A warm air occlusion or occluded front is less common than a cold occlusion. A warm occlusion occurs as cool air moves rapidly into an area with an existing warm front. The difference from a cold occlusion is that the approaching cool air is not as cold as the retreating cold air in the existing front. In other words, the fast-moving, incoming air is cold, but not as cold as the air mass ahead of it. Precipitation can usually be expected when an occluded front passes through an area. Sometimes a cold front will catch up to a warm front and overtake both it and the cooler air out ahead of it. If this happens, an occluded front is born.
