Flashes near Ocean Beach followed by a loud jet sound with no visible aircraft

I was driving down Fulton around 9:35 when I saw the flashes and heard the booms coming from ocean beach, then after I parked my car 2 minutes later, I heard a very loud jet sound. Like super loud, much louder than normal, except there were no planes in sight besides the very far off ones. I called my partner who lives .25 mile away and she heard it too. Anyone else in the outer Richmond experience this?
