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

    A persistent area of "disturbed" weather - a large cluster of showers & t'storms with an active tropical wave - 96-L - continues moving west several hundred miles east of Puerto Rico.  Some gradual development is possible upon approach to the Northern Lesser Antilles & Southeast Bahamas over the next several days.  From there it looks like a 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.  

    So tropical development - possibly "Patty" - with this system is something to watch.  It does appear mid & upper level shear will be rather strong which should limit the overall intensity of '96-L'.  With movement east of the U.S. east coast, it would appear any impacts on Jacksonville & the local area would be minimal.
