Alabama was bracing for Round 2 of severe weather on Saturday. Round 1 started early this morning and prompted two tornado warnings and multiple severe thunderstorm warnings but no damage has been reported so far.

An "outbreak" of tornadoes and severe thunderstorms is expected through Saturday night in Alabama, Mississippi, Louisiana, and other southern states.

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?
