Ok, let's not get out of hand here . . . when Andrew's northern eyewall rolled over my house, I watched my cars through the kitchen window (only one not shuttered, was protected by overhang of second floor) as sustained winds of 150 mph with gusts of 200 blew through my parking lot. No cars moved; even my old slab sided '89 Jetta barely shook on her springs.
Tornados, yes, and that accounts for some heavy things moved, but debris that travels far is usually large light structures like aluminum or wood sidings, etc. Small, heavier things, like roof tiles (and yes, they can be ripped off), the 3-story apt complex across the way lost much of their roofs, and every windshield and window of every car in their parking lot was shattered, not to mention dents in the bodywork. However, we didn't get a single one in our lot, right next door. My Jetta had scratched paint and glass from the shingles of our roof, but no other damage and no car was moved an inch.
I will say this though; you know you're in trouble when the lightning is GREEN! (comes from having so much rain in the air, I think)
I saw 2 flashes of green lightening in a Texas thunderstorm one night. That is very eiry sight! Never heard any explanation for it.
You know you're in trouble when the natural gas mains break and the downed power lines ignite the gas *awhoom* and the howling wind blows it out, and this cycle repeats over and over again.
When the wind rips street signs loose from their metal poles and they go spinning through the air like lethal frisbies.
When the flooding water causes red ants, snakes, and rodents to seek shelter in your house.
That's remarkable; out west it's not unusual for 60-70 MPH winds to overturn trucks and trailers on the highway -- especially on the lee slopes of the Rockies. I was directly behind a travel trailer when that happened.
