Daily How Much

Heavy snow typically means 2+ inches per hour or 4–6 inches within 12–24 hours, based on National Weather Service criteria.

Many districts cancel around 3–6 inches when timing, ice, wind chills, and bus routes make travel unsafe.

A dusting of snow means a light coating, often near a trace and usually well under half an inch.

There’s no single inch threshold; states declare a state of emergency based on impacts, forecasts, and local NWS criteria—not a universal snow total.

A snow storm usually means widespread heavy snow near 6+ inches in 12 hours or 8+ inches in 24 hours, with local thresholds.

Snow showers usually drop from a coating to a few inches, with totals driven by brief, spotty bursts.

Yes—when new snow reaches 6–12 inches in 24 hours, most skiers call it a powder day, with local thresholds shaping the call.

One foot of snow equals 12 inches of snow depth; water and weight vary with snow type.

Twenty pounds per square foot of snow equals roughly 8–48 inches of depth, depending on density from wet pack to light powder.

At 30 psf, snow depth ranges from about 12–72 inches depending on density and whether it’s powder, packed, wet, or ice-crusted.
