Thunder in the San Fernando Valley, to my admittedly flawed and overly dramatic memory, has always been a krak-BOOM (rumble, rumble, rumble, rumble, rumble) thing.
Today, for the first time, we’re having thunder with a krak-boom, krak-BOOM, krak, krak, krak-BOOM (rumble, rumble, rumble).
It’s like… an orbital strike, followed by secondary concussions. (that’s for all you conspiracy freaks who believe the Woolsey fire was created by government laser satellites).
Or… that time when you hit a blaze canister on a grazer with a couple of fire arrows. And it ‘splodes, taking out multiple machine-creatures near it, who end up as secondary explosions? (might have been playing too much Horizon Zero Dawn)
