SUBJ/PROGNOSTIC REASONING FOR TYPHOON 25W (WIPHA) WARNING NR 21//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TYPHOON 25W (WIPHA), LOCATED APPROXIMATELY 345 NM SOUTH-SOUTHWEST
OF YOKOSUKA, JAPAN, HAS TRACKED NORTHEASTWARD AT 25 KNOTS OVER THE
PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS
THE SYSTEM CONTINUED TO ACCELERATE POLEWARD AND BECAME MORE
DISORGANIZED AND ELONGATED - PRIMARILY ALONG THE NORTHERN PERIPHERIES
- AS THE CYCLONE GOT EMBEDDED DEEPER INTO THE MID-LATITUDE
WESTERLIES. THE INITIAL POSITION IS BASED ON THE ABOVE ANIMATION AND
ON A 151043Z SSMIS MICROWAVE PASS WITH HIGH CONFIDENCE. THE INITIAL
INTENSITY IS ON THE LOW END OF DVORAK ESTIMATES FROM PGTW, KNES, AND
RJTD TO REFLECT THE WEAKENING TREND. UPPER LEVEL ANALYSIS INDICATES
THE SYSTEM HAS BEGUN A RAPID EXTRA-TROPICAL TRANSITION. THE CYCLONE
IS NOW TRACKING ALONG THE POLEWARD EDGE OF THE SUBTROPICAL RIDGE
ANCHORED TO THE EAST.
3. FORECAST REASONING.
A. THERE IS NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE
PREVIOUS PROGNOSTIC REASONING MESSAGE.
B. TYPHOON WIPHA WILL ACCELERATE FURTHER NORTHEASTWARD AHEAD
OF THE APPROACHING TROUGH TO THE NORTHWEST. IT WILL CONTINUE TO
WEAKEN DUE TO INCREASING VERTICAL WIND SHEAR, PASSAGE OVER COOLER
WATER AND IMMERSION DEEPER INTO THE COLD BAROCLINIC AIR MASS. THE
SYSTEM IS EXPECTED TO BECOME A STRONG COLD-CORE LOW BY TAU 12.
DETERMINISTIC AND ENSEMBLE MODEL GUIDANCE REMAIN IN VERY TIGHT
AGREEMENT THROUGHOUT THE FORECAST. THE FORECAST TRACK IS LAID
SLIGHTLY AHEAD OF THE MODEL CONSENSUS WITH HIGH CONFIDENCE. //

REMARKS:
152100Z POSITION NEAR 34.3N 140.4E.
TYPHOON 25W (WIPHA), LOCATED APPROXIMATELY 161 NM SOUTH-SOUTHWEST OF
YOKOSUKA, JAPAN, HAS TRACKED NORTHEASTWARD AT 30 KNOTS OVER THE PAST
SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS THE SYSTEM
CONTINUES TO ACCELERATE POLEWARD AND HAS BECOME MORE DISORGANIZED
AND ELONGATED, PRIMARILY ALONG THE NORTHERN PERIPHERY. ADDITIONALLY,
TRACK SPEEDS HAVE INCREASED AND THE CYCLONE HAS BECOME EMBEDDED
DEEPER INTO THE MID-LATITUDE WESTERLIES. THE INITIAL POSITION IS
BASED ON THE ABOVE ANIMATION AND RADAR FIXES FROM RJTD WITH HIGH
CONFIDENCE. THE INITIAL INTENSITY IS BASED ON CONGRUENT DVORAK
CURRENT INTENSITY ESTIMATES FROM PGTW, KNES, AND RJTD TO REFLECT THE
WEAKENING TREND. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS IN A
RAPID EXTRA-TROPICAL TRANSITION. THE CYCLONE IS NOW TRACKING ALONG
THE POLEWARD EDGE OF THE SUBTROPICAL RIDGE ANCHORED TO THE EAST.
TYPHOON WIPHA WILL ACCELERATE FURTHER NORTHEASTWARD AHEAD OF THE
APPROACHING TROUGH TO THE NORTHWEST. IT WILL CONTINUE TO WEAKEN DUE
TO INCREASING VERTICAL WIND SHEAR, TRACKING OVER COOLER WATER AND
IMMERSION DEEPER INTO THE COLD BAROCLINIC AIR MASS. THE SYSTEM IS
EXPECTED TO BECOME A STRONG COLD-CORE LOW BY TAU 12. THE FORECAST
TRACK IS LAID SLIGHTLY AHEAD OF THE MODEL CONSENSUS WITH HIGH
CONFIDENCE. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT
TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED
FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
151800Z IS 30 FEET.//
