Description of Figure 15-15: Example of Website Showing Current Weather Conditions

A cross section diagram shows the relative elevations of a roadway from Seattle through Snoqualmie Pass to Ellensburg. It is color coded to indicate the roadway temperature (e.g., red is 32 degrees F or less; yellow is 33–38 degrees F). The weather is shown as icons (e.g., clouds with rain, clouds with snow, sun) above the roadway. Wind directions and speeds as well as temperatures are shown for various elevations along the roadway (e.g., Homestead, NE 5 mph 40F).
