Re: something you dont see everyday

What you are seeing is the TUTT, or a Tropical Upper Tropospheric Trough, that is behind Frances and helping to ventilate it. It is really not a steering force, as the trof is expanding a bit as Frances is moving away...in other words, Frances is affecting it, not the other way around....
