I'd create a hurricane. Obviously I'd create it, say, if I were hundreds of miles away from home, but I'd want to stand outside and experience one... I think it'd be cool, also to see the destructive power of Mother Nature. TV doesn't do anything justice.
At first, I would zap anyone who uses the phrase, "..and may God strike me down if I am wrong." After some catastrophes that would make me realize the terrible consequences of my powers, I would then swear to use them for good by putting out fires, stopping destructive floods, and making it rain food in third world countries. Oh, and have pouring rain isolated around anyone with a lit cigarette. Hehehe...

I'd charge money to shipping companies to regulate tides, airlines to control turbulence, and news corporation meteorologists for me to tell them exactly what's going to happen. I'd create spontaneous ball lightning inside the head of anyone who pissed me off, or didn't pay up.
I would create an happy glen of peace, having always sun and flowers and everything like that. Then, when many had gathered there to be peaceful, i would create a ring of molten lava around them. Then i give them eternal life, only able to be killed by lava rings. Funny, they never get out.
