#99L has been declared. Most likely thing for Hurricane #Sara to do is loop-de-loop, so don't worry about direction until after Sunday/Monday.

If you look at the SST, the cool pool from #Lee/#Nigel is pretty far east of this track. More likely #99L/#PTC16 gets a boost from the Gulf Stream than suffers a loss from cool pool.

Although also as shown here: 7-day SST trend. Once it passes Gulf Stream, all downhill from there. Green = ~normal.

The system off the Florida coast has now been designated Invest 99L.
If it organizes & becomes a subtropical storm, it will be named #Ophelia.

Regardless of name or PTC designation, it will likely be a wet & windy start to the weekend for ENC.
