Apparentl both directions. Despite someone's suggestion it should be closed "for the season...we can send them down through Portland" it will hopefully just be temporary. They have a couple of vehicle accidents and spun out trucks. Somewhere there are 2 semis jackknifed together...but that may be further east.
If I'm awake when either direction reopens I'll post an update. It's snowing pretty darn hard, I'd guess about an inch an hour and it's expected to keep up at this pace most of the night.
Edited to add: WB is closed at MP 56 or 58 (I forget which). EB closure is probably at the 47 but I can't tell for sure.
They are letting WB traffic come all the way up to just before the summit, and they intend to let them go around 10pm, but will close again at 10:30 for Avalanche control.
Haven't heard anything special about EB traffic other than it's closed now.
