What Kind of Weather Do Occluded Fronts Bring?

Occluded fronts are characterized by dissipating storms with light to heavy sustained precipitation. While passing overhead, affected regions usually experience varied temperatures and changes in wind direction and speed. Occluded fronts also result in poor visibility and a slight drop in dew point temperatures.

In meteorology, a front refers to a transitional zone that separates two distinct air masses having dissimilar temperatures. Fronts are classified into four: cold, warm, occluded and stationary.

An occluded front is generally associated with areas of low pressure known as depressions. Occlusion occurs when rapidly moving cold front outdistances a slower warm front. An occluded front is typically represented on a colored weather map as a solid purple line with alternating circles and triangles indicating the course of the front. After the front passes, the weather begins to clear.
