The National Hurricane Center has updated their outlook to include two risk areas. The first, identified as invest 94L is centered 250 miles southeast of Wilmington, North Carolina. This surface low developed along with an occlusion that will become subtropical over the next few days as it passes inland and weakens.
In the wake of 94L the second tropical disturbance 93L will deepen as it moves northward toward the New England states becoming an extratropical cyclone. The remnants of 94L should spur baroclinic deepening as the system progresses over the weekend. This will spawn heavy wind and rains with possible flooding along the coastal and inland areas. Special attention should be paid to the resulting strong rip tides with the accompanying erosion and over-wash issues.
Below are two graphics presenting one view for the upcoming weekend that include a 7 day animation for each product (click for full size). The first is is an overlay of forecast mslp (mean sea-level pressure) and BL (boundary layer winds) winds. The second is a loop of forecast significant wave heights.
