That was Lane Pittman, a Florida man who decided to have a little fun with Hurricane Matthew. (We do not recommend imitating him.)
Pittman blasted Slayer's "Raining Blood" as Matthew rained lots of ordinary rain on northern Florida, and headbanged as only he can. His love of metal has gotten him in trouble before; The Orlando Weekly reports he once played "The Star-Spangled Banner" on guitar and was charged with disturbing the peace.
Here's the video in the original context.
Here's video proof of the guitar solo incident.
And here's the original cut of "Raining Blood."
The National Hurricane Center should try that for the next storm.
