Why Your Resort Guide Should Include the Avalanche Forecast

You're planning a ski vacation, and you've narrowed it down to a few resorts. You've compared trail maps, lift ticket prices, and maybe even the apres-ski scene. But did you check the avalanche forecast? Most skiers don't, even though it's one of the most important pieces of information for making smart decisions about where to ski on any given day. I'm not talking about backcountry touring—I'm talking about in-bounds skiing at a resort. The avalanche danger rating applies to terrain beyond the ski area boundary, but it also gives you a window into the snowpack stability that affects the slopes you'll be skiing, especially if you venture near the edges of the resort or into sidecountry. As a ski editor, I've seen too many skiers treat the avalanche forecast as irrelevant to their resort vacation, and that's a mistake. Here's how to use it to make your trip safer and more enjoyable.

Step 1: Understand the Avalanche Danger Scale

Before you even book your trip, you should know the five levels of the North American Public Avalanche Danger Scale: Low, Moderate, Considerable, High, and Extreme (avalanche.org). Each level comes with specific travel advice. At Considerable, natural avalanches are possible and human-triggered avalanches are likely—that's a big deal. At High, travel in avalanche terrain is not recommended because natural avalanches are likely and human-triggered avalanches are very likely. At Extreme, all avalanche terrain should be avoided because avalanches are certain (avalanche.org). The danger increases exponentially between levels, not linearly, so a jump from Moderate to Considerable is more serious than you might think. Parks Canada strongly recommends avoiding areas rated High or Extreme, and restricting travel to simple terrain or staying within resort boundaries (Parks Canada).

Step 2: Match the Forecast to Your Terrain Choices

Now imagine you're a skier at a resort in the Rocky Mountains, and the forecast calls for Considerable danger at upper elevations. You might think, "I'm skiing in-bounds, so I'm fine." But Considerable means human-triggered avalanches are likely on slopes steeper than about 30 degrees, and those slopes exist inside resorts too—think black diamond runs. The NSAA trail ratings tell you that a black diamond is typically 40% or steeper (nsaa.org), which is well within avalanche terrain. So even though the ski patrol may have mitigated some in-bounds avalanche paths, you should still be cautious about steep, ungroomed terrain, especially near cliffs or rocks. On a Considerable day, I'd stick to blue squares (25-40% gradients) and groomed black diamonds, and avoid any unpatrolled sidecountry gates.

Step 3: Use the Forecast to Pick Your Resort and Day

When you're choosing between resorts, check the avalanche forecasts for the mountain ranges they're in. If one resort is in an area with High danger and another is in Moderate, that might tip the scales. For example, the Colorado Avalanche Information Center provides forecasts for the state, and you can see the danger for each zone. If you're flexible with your dates, wait for a day with Lower or Moderate danger to tackle that double black diamond you've been eyeing. Remember, the ratings are typically given for three elevation bands (avalanche.org), so a resort with a high summit might have High danger at the top but Moderate at mid-mountain—you could still ski safely by staying lower.

Step 4: Respect the Numbers—Fatalities Are Rare but Real

Some skiers argue that avalanche danger is overblown because fatalities are rare. The numbers say otherwise: U.S. ski areas reported 50 fatalities during the 2024-25 season, a rate of less than one per million skier visits (NSAA fatal incident fact sheet). That's low, but consider that nearly half of those deaths were from tree collisions (NSAA fatal incident fact sheet), which are often triggered by a skier losing control—not an avalanche. Still, avalanches do happen in-bounds, and snow immersion incidents, including tree wells, accounted for about 10% of fatalities (NSAA fatal incident fact sheet). The avalanche danger rating isn't just about avalanches; it's a proxy for snowpack instability that can affect tree wells and other hazards. So when the forecast is High, I'd skip the gladed runs entirely.

Here's a quick tip: The avalanche forecast isn't just for backcountry skiers. Even if you never leave the resort, check the forecast each morning and let it inform your run choices. It's free, it takes two minutes, and it could save your life.

What would I actually do? If I'm planning a resort trip, I'd build my itinerary around the avalanche forecast. I'd pick a resort in a zone with Moderate or lower danger for the days I want to ski steep terrain. If the danger rises to Considerable or High, I'd shift my skiing to groomed blues and greens, or take a lesson to work on technique. I'd also carry a beacon, shovel, and probe even in-bounds, because you never know when you might need to help someone else. The forecast is your best tool for making smart decisions—use it.
