Quick Answer
A well-configured tarp can provide a decent level of protection from winter storms, but its effectiveness depends on the tarp's size, material, and the way it's set up. A proper configuration can help to reduce wind-driven rain and snow, but may not completely prevent cold air from entering the shelter.
Choosing the Right Tarp
When it comes to winter storms, it’s essential to choose a tarp that’s made of waterproof and breathable material, such as nylon or polyester. A tarp with a minimum size of 10 feet by 12 feet is recommended to provide adequate coverage and protection. Consider a tarp with a durable ripstop weave and a water-repellent coating to ensure it can withstand harsh weather conditions.
Setting Up the Tarp
To set up a tarp effectively during a winter storm, use a sturdy tarp pole or a modified ski pole to create a stable anchor point. Attach the tarp to the pole using a secure knot, such as the bowline or the trucker’s hitch. Consider using a tarp with a built-in grommet or a reinforced eyelet to make attachment easier. The tarp should be pitched at an angle of at least 45 degrees to allow snow to slide off and to prevent wind-driven rain from entering the shelter.
Additional Techniques
To further enhance the effectiveness of your tarp configuration, consider using a snowload attachment point or a snow anchor to secure the tarp in place. You can also use a tarp clip or a carabiner to attach the tarp to a nearby tree or a snow-covered rock. In extreme weather conditions, consider using a space blanket or a emergency bivvy sack to create an additional layer of insulation and protection from the elements.
