Well, we'll certainly know if this is true soon enough. Tomorrow's recon estimate position is 20N 58W.....if your prediction is correct, the system will already be going north by tomorrow afternoon.

Florence rather relentlessly traveled West or WNW; exciting many of us amatuers in the US.

Pro Mets like wxman57 kept telling us she would turn NW and then N.

I'll go with what he is saying and expect it to go fishing and, this time; not even affect Bermuda. I recall we were told "it was like talking to a wall" that Florence would not threaten the SE US.

All we need is a concensus from the Pro Mets and we can all watch this perspective Gordon from the sidelines too!

Great Scott!!

It appears to this mad scientist as if 93L is moving just slow enough to avoid getting captured by Florence's trough. The big question now is how long it takes Florence's trough to fill in. 48 hour GFS shows a very pronounced trough that should capture 93L... but it also shows the narrowest wisper of a ridge just above the location of 93L. (It doesnt see 93L yet).

http://weather.unisys.com/hurricane/slp_48.gif

The only way it could avoid capture would be if this slim ridge is enough to hold 93L on a W track until Florence moves north... and 93L would have to almost stall to allow this to happen. 93L is moving slowly W, so it still has the slimmest of chances to avoid capture...

Wxwonder--those are dvorak intenstiy estimates--satellite-based estimates of the storm's intensity. If you want to go into more detail on them, hop over to the "got a question" forum and post over there and someone will give you more on it.

Oods are a funky ride.
At least some aspect of it will not be expected.

So far, Pro Met commenting on it says a fish and it will probably be one.
However, something wacky will certainly occur with intensity or something.

Not very common to have a 30 mph TD. Usually the NHC waits until 35 mph.
