HOWEVER...UNCERTAINTY REMAINS HIGH ON THE EVENTUAL TRACK OF ANY TROPICAL SYSTEM REACHING THE GULF OF MEXICO DURING THE PERIOD. THE GFS SHEARS OUT A TROPICAL SYSTEM IN THE INCREASING WESTERLIES BY MID WEEK...BUT GENERALLY KEEPS ANY ASSOCIATED TROPICAL MOISTURE SHUNTED SE OF THE FORECAST AREA. THE ECMWF FROM YESTERDAY NEVER PICKS UP THE GULF SYSTEM AND ALLOWS IT TO MIGRATE INTO SRN TX THROUGH LATE IN THE WEEK.
