Tropical Storm EUGENE


ZCZC MIATCDEP5 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM EUGENE DISCUSSION NUMBER   8
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
2 AM PDT WED JUL 20 2005
 
EARLIER MICROWAVE OVERPASSES DEPICTED THAT EUGENE HAS BECOME AN
EXPOSED CIRCULATION...WITH REMAINING WEAK CONVECTION CONFINED WELL
TO THE WEST OF THE CENTER. THE POORLY DEFINED CENTER HAS ALSO
BECOME VERY DIFFICULT TO LOCATE IN INFRARED IMAGERY. DRIER AND MORE
STABLE CONDITIONS ASSOCIATED WITH THE MARINE LAYER AND COOLER
WATERS SHOULD WEAKEN EUGENE TO A REMNANT SWIRL OF CLOUDS DURING THE
NEXT 24 TO 36 HOURS...OR LESS. DVORAK DATA T NUMBERS RANGE FROM 2.0
(30 KT) TO 2.5 (35 KT). THE INITIAL INTENSITY IS SET AT A MODEST 40
KT. THE INTENSITY FORECAST CALLS FOR CONTINUED WEAKENING WITH
DISSIPATION OVER THE NEXT FEW DAYS. BECAUSE OF THE RELATIVELY RAPID
WEAKENING TREND EUGENE IS EXPERIENCING...ADVISORIES MAY BE
DISCONTINUED LATER TODAY. 
 
BASED OFF OF THE PREVIOUS MICROWAVE FIXES AND CONTINUITY...THE
INITIAL MOTION IS ESTIMATED AT 305/10. THE OFFICIAL FORECAST TRACK
REASONING REMAINS UNCHANGED FROM THE PREVIOUS ADVISORY....WITH A
GENERALLY WEST-NORTHWESTWARD TRACK THROUGH THE FORECAST PERIOD
WITHIN THE LOW/MID STEERING FLOW OF THE RIDGE TO THE NORTH.
