This is only the second thunderstorm I've ever experienced in Portland. Making it only the second time I've ever heard thunder since moving to Portland. And the first time was pitiful, there was hardly any lightning or thunder. This one, though... wow! Intermittent thunder and lightning, but when it comes it's POWERFUL! Just a few minutes ago there was thunder so powerful and loud that it set off someone's car alarm! They probably didn't find it too amusing, but I did.
