Questions and answers

A map of live outdoor cameras in places that get snow. Each camera is paired with the weather at its exact coordinates and given a verdict: snowing, not snowing or unknown. Tap a camera to watch the live video, which is always the final word.

Ski resorts, towns and individuals who run public live streams, plus cameras visitors submit. We embed the operator’s own stream; we do not host or alter the video. Every listing has to be live video, and the site checks that before it shows a camera and keeps checking afterwards.

From the weather at the camera’s exact coordinates, read from the Open-Meteo model. It counts as snowing when:

• the model reports snow, or measures snowfall in the current hour, and it is 2°C or colder at the camera (up to 4°C when the air is dry enough for wet snow to reach the ground);
• there is precipitation at 1.5°C or colder that the model did not label rain;
• it snowed within the last two hours and it is still cold and overcast.

A reading above about 35°F with no snow in its description is rejected.

Tomorrow.io and OpenWeather are consulted only when Open-Meteo fails. A fallback reading can fill in an unknown status and refresh the temperature, but it cannot flip a camera from snowing to not snowing or back. Every reading records which provider produced it, and the camera page shows that provider next to the verdict.

A check runs every 15 minutes and works through the cameras in batches, and an hourly job refreshes the stalest readings first. Each camera page says when its reading was last checked. The live video itself is real time.

For each camera we pull ensemble forecasts through Open-Meteo from ECMWF, NOAA and, where available, Germany’s weather service DWD, up to 122 runs in all. Each run is one plausible version of the next few days. The camera page says exactly which models and how many runs went into its forecast. A run counts an hour as snow when it puts down at least half a millimetre of snow and the air at the camera is 2°C or colder. The percentage is the share of runs with snow in the next 48 hours, and the start window covers the middle half of those runs.

Likely means 60 percent of the runs or more show snow, possible means 30 to 59 percent, and a small chance means 10 to 29 percent. Below 10 percent the page says there is no snow in the forecast. The start window is never shorter than three hours, because the models are not precise to the hour.

Every weather reading we take includes the next 48 hours from the regular forecast. A camera gets the full ensemble when some hour is 5°C or colder with at least a 10 percent chance of precipitation, when the model shows snowfall, or when it is snowing. Anywhere else the page says there is no snow in the forecast. The ensemble is refreshed about every six hours, and one older than 12 hours is not shown.

Every forecast is logged when it is issued, including the ones that say no snow. Two days later it is checked against the readings at the camera. Once there are enough to judge, camera pages show how often it snowed when we said snow was likely. Until then they say the record is not in yet.

Most forecast runs had snow starting by that hour, but the latest reading at the camera does not show it. Forecasts are often an hour or two early or late, and a shower can miss a camera entirely, so the page says both things instead of picking one. The live video is still the final word.
