[BC] Tornado warnings

[Kent Winrich]

During the Ernesto thingy here in North Carolina, the NWS kept sending out
tornado WARNINGS, but then said that the potential was there for a tornado.
Correct me if I am wrong but that sounds like a tornado WATCH.  Not once did
they say there was one on the ground.  In the Midwest when we got a tornado
warning, we knew we had one on the ground.  Paint me confused.  Do the
different NWS office have different standards?
