Secondary Conditions

Frost Buildup of frost that reduces braking power of vehicles.
Slush A buildup of slush on the driving surface as a result of moderate or heavy snow fall when pavement temperatures are at or near the freezing point creating driving conditions that may cause an unsuspecting driver to lose control of a vehicle.
Heavy Snow More than 8 cm of loose snow partly covers or covers the driving surface. Traffic encounters problems when meeting or passing.
Snow Drifts Snow drifts exist on the driving surface at intermittent intervals.
Swirling Snow A condition created by traffic in loose snow that reduces visibility.
Blowing/Drifting Snow Ground drifting caused by winds which may affect surface conditions on the highway, such as sticking snow or may reduce visibility.
Fog Reported only when visibility is reduced.

Track My Plow
