It's a little storm that tried to become the first named storm of the 2009 Hurricane season.  In the end, climatology wins out.  This tropical depression had to fight the strong westerly winds at the surface and aloft, which is not conducive to tropical development.  I was able to spot the exposed center in the latest visible satellite image (in the slide show).  The fast winds took the convective thunderstorms away from the surface circulation.  It also had sub par water temperatures as it traveled farther north and east along the Gulf Stream. 

These are two things that change over the summer, making tropical storms more favorable... especially in August and  September.  By then, the waters are often above 80F, and the strong winds that can rip a storm apart, are much weaker.

The latest images are in the slide show below.
