How was Asheville North Carolina swamped by a hurricane despite being hundreds of kilometres from the sea? Simple: that water was not sea water. It was rain.
The storm was carrying such a vast amount of moisture when it came barreling inland that it dumped entire lakes worth of rain when it collided with the Appalachian mountains.
Why is this being blamed on global warming, you ask? Again, simple: warm ocean waters give both energy and moisture to tropical storms, and the air itself is also unseasonably warm, which means it can hold more moisture than normal. The amount of moisture that the air can hold is directly correlated to its temperature, and hurricanes are directly linked to warmth: that's why there is no winter hurricane season.
