Hurricanes generally travel at speeds of 10-20 mph. They can be slower or faster, but that range is pretty common.

Here's why that speed is important:

* Evacuation time: Knowing the speed helps forecasters warn people in the hurricane's path so they have time to evacuate.

* Landfall impact: A faster-moving hurricane will spend less time over a single location, reducing the overall rainfall and storm surge impact.
