The 8/31/11am advisory discusses various models and their
northwest-turning projections, noting only a few models still aiming at
the keys. ....I'm actually wondering: How do we keep it off of *Cuba*?

And the crowd roars its approval. Who needs the national hurricane center?
Go west young man, or woman (is Frances a male or female? I suppose female
because of spelling). I can see the signs on boarded windows already:
"Lighten up, Frances!"

I can understand "ridges" very well, but I admit I'm a bit fuzzy on the
whole "trough" concept. I think I read somewhere that it was an elongated
low pressure area, but all I see on the map on weather.com is a long mostly
blue partly red line leading up the Appalachians. I see no indication that
it's a low pressure area, which I understand to be low pressure areas which
rotate counter-clockwise. What's portrayed on the map is what I understood
to be a warm/cold front, not a low pressure area. So what exactly IS that
thing on the map, in layman's terms.
