INFRARED SATELLITE IMAGERY CONTINUES TO INDICATE FURTHER DISSIPATION
OF DEEP CONVECTION ASSOCIATED WITH FERNANDA. A 0236 UTC QUIKSCAT
PASS INDICATED 45 KNOT UNCONTAMINATED WINDS WHEN THE SYSTEM HAD
MORE DEEP CONVECTION. THE DECREASE IN CONVECTION...AND ASSOCIATED
SPINDOWN...WARRANTS BRINGING DOWN THE INITIAL INTENSITY TO 40
KT...WHICH MAY BE GENEROUS. FERNANDA IS EXPECTED TO REMAIN IN THE
HARSH DRY STABLE ENVIRONMENT DEPICTED IN WATER VAPOR IMAGERY.
THEREFORE THE INTENSITY FORECAST CALLS FOR A GRADUAL WEAKENING AS
THE SYSTEM CONTINUES TO MOVE WEST-SOUTHWESTWARD THROUGH THIS
ENVIRONMENT. 
 
INITIAL MOTION IS ESTIMATED AT 250/6. THE MAJORITY OF THE DYNAMICAL
MODELS AGREE ON A CONTINUED WEST-SOUTHWESTWARD MOTION THROUGH THE
FORECAST AS A SURFACE/LOW LEVEL HIGH NORTHEAST OF THE HAWAIIAN
ISLANDS SLOWLY BUILDS SOUTHEAST DURING THE NEXT FEW DAYS. THE 
UKMET AND THE DEEP LAYERED BAM REMAIN OUTLIERS AND ARE CONSIDERABLY
TO THE RIGHT OF THE OTHER GUIDANCE. THE OFFICIAL FORECAST REMAINS
UNCHANGED FROM THE PREVIOUS PACKAGE WITH A GENERAL
WEST-SOUTHWESTWARD MOTION THROUGH THE PERIOD.
