A Level 3 snow emergency closes roads to non-emergency travel and can bring charges for ignoring lawful orders.

To measure snowfall in inches, use a flat white board, take several ruler readings to the tenth, average them, and clear the board between bursts.

Snow driving safety depends on rate, depth, treatment, and tires; avoid travel during heavy snow (≥1 inch/hour) or when visibility drops.

For driving, snow turns unsafe when visibility drops under 1/4 mile, snowfall nears 1″/hour, or roads stay icy or unplowed.

A good skiing base is 20–40 inches packed, rising to 50–70 inches for rocky, ungroomed, or tree-covered terrain.

For most riders, 2–6 inches of new snow on a solid base gives the best mix of control, speed, and float for snowboarding.

As little as 1–2 inches can be dangerous to drive in when roads are untreated or visibility drops below a quarter mile.

Yes—start snow blowing around 2–3 inches, and clear sooner in heavy, wet snow to stay ahead of compaction.

4–6 inches of packed snow usually works on groomed trails; off-trail or rocky ground often needs 8–12 inches for safe snowmobiling.

For sledding, 2–4 inches of packed snow works; 4–6 inches gives smoother speed on most hills.
