Dense Fog Advisory For Bozeman and Helena Through Tuesday Morning

When it hasn't been snowing, it's been very foggy in the valleys of southwest Montana so far this week. Dense fog has created dangerous driving conditions at times.

There are a few tricks for driving in foggy conditions, and Montanans aren't the best at remembering them sometimes. (The complaining on local driving/weather conditions groups will prove me right on that.) Anyway, this the is most important tip from Weather.gov:

Make your vehicle visible to others both ahead of you and behind you by using your low-beam headlights since this means your taillights will also be on. Use fog lights if you have them. Never use your high-beam lights.

Most counties in western Montana are also expecting a couple more inches of snow through Tuesday morning, with more over the passes. Travel may be difficult overnight due to the slushy roads becoming icy.
