I always explained it as a watch was "Watch out, things could get dangerous" a warning was "things are dangerous NOW". Basically be aware versus be active NOW
I was only 2 during PD I, and there's a picture of me standing next to a snow drift in our back yard almost twice as big as me. Still I got to go with Snowmadgeon I. That was just impressive to watch the snow piling up
Thankfully not I. The idea is basically the two are in a straight line, and the ends cause the middle to "snap" like a rubber band. Again, not my idea. I chalk today up to **** happens out of the blue, and earthquakes happen everywhere
