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.

It marks only the third time since at least 2006 that the highest risk level has been issued the day before an expected outbreak.
