I found an amazing picture on CNN iReport of a user taking pics of a funnel cloud right over downtown A.C. I actually am very close to where that cloud formed. (I didn't see it though
)It never touched down. This occured back in 7/27/08 where we had nonstop lightning and thunder for over 4 hours. The temp also dropped from 86 to 71 degrees in 10 minutes.
I don't think I've ever seen a funnel right on the shore, just on the mainland.
