We all hear the terms when there's a threat of severe weather. But what does each alert mean, and how does it affect you?

A destructive wave of storms swept into Alabama on Saturday, bringing with them a rarely-seen threat level for possible long-track tornadoes, winds of up to 70 m.p.h., golf ball-sized hail and torrential rain.

The National Weather Service has issued a tornado warning for Lauderdale, Colbert, Franklin, and Lawrence counties.

A tornado watch was released by the National Weather Service on Saturday at 2:39 a.m. in effect until 10 a.m. for Colbert, Cullman, Franklin, Lauderdale, Lawrence, Limestone, Madison and Morgan counties.
