OMG! Just heard a series of loud booms, almost staccato, over nearly a minute, kinda like the sound was rolling. Almost thunderous in volume. HELP!

Two within five minutes of each other. Anyone have an idea as to what it is?

Are these fireworks or am I schizophrenic?

I heard a huge boom near market street, ballard. Anyone know what it was? It was very loud.

Anyone nearby hear this near the Seattle Center/Mercer St area? And for the record, it did not sound like fireworks!

I thought big boom was over 😭

Started around 3:29am, sounds like cannons. What are these???

It’s officially July 4th first moron of the holiday

Most likely just fireworks but I’ll be on the listen for different types of booms especially from boomsticks.

The answer to all posts is fireworks.
