Quick Answer
A good emergency whistle for storm situations should be loud, durable, and easy to use with one hand. It should produce a clear, high-pitched sound that can be heard above the storm's noise. Look for a whistle with a pea that's at least 0.25 inches in diameter.
Choosing the Right Whistle
When selecting a storm whistle, consider the material and construction. Stainless steel or aluminum whistles are more durable and resistant to corrosion than plastic ones. Avoid whistles with sharp edges or points that can cause injury. A whistle with a pea that’s at least 0.25 inches in diameter will produce a louder sound, but may be more difficult to use in cold weather.
Factors Affecting Whistle Performance
High winds and lightning can affect a whistle’s performance. To compensate, choose a whistle with a pea that’s at least 0.25 inches in diameter, and one that can be held in place with one hand. In extremely windy conditions, you may need to hold the whistle close to your mouth and blow with more force to produce a clear sound. In the event of a flash flood or tornado, your whistle may need to be heard above the storm’s roar, so choose one that’s designed to cut through noise.
Additional Considerations
In addition to the whistle’s performance, consider the situation in which you’ll be using it. If you’re in a shelter or a building, a whistle may not be necessary, but if you’re in the open wilderness, a whistle can be a vital tool for signaling for help. Always carry a whistle with you when venturing into storm-prone areas, and make sure it’s easily accessible in your backpack or pocket.
