Daily How Much

Most tundra gets 6–10 inches of annual precipitation—mostly snow—yet wind leaves winter snow cover surprisingly shallow and patchy.

For snow foam, mix 20–40 ml per litre (2–4% PIR) in the cannon; add more only for heavy grime.

For snow foam on your car, mix 1:5–1:10 (or 1–5% PIR); in a 1-L cannon bottle that’s about 100–200 ml of concentrate.

There’s no fixed inch count; leaders declare a state of emergency based on impact, forecasts, and safety needs.

Most cars need 100–150 ml of snow foam in a 1 L cannon bottle; adjust by brand, water hardness, and dirt.

Use 1:5–1:15 in a foam cannon, or target ~4% at the panel; then tweak for dirt level, water, and product strength.

Use tire chains when packed snow or ice continuously covers the road; skip chains on bare pavement.

There’s no single inch count; bus cancellations depend on snowfall, ice, wind chill, and road conditions set by each local district.

Most districts cancel around 4–6 inches, but timing, ice, wind chills, and local readiness can trigger a snow day with less.

Plan on 4–6 inches (10–15 cm) of packed snow for cross-country skiing, with grooming starting near 10 cm once the ground has frozen.
