Stationary Front
a front that is not moving

When a warm or cold front stops moving, it becomes a stationary front. Once this boundary resumes its forward motion, it once again becomes a warm front or cold front. A stationary front is represented by alternating blue and red lines with blue triangles pointing towards the warmer air and red semicircles pointing towards the colder air.

A noticeable temperature change and/or shift in wind direction is commonly observed when crossing from one side of a stationary front to the other.
