Those booms residents in South Jersey are hearing Saturday morning aren't thunder or military aircraft breaking the sound barrier.

They're artillery fire at Joint Base McGuire-Dix-Lakehurst.

The military base is holding its occasional artillery training this weekend, officials warned on the base's Facebook page.

The activity was scheduled to start 8 a.m. on Friday, but may have been delayed by the series of thunderstorms that ripped through the region.

But residents can expect to hear the booms until Sunday at about 5 p.m.

If it sounds extra loud or closer than usual, that most likely is because of the heavy clouds that haven't moved out of the area yet from the storms, the bas warns.

"We strive to be good neighbors and would like to thank everyone for their patience and understanding while we train America's best warfighters!," the post said.
