If you live in Southern Alabama or Northwest Florida, you may hear a loud boom and see plenty of smoke Tuesday morning.
That's because the Air Force is planning its second test of MOABB, a 21,000-pound bomb.
The bomb's name stands for Massive Ordinance Air Blast, but it's been nicknamed the "mother of all bombs".
The Air Force first tested MOABB at Eglin on March 11, just eight days before the United States invaded Iraq.
If the weather cooperates, the test will take place between 9 a.m. and 1 p.m.
