System Approaching Nicaragua
|
I checked it out and that is the tropical wave currently approaching Nicaragua, so I'll assume that you meant to say western Caribbean. NHC expects that wave to move inland - if it hasn't done so already - so I can't figure out what the GFS did what it did. Here is a link to the steering currents (from SSEC, University of Wisconsin) that certainly supports the NHC expectation. I wouldn't worry about it - just an anomaly with the 18Z GFS that hopefully will not repeat on the 00Z run.
