More detailed information about the snowpack: 

Very warm conditions in the BWRA today with temps rising into the low 50's below 9,500' in the afternoon.  The surface of most slopes contained wet snow by the afternoon with southerly facing slopes containing very wet and unconsolidated snow.  Numerous loose-wet avalanches were seen today on all but the most shaded northerly aspects.  Most were small point releases (size D1) but a few were large enough to bury someone (size D2).  Thursday's storm will most likely turn the wet surface snow into a slick melt-freeze crust.
