Abstract: Fredston and Fesler (1994) used a triangle as a graphic organizer to represent three factors that produce avalanche instability: terrain, snowpack and weather. When people are placed in the middle of this triangle we now have a hazard. This has aided thousands of students to clearly understand what produces avalanches. The weather side of the triangle is often the least understood by participants in avalanche courses. This poster carries the triangle graph a step further to aid students in understanding the important weather factors in avalanche formation. The three primary weather factors are presented as parts of a triangle graphic organizer. These factors precipitation, wind, and temperature - are each broken down into three more subcategories. This graph of three triangles arranged into one aids students to remember nine important weather factors.
