-loaded terrain at treeline.
Reactivity in wind loaded features is expected to continue.
Up to 90 cm of recent snow has been transported into wind slabs on south and east facing slopes by strong northwest winds. Expect to find pockets of dense and deep wind slab in wind loaded terrain and crusts or bare ground in high elevation exposed terrain.
The remainder of the snowpack is strong, with numerous hard melt-freeze crusts.
Treeline snow depths generally range from 50 to 150 cm. Snow depth diminishes rapidly below 500 m where there has been more rainfall.
