Quick Answer
Natural shelters may not be able to withstand sustained high winds, depending on the type of shelter and the wind speed. In general, shelters made from lightweight materials or structures with a low wind resistance may collapse or be severely damaged in strong winds. A wind speed of 50-60 mph can be hazardous to natural shelters.
Evaluating Shelter Types
When it comes to natural shelters, the ability to withstand high winds depends on their design and construction. Leafy trees, for example, can be effective windbreaks, but branches may snap or fall during strong gusts. A cleft in a rock face or a cave entrance can provide some protection, but loose rocks or debris may be dislodged and fall inside. In contrast, a natural amphitheater or a depression surrounded by hills can be a relatively safe location.
Assessing Wind Resistance
The wind resistance of a natural shelter is influenced by its geometry and the surrounding terrain. A shelter with a wide, shallow profile is less susceptible to wind damage than one with a narrow, steep slope. Similarly, a location with dense vegetation or a natural windbreak can help reduce wind speeds and protect the shelter. When evaluating a potential shelter, look for features that can help reduce wind resistance, such as a low-lying area or a group of trees that can act as a windbreak.
Creating a Safe Shelter
If a natural shelter is not suitable for high winds, consider creating a temporary shelter using natural materials. For example, a lean-to structure made from fallen branches and a tarp or plastic sheet can provide some protection. A debris hut or a snow shelter can also be effective, as long as they are designed and constructed with wind resistance in mind. When building a shelter, use sturdy materials, secure them firmly, and angle the structure to deflect wind gusts. This can help ensure a safe and secure location during sustained high wind events.
