Reports coming out of the range indicate that there has been lots of fresh snow. If you are headed into the range, bring flotation to make travel to and from your climbs a bit easier. Monitor avalanche conditions closely and give your climb the time it needs to shed snow after a big storm.
When the weather changes quickly, having your kit dialed becomes essential. I plan for worsening weather by having my nose guard, goggles, extra buff, big gloves, and handwarmers easily accessible near the top of my pack. My packing changes a bit when I am pulling a sled, versus using just a backpack, but I like to think about order of operations. If the storm is setting in, I want to be able to quickly access first my warm layers, then my tent, without exposing my sleep kit to the elements.
Climb safe and enjoy the powder out there!
The National Weather Service issues a daily recreational climbing report which can be found here (note: the URL has changed from past years and the old one is no longer operational).
