Sleet can accumulate like snow and cause slick roads.
Freezing rain is rain that freezes after it strikes a cold surface such as a tree, a sidewalk, or a car. It forms a sheet of ice and is extremely dangerous. When measuring ice , measure the thickness of the glaze on trees or wires. Report what is on the ground separately since it might be a mixture of snow, sleet, and ice or a different thickness due to surface temperature differences. Please tell us as much as you can.
