At noon temperatures in Tuckerman Ravine were in the low teens and winds were mild. I and fellow Snow Ranger Jeff Lane walked in around in the base of the bowl to better understand the effects of yesterday’s (1/2/2022) rain. The National Weather Service reported .17 inches of rain on Sunday. This rain was then followed by trace amounts of snow.
Although the rain totals were marginal the impact on the snowpack has been apparent. A dense and largely impenetrable crust has formed. The new snow that fell following the rain created very small wind slabs in Tuckerman Ravine. In most cases, these slabs were only 1-4 inches thick and touchy. It will be interesting to see how new snow interacts with this crust.
The rain also decreased the size of our snowpack. Shrubs and rocks that were previously covered by snow are now exposed in the upper reaches of many gullies. There is a chance for snow this Wednesday and Friday.
