intensity.. you usually wait for a storm to develop before worrying about such things. all i can give you is a canned climo answer.. if it stays weak it just goes west into central america. if it deepens, it would probably be due to some kind of ridging, which naturally implies upstream amplification.. so then it would have a northerly component. so.. if unlikely a weak system would threaten.. if it's coming it will probably be more than the recent flurry.. edouard, fay, gustav.. and now hanna.. of weaklings.
not being condescending, but there are natural limits to my willingness to speculate... not going to elaborate on something im not convinced will ever exist.
