characteristics over the next few days as it moves north-
northeastward, remaining offshore of the northeastern United States.
Additional information on this system can be found in High Seas
Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...low...10 percent.

Under some pretty stout shear (obvious on satellite, 50 knots per CIMSS), but in a season where the MDR tropics are hostile, this is probably the area to watch. It has an elliptical but closes low level circulation. There is some model support for a weak low forming but it'll have a rough time under that much shear.

The other now detagged area is the non-tropical disturbance in the Gulf, it may not be closed at the surface, but it has S winds to the E and NE winds to the W.
