(WHAS 11)--If you hear loud booms don't fear.
Marines training at Fort Knox will begin big boom blasting March 19 at 2 p.m.
Back in February, people across Kentuckiana heard and felt booms from Fort Knox.
At that time, they were performing explosion training on a cloudy day.
Those loud booms caused the sound to travel further than usual.
With the rain forecasted you may be hearing more of those booms March 19.
