Another Hurricane Coming?

Dean did head straight west, and it hit Mexico just as the last runs of the Global Forecasting System said it would. After that it turned really quiet. But now things are heating up again.

First of all there is Invest 95L. This popped up all at once recently, after a cold front came thorugh last week. I am wondering if it will develop into anything. If it does, it is likely to go to the east, but still I am watching it because it is close to here in Virginia and North Carolina.

Then there is Invest 94L. It is in the southern Atlantic Ocean, approaching the Caribbean. So I tried to run GFS and see what it says about Atlantic storms heading here. Here are the results of GFS runs:

2007 August 27
18Z - makes a beeline for the Outer Banks, like Isabel
2007 August 28
0Z - hits southern Florida, and probably would go into the Gulf, but can't tell as it goes out of range of the model.
6Z - misses the Outer Banks and heads for the Canadian Maritimes, striking there out of range on the 16th of September.
12Z - skirts up the east coast of Florida
18Z - heads straight for the Outer Banks, to strike there out of range on the 14th.
2007 August 29
0Z - Turns north and goes out to sea
6Z - Turns north and goes out to sea; much weaker than in previous runs
12Z - Turns north by end of run, but it seems largely to have disappeared from these runs.

This storm that I am describing above is not Invest 95L but a storm that comes after it. All the runs say 95L will strike the Leeward Islands as a weak storm and dissipate.

So it looks like it is turning quiet now, after some excitement. The other models show a tropical system developing in the Atlantic and hitting the middle of the Leeward Islands. I guess we will wait and see what happens.
