Original Entry
With Franklin's ghost now exploring the Pacific, our attention turns to disturbances close to home that are showing some continued signs of development potential.

First, an area of weak low pressure centered offshore of the Volusia coast is expected to continue tracking generally north, and has a low chance of becoming a TD in the next 48 hours. While significant development is unlikely in the face of moderately strong northerly shear and proximity to land, the system could bring areas of heavy rains to portions of Florida, Georgia and South Carolina into the weekend, regardless of development.

Invest 99L, which is the very tenacious wave that we have been following for what seems like years, and at one time had odds of 80%, then down, then up, then down, is now up again. Models do not have a good handle on how this wave will interact with a nearby upper-level low, but shear has been relaxing some. Development sooner rather than later would tend to favor an earlier recurvature out to sea, and so seeing it get a name this weekend could actually be a good thing for interests along the east coast.
