You may hear some loud booms off the coast of Seal Beach Thursday morning while the Seal Beach Naval Weapons Station runs the first of several training drills.

“The hour-long exercises will include less than two minutes of weapons firing small amounts of blank ammunition,” officials said in a Facebook post.

Locals may also notice a heavier military presence than normal and hear the “Giant Voice” loudspeaker system being used at the base.

The drill will start some time between 9 and 11 a.m. on Aug. 29. The bay off of Seal Beach will be closed to civilian boats during that time, authorities said.

“The drills are not in response to any specific threat, but are regularly scheduled events to support the training and readiness of Navy security personnel,” the Facebook post said.

There are three similar drills planned for the mornings of Oct. 24, Nov. 7 and Nov. 21, according to the Navy.

Officials said live updates will be posted on the station’s Facebook page, and anyone who wants email updates can sign up by emailing [email protected].
