A short routine that works for any Utah pass:
1. UDOT Traffic (udottraffic.utah.gov): the mountain pass weather stations give air and road-surface temperature, wind and gusts, and road condition.
2. UDOT's current traction restrictions and its chains-required map.
3. Cameras: look, don't guess.
4. The NWS forecast and alerts for the pass (weather.gov, Salt Lake City office for Soldier Summit and Parleys).
5. Check again at your last fuel stop before the climb. Conditions on a pass can change between the valley and the top.
Our https://thetruckershub.com/roads/ page collects some of this with the time of each update, but the official page always wins.
