Frostbite may occur in as little as 10 minutes on exposed skin. * ADDITIONAL DETAILS...An arctic airmass will drive colder air and strong winds through Thompson Pass beginning later today.

If travel is absolutely necessary, drive with extreme caution and be prepared for sudden changes in visibility.
