122100Z POSITION NEAR 29.6S 175.9E. TROPICAL CYCLONE 06P (ULA), LOCATED APPROXIMATELY 443 NM NORTH OF AUCKLAND, NEW ZEALAND, HAS TRACKED EAST-SOUTHEASTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED AND MULTISPECTRAL SATELLITE IMAGERY SHOW A DECOUPLING OF DEEP CONVECTION FROM THE LOW LEVEL CIRCULATION CENTER (LLCC) AS VERTICAL WIND SHEAR REMAINS AT HIGH LEVELS (40 TO 50 KNOTS). THE CURRENT INTENSITY OF 35 KNOTS IS BASED ON THE DVORAK ESTIMATE FROM PGTW AND IS SUPPORTED BY RECENT RSCAT AND ASCAT PASSES, INDICATING THE LLCC REMAINS SYMMETRICALLY ORGANIZED WITH WINDS RANGING FROM 35 TO 45 KNOTS. GIVEN THE RECENT WEAKENING TREND OBSERVED SINCE THE COLLECTION OF THE IMAGES, THERE IS GOOD CONFIDENCE IN THE INITIAL INTENSITY. INCREASING DRY AIR ENTRAINMENT, UNFAVORABLE SEA SURFACE TEMPERATURES AND VWS MAINTAINING HIGH LEVELS HAS STARTED THE EXTRA-TROPICAL TRANSITION (ETT) PROCESS. MODEL GUIDANCE AND ENVIRONMENTAL OBSERVATIONS INDICATE THE ETT PROCESS WILL BE COMPLETE WITHIN THE NEXT 12 HOURS. 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 121800Z IS 18 FEET.
