A Stationary Front is a front with very little horizontal movement. The line
alternates with orange and blue sections which point in opposite directions to
symbolize little movement.
An Occluded Front is where a cold front has overtaken and merged with
a warm front. The line alternates with the blue triangle and orange half moon
symbols on the same side of the line pointing in the direction the front is
moving.
