    2018 Atlantic tropical depression/storm/hurricane tracks so far:

    A persistent area of "disturbed" weather is over & near Hispaniola & Puerto Rico producing heavy rain at times.  Mid & upper level shear should limit overall development - typical for this time of year though there may be some strengthening east of Florida thanks to interaction with a strong upper level trough that will be moving into the Eastern U.S.  The disturbance will move more north to the east of Florida then finally a recurve to the northeast upon a merger with a cold front late this week into the weekend.

    The band of clouds over the Eastern U.S. below is in association with the upper trough & surface cold front.  As this upper system consolidates & intensifies by late week, the strong upper level trough will insure that '96-L' turns north then northeast well to the east of the U.S.
