As temperatures begin to increase and the ground warms up throughout the day, the chance of encountering a dust devil also increases. Keep in mind that dust devils usually develop when wind conditions are calm and warming occurs around an intersection of two dissimilar surfaces. If this happens to be an area with grass and asphalt, the dust devil can be difficult or even impossible to see, because it does not pick up much debris. In desert environments, they are easier to spot and avoid, because they are full of dust and dirt picked up off the desert floor. Although capable of growing as tall as 3,000 feet, they can also be as small as just a few feet. No matter what time of year you are jumping, weather conditions must always play a part in your decision to jump or stay on the ground. With spring weather and warm temperatures headed your way, keep an extra-vigilant eye out so you can avoid these sometimes hard-to-see hazards.
