Tropical Storm Danny will be recurving northward, just like Bill did, and spare the mid-Atlantic coastline any serious weather impact. At the most, it seems as of this writing, Danny will force some high ocean swells inducing rough surf, but high winds are not in the cards.
In terms of rain, coastal areas may feel some, but probably not much, of the fringe moisture on the western periphery, but any inland showers will not come from Danny, but instead from an approaching front.
The expected recurvature is typical for tropical systems, but so far this season it has occurred quickly. This is in large part due to the unusually pronounced southward displacement of the northern jet stream, the same set-up that kept us so cool earlier in the summer. These strong upper-level winds also help tear apart any developing tropical systems.
