How to read the avalanche bulletin in the Tatras

The danger level is not a grade for how hard the trip is

The five-level scale is necessary, and it is easy to misread. The most common mistake goes: one is safe, two is fine, three means you cancel. Reality is less convenient.

At level one the snowpack is usually well bonded, but an avalanche can still be triggered locally, especially on very steep ground. That is not a licence to walk under cornices, through gullies, and on hard, exposed slopes without judging the situation.

Level two is deceptive in the Tatras precisely because it appears often. The danger is described as moderate, but on the stated aspects and at the stated heights it can be real. A person can trigger an avalanche, especially on steep slopes. In other words: a wide, gentle road can be a sensible choice, and the neighbouring gully at more than 30 degrees a trap.

At level three the situation becomes serious. Avalanches can be triggered by a small extra load on many steep slopes, and natural releases are possible. That does not automatically ban every outing, but it sharply narrows the ground for people without solid winter experience. A valley, a low route in the forest, or a day on skis in a safer place is often a much better plan than an ambitious climb for height.

Levels four and five are not the moment to negotiate with your own ambition. High-mountain goals are out. A photo with a view does not make up for walking into ground where an avalanche can release on its own and travel far beyond the spot where you happen to be standing.

Read the text, not only the big number

The most valuable part of the bulletin usually starts under the scale. Look for the height, the aspect, and the type of danger. If the text talks about north- and east-facing slopes above a given height, do not treat that as a technical extra. It is an instruction about where not to wander in without a reason.

Aspect is the direction a slope faces. A north-facing slope holds cold snow for longer, a south-facing one works faster in the sun, and the wind lays fresh snow on the lee side of a ridge. You do not have to be a meteorologist to use that. It is enough to be able to follow the line of the route on a map and recognise whether you will cross the slopes named in the bulletin, or stand under them.

Pay attention to the height limit. The bulletin may point to a problem above the treeline. A climb through the forest is not then proof that it will be calm higher up. Many people pick up a false sense of safety on an easy path, and then walk thoughtlessly out into open cirques, where the conditions are completely different.

The description of the avalanche problem tells you what to look for. Fresh snow after a heavy fall may not bond to the old layer. Wind-drifted snow builds wind slabs: hard, apparently stable plates that can crack under a load. A thaw and rain raise the risk of wet-snow avalanches, especially later in the day. These are not trivia to read over coffee. They decide whether it is better to leave early, stay in the valley, or change the plan entirely.

The steepness of the slope decides more often than you think

Most avalanches release on slopes of roughly 30-45 degrees. The problem is that judging the angle by eye in the field can be terrible. A wide snow slope can look innocent until you look at the map, or use a slope-angle layer in an app.

You do not have to walk the middle of the slope to be in danger. An avalanche can release higher up and run across your route in a gully, under a wall, or on the floor of a cirque. So look at your feet, and look above you. The climb along the floor of Dolina Pięciu Stawów can lead under slopes that collect snow. A passage through a narrowing, where there is no room to escape, needs an especially cool judgement.

You will not find a sentence in the bulletin that says this particular bend is safe. That is the job of the person planning the day. If you cannot judge the steepness, the exposure, and the line a possible avalanche would take, do not pretend that a weather app will settle it. Choose a route outside avalanche ground, or go with a competent partner.

What to check before you leave

The avalanche bulletin should be one part of the decision, alongside the weather, the trail notice, the map, and the real fitness of the group. Before you leave, go through four specific questions:

• Does the route cross slopes of the stated aspect, at the stated height, or run under such slopes?
• Are there gullies, cirques, steps, traverses, and narrowings on the route, where you cannot leave the dangerous place quickly?
• What has changed since the bulletin was issued: more snow, a stronger wind, sun coming out, a thaw arriving?
• Does everyone in the group have the kit, the skills, and the agreement to turn back without a sulk when the conditions do not match the plan?

The last question is often the hardest. Many bad decisions do not come from a lack of information. They come from the cost of the stay, a day off that is only one day, or pressure from a friend who has been talking about a summit for a week. The Tatras are under no obligation to fit your schedule.

Signals on the ground can cancel the plan

The bulletin is a forecast, and the ground gives you current data. Fresh avalanches on neighbouring slopes, cracks in the pack under skis or boots, a dull whumpf as the snow settles, wind-drifted pillows, and snow building up fast are alarm signals. Do not analyse them until the end of the day. Turn back, or choose ground an avalanche has nowhere to come from.

Do not settle the question of safety with one test either: the track is broken in, someone went ahead of us, or the snow feels hard, so we go. A broken track only says that someone has already been there. It does not say what they knew, how much luck they had, or what will happen after the next gust of wind.

If you are going into avalanche ground, a transceiver, a probe, and a shovel are the minimum, not a talisman. The kit works when the group can use it quickly and practises regularly. For people without a course and without experience, changing the goal is the more honest move than buying a set in a shop the evening before and deciding the problem is solved.

A good winter day in the Tatras does not have to end on a summit. Sometimes the best decision is a calm route in a valley, a hot tea, and saving the goal for conditions that really allow it. The mountains are not going anywhere. An avalanche does not ask how many kilometres you drove to get there.
