TROPICAL STORM GUSTAV...
THINK THE NORTHEASTERN SYSTEM THE MODELS SPIN UP IN THE 60S
LONGITUDE WELL TO THE EAST-NORTHEAST OF GUSTAV WILL HAVE LITTLE
IMPACT ON GUSTAVS FUTURE TRACK OTHER THAN LEADING TO SLOW
MOTION...WHICH WAS SEEN WITHIN THE MEAN LAYER WINDS OF THE 00Z
ECMWF WHICH ADVERTISED WEST-NORTHWEST STEERING OF 5 KNOTS NEAR THE
NHC TRACK. THIS CONTINUES TO BE SHOWN THE 12Z GUIDANCE SUITE...AS
THE GUIDANCE NOW LIES WEST OF THE NHC TRACK. DUE TO A LACK OF
SEPARATION BETWEEN GUSTAV AND THE SYSTEM IN THE ATLANTIC
SUBTROPICS EARLY IN THE PERIOD...CHOSE TO DEPICT THE SYSTEM
EAST-NORTHEAST OF GUSTAV AS A SURFACE TROUGH AFTER COORDINATION
WITH NHC/TPC. GUSTAV IS EXPECTED TO TRACK NEAR THE FLORIDA KEYS
INTO THE GULF OF MEXICO EARLY NEXT WEEK...LURED INTO THE GULF OF
MEXICO BY A MID-LEVEL LOW EXPECTED TO FORM NEAR THE GULF COAST.
