Now displaying a very small 15 nm eye...

WDPN32 PGTW 090300
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TYPHOON 07E (GENEVIEVE) WARNING NR 48//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TYPHOON 07E (GENEVIEVE), LOCATED APPROXIMATELY 821 NM WEST-
NORTHWEST OF JOHNSTON ISLAND, HAS TRACKED NORTH-NORTHEASTWARD AT
11 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A SYMMETRIC, TIGHTLY WRAPPED SYSTEM WITH A DEFINED
15 NM EYE. ADDITIONALLY, A 081952Z SSMIS MICROWAVE IMAGE ALSO SHOWS
AN INTENSE RING OF DEEP CONVECTION SURROUNDING A DEFINED EYE WITH A
LARGE BANDING FEATURE DRAPED ACROSS THE NORTHERN SEMI-CIRCLE. THERE
IS HIGH CONFIDENCE IN THE INITIAL POSITION BASED ON THE EYE FEATURE
SEEN IN THE AFOREMENTIONED SATELLITE IMAGERY. THE INITIAL INTENSITY
HAS BEEN MAINTAINED AT 125 KNOTS BASED ON THE HIGH END DVORAK
CURRENT INTENSITY ESTIMATES THAT RANGE FROM 127 TO 120 KNOTS. UPPER-
LEVEL ANALYSIS INDICATES TY 07E REMAINS IN A FAVORABLE ENVIRONMENT
WITH LOW TO MODERATE VERTICAL WIND SHEAR (VWS) AND EXCELLENT RADIAL
OUTFLOW, WHICH IS BEING ENHANCED BY A TROPICAL UPPER TROPOSPHERIC
TROUGH (TUTT) CELL TO THE NORTHWEST, AS EVIDENT IN ANIMATED WATER
VAPOR IMAGERY. THE SYSTEM IS CURRENTLY TRACKING GENERALLY NORTHWARD
ALONG THE WESTERN PERIPHERY OF A DEEP-LAYERED RIDGE POSITIONED TO
THE EAST.
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TY 07E IS FORECAST TO TRACK NORTH-NORTHWESTWARD AND
ACCELERATE AS THE SYSTEM TRACKS UNDER THE STEERING INFLUENCE OF A
STRONG SUBTROPICAL RIDGE (STR) TO THE NORTHEAST AND A LARGE CYCLONIC
CIRCULATION, WHICH IS FORECAST TO EVOLVE OVER THE NEXT DAY TO THE
SOUTHWEST. THE SYSTEM IS EXPECTED TO GRADUALLY WEAKEN THROUGH TAU 72
AS VWS BEGINS TO INCREASE.
C. IN THE EXTENDED TAUS, THERE IS A HIGH DEGREE OF UNCERTAINTY IN
THE TRACK FORECAST DUE TO A COMPLEX STEERING ENVIRONMENT. A
MIDLATITUDE SHORTWAVE TROUGH IS FORECAST TO PROPAGATE RAPIDLY
EASTWARD WITHIN ZONAL MIDLATITUDE WESTERLIES AND POSSIBLY CREATE A
BREAK IN THE STR. DYNAMIC MODEL GUIDANCE INDICATES A WIDE VARIETY OF
SOLUTIONS RANGING FROM QUASI-STATIONARY MOVEMENT (GFS, JENS), A FAST
WESTWARD TRACK UNDER A DEVELOPING LOW-LEVEL HIGH (ECMWF), A WEAK
RE-CURVE (COAMPS-TC, EGRR) AND A SLOW NORTHWESTWARD TRACK (NVGM,
GFDN). DUE TO THE WEAK STEERING ENVIRONMENT PAST TAU 72, THE JTWC
TRACK FORECAST DEPICTS A SLOW WEST-NORTHWESTWARD TRACK IN THE
EXTENDED TAUS. TY 07E IS EXPECTED TO WEAKEN SIGNIFICANTLY AS IT
TRACKS NORTH OF 30N DUE TO COOLER SST RANGING FROM 24 TO 25C.
OVERALL, THERE IS LOW CONFIDENCE IN THE JTWC FORECAST TRACK.//

Genevieve will continue to weaken over the next couple of days. It formed from Eastern Pacific and made it all the way over to the Western Pacific. Very Cool :)

I know we've seen this before from Genevieve, but I think this may finally be the end. What a ride this has been!
