山を楽しみ、無事に帰りましょう。
Snow Now は、山を愛し、山に敬意を払う人のために作られています。自分の力量の範囲で滑り、周りの人に気を配り、自分で判断してください。私たちは役に立つ道具のひとつであり、最終的な答えではありません。
The short version
- 山は危険で、命を落とすことがあります。行動は自己責任で、判断はあなた自身のものです。
- Snow Now は目安であり、保証ではありません。予報、地図、ルート、記録は、間違っていたり、遅れたり、欠けていたりすることがあります。
- Snow Now だけを情報源にしないでください。公式の雪崩情報と、スキー場や現地の情報を確認してください。
- コース外に出るときは、必ず先に現地の雪崩予報を確認してください。
- 不安なときは、資格のあるガイドやインストラクターを頼んでください。適切な安全装備を持ち、使い方を身につけてください。
- ジャンプや速度などの数字は楽しむためのものです。数字を超えるために危険を冒さないでください。
- ほかの人の投稿はその人自身の言葉で、Snow Now は確認していません。
What Snow Now is
Snow Now is a free service made and run by Harry Bowerman. It shows weather and snow forecasts from several weather models, maps, webcams, ski runs and routes, and lets you record and share your days. It is for general information and enjoyment. It is not a safety service, a guiding service or professional advice.
Forecasts and snow
- A forecast is a computer’s estimate. Mountain weather changes fast and can be very different from the forecast, from one slope to the next, and from one hour to the next.
- Forecast snowfall is not a measured snow depth and not a snow report. Only snow measured on site is called a snow report.
- Data comes from other services and can be late, incomplete or unavailable.
雪崩
- Snow Now does not judge avalanche danger. Where avalanche information is shown, it comes from the official avalanche services, and it may be out of date or missing for your area.
- Always read the full, current bulletin from the official avalanche service for where you are going, every day you go.
- If you leave marked and open pistes, always check the local avalanche forecast first. Go with the right training, a transceiver, shovel and probe, and with people who know how to use them. If in doubt, don’t go, or hire a qualified mountain guide.
- No app can tell you a slope is safe.
Maps, routes and following a route
- Maps, ski runs, lifts, trails and routes come from open map data and other people. They can be wrong or out of date. A line on the map does not mean the way is open, safe, legal or within your ability.
- Planned routes, times and heights are estimates. Offline maps may be incomplete.
- GPS on a phone can be wrong by many metres, more so in steep ground, forest and bad weather. Batteries run down faster in the cold. Do not rely on your phone alone to find your way: carry a map and know how to use it.
- Follow the rules, closures and signs of the ski area and the place you are in. They always come before anything shown in Snow Now.
Recording, speed, jumps and badges
- Speeds, distances, heights, jumps, turns, possible falls and badges are worked out from your phone’s sensors. They are estimates and can be wrong.
- They are for fun. Do not ski, ride or climb faster, higher or harder than is safe for you and for the people around you in order to beat a number, earn a badge or climb a leaderboard.
- Snow Now does not call for help. “Possible fall” is only a mark on your recording. In an emergency call the local emergency number (112 in Europe).
- Look where you are going, not at your phone.
Posts by other people
Photos, reviews, snow and conditions posts, and avalanche observations are written by the people who post them. They are their own words and opinions, not checked by Snow Now, and not an official bulletin. Treat them as one person’s view at one moment. You can report any post.
Your responsibility
- You are responsible for your own safety, for your decisions, and for those in your care.
- Know your limits, check the conditions yourself, and be ready to turn back.
- Take lessons from a qualified instructor if you are learning, and hire a qualified guide for ground you don’t know.
- Have insurance that covers what you are doing, including rescue.
Our responsibility
Snow Now is provided free and “as it is”. We work hard to make it accurate and useful, but we do not promise that it is correct, complete, up to date or always available, or that it is suitable for any particular purpose.
As far as the law allows, Snow Now and Harry Bowerman are not responsible for any loss, damage, injury or death that comes from using Snow Now, from relying on what it shows, or from it not being available.
Nothing in these terms takes away rights the law gives you that cannot be taken away, or limits responsibility that the law does not allow to be limited.
Changes and contact
If these terms change, this page and the date at the top will change, and the app will ask you to read the short version again. Questions: info@gradientwx.com. How we handle information about you is on the privacy page.
