Mountain conditions
How to read a ski resort snow report before you go
Which snow number are you looking at?
New snow is an accumulation over a stated period at a measurement location. Base depth describes the snowpack depth at the reported location. A season total is accumulated reported snowfall over the season. A forecast estimates future conditions. Do not substitute one for another when deciding whether to travel.
Read the operator’s definitions. An overnight total may use a different start time from a 24-hour total, and a snow-stake camera may have a scheduled reset. Adding overlapping totals double-counts snow. If the reporting interval is missing, treat comparisons with another mountain cautiously.
A worked example: the bigger number may be older
Mountain A reports 8 inches over 48 hours at 6 a.m. Mountain B reports 5 inches over 24 hours at 7 a.m. You cannot conclude that A had more snow last night. The periods differ and both totals can include snow that fell before the most recent overnight window.
Write each observation as amount + period + location + timestamp. For example: “5 inches / 24 hours / mid-mountain stake / 7 a.m.” That small habit makes it easier to spot old reports, overlapping totals and unmatched elevations. The figures here are illustrative.
| Measure | Useful for | Cannot establish |
|---|---|---|
| New snow | Recent accumulation at a reported point | Coverage on every run |
| Base depth | Depth at a measuring location | How much fell overnight |
| Forecast snowfall | Expected future accumulation | A measured result |
| Open terrain | Operator-reported availability | Future opening guarantees |
Why can the base be wet while the summit gets snow?
Elevation affects the rain–snow transition. The National Weather Service’s snow-level guidance describes the elevation where precipitation changes toward snow; this is not identical to the atmospheric freezing level. A mountain can span that transition.
Compare the forecast snow level with the elevations you expect to ski. If lower and upper terrain sit on opposite sides, do not apply a summit snowfall forecast to the entire resort. Use a mountain-specific forecast and read the forecaster’s discussion when available.

Will the reported snow actually be available to ski?
Use the operator’s lift and terrain status to answer that question. A weather forecast does not establish whether a particular lift will run or when a run will open. Check the terrain relevant to your ability and planned lesson, rather than only a resort-wide percentage.
Look at a camera timestamp before trusting the image. A sunny archived image and a fresh weather report can coexist on the same page. Cameras add visual context at one viewpoint; they do not establish conditions across a mountain.
Use a five-minute departure check
First, open the mountain’s official report and read its update time. Second, note the new-snow interval and measuring location. Third, check the forecast at the relevant elevation. Fourth, check lifts and terrain. Fifth, confirm your route, parking or transit with the responsible operator.
Save the links, not just screenshots. Reopen them close to departure because conditions and operations can change. If reports conflict, keep the conflicting timestamp or location visible instead of blending them into a single confident claim.
For seasonal trip planning, return to the winter outlook and your full budget. A single storm report is useful for an upcoming day; it is not evidence that the same mountain will be the best choice months later.
Straight answers
- Can I add overnight snow to the 24-hour total?
- Only if the operator explicitly defines them as non-overlapping periods. Overnight snow is often already part of the 24-hour total.
- Is the town weather forecast enough for skiing?
- Check a forecast for the mountain and relevant elevation. Town and mountain conditions can differ, especially when the rain–snow transition lies between them.
