Fronts and Lows
• Occluded front: when a cold front “catches up” to a warm
front. This happens because cold fronts typically moves
twice as fast as warm fronts.
• Stationary front: is a front that is not moving forward. This
occurs because the approaching warm front is not strong
enough to force the cold front to continue its forward
– If a stationary front remains stationary for too long, flooding
can occur.
