When the weather people talk about 'tropical storm force winds' and '60 mile an hour winds...what does that mean?
Richard Lewelling of the Weather Channel says wind speeds of 40 miles an hour require you to sit up and take notice.
"At 40 to 60, you're going to see those large trees start to move, and if you stand outside in that strong a wind gust, you're going to start feeling resistance against your body," he said.
When the winds get to fifty miles an hour, you start to see some destruction.
"You start dealing with branches of trees starting to break off, and if they fall onto power lines those are going to start coming down, too," he said. "So the stronger the winds you get above 50 miles an hour, you might start seeing some shingles blown off of houses, and see some trash cans blow down the road."
And after that, it goes downhill from there.
"If you get up above 55 to 60 miles per hour, you start talking about the possibility of structural damage to houses, and trees coming down as a result of those wind gusts."
