SAN ANTONIO (KTSA News) -If you live near JBSA-Fort Sam Houston you may hear some loud booms between 7 a.m. and 10 a.m. Monday.

The installation is celebrating the U.S. Army North change of command from Lt. Gen. Jeffrey Buchanan to Lt. Gen. Laura Richardson, and cannon fire is a traditional part of the ceremony.

Fifteen volleys will be fired around 7 a.m. Monday and you can expect to hear another 15 volleys starting at around 9 a.m.

The canons are firing blank rounds with no projectiles, but the noise and vibration can be heard and felt for long distances around the installation on New Braunfels Avenue and IH 35.
