Rain is in the forecast today and with the lack of an overnight freeze and warming temperatures today you might see or trigger some loose wet slides in steeper terrain. The new snow from Wednesday is well bonded to the snow beneath but it could create some wet sloughs as it absorbs rain or warms up excessively. We foud the snow on a south aspect to be near isothermal meaning it will break down more quickly to heat input.
This is our last forecast of the season. If you go out in the mountains this weekend you'll notice the difference in the snow conditions as your aspect changes. We even found powder snow on a west aspect. Southerly aspects were heating up and you'll have to be aware of rotten snow that could suck you in. A good way to travel right now is by ridgetops where you can easily sample the snow on multiple aspects. If it feels good, dive in, if not, get out. Ben and I had a great slide down this ridge back to our sleds on the Keeler road. The snow got less supportive as we descended. The wind helped us out yesterday and kept the snow surface from heating up and getting too manky. Thanks to everyone who submitted observations, came to our classes, attended Pit Chats, thanks to the Friends of IPAC. It's all about creating a community of people that enjoy getting out in the mountains in the winter. If we keep building that awareness we'll pass on good safe travel habits to the next generation. We'll post the spring touring tips next week to wrap things up for 2019.
Today to Saturday night: Several rounds of precipitation are in store as a series of waves pass through. This will be mixed with a risk for thunderstorms, some mountain snow, and breezy conditions. The first wave passes this morning and early afternoon with an area of precipitation lifting across the Columbia Basin and northeastern mountains, before exiting through north Idaho. A brief lull is expected before the second wave moves in and spreads showers from west-southwest to northeast between mid-afternoon and evening, along with the threat of thunderstorms.

Avalanche conditions change for better or worse continually. Backcountry travelers should be prepared to assess current conditions for themselves, plan their routes of travel accordingly, and never travel alone. Backcountry travelers can reduce their exposure to avalanche hazards by utilizing timbered trails and ridge routes and by avoiding open and exposed terrain with slope angles of 30 degrees or more. Backcountry travelers should carry the necessary avalanche rescue equipment such as a shovel, avalanche probe or probe ski poles, a rescue beacon and a well-equipped first aid kit.
