Detailed conditions change faster than they can be reported, and it's almost never clear when that frozen brown stuff is snow, slush, or ice. So we only show general conditions. We can't report conditions on all 32,000 miles of state highways, nor can we possibly report conditions on county and city roads. So a set of major highways in a statewide grid were selected. Hopefully it shows something in everyone's area.
Major routes are the highest priority and receive the most attention.
Thus, minor routes may be in worse condition. The system allows our staff to report conditions at any time. Then twice an hour the system looks for changes. If there are any, it makes a new map and text report. The text report has the time and date that conditions were last reported.
