If Alabama experiences severe weather, polling hours may be extended upon court order, depending on the severity of the situation, Grace Newcombe, the press secretary for Alabama's Secretary of State, tells CNN.

The election will run as planned today, she said, but Secretary John Merrill has encouraged Alabamians to take extreme caution when traveling to the polls.

Earlier today, two counties in Tennessee delayed voting following the deadly overnight tornadoes.

Tennessee and Alabama are two of the 14 states voting in Super Tuesday elections today.
