At least seven tornadoes hit Alabama on Saturday, and that number will likely climb even higher later today. The National Weather Service plans to continue looking at storm damage and has several areas that will be visited by storm survey teams today (Monday).

Eight people died in a Kansas highway pileup involving at least 50 vehicles, according to the state highway patrol.
