Everything you need to know is in the report.
To summarize-
Mount Washington's summit has gotten 22" of new snowfall in the past 3 days. That was on top of some snow that had fallen previously as well. Avalanche rating is Moderate to Considerable for larger mid-winter slab avalanches that are likely under human-triggers.
To top it off, there are numerous crevasses/fractures in the Center Bowl and Lip areas that opened up during the March heat that have weak snow bridges over them at the moment from the new snowfall. These crevasses/fractures are the types of things that claimed the life of a hiker very recently.
Anyone heading up this weekend, use your head while your out there, read the report and make smart decisions.
