REMARKS:
192100Z POSITION NEAR 36.5S 168.1E.
TROPICAL CYCLONE (TC) 09P (GITA), LOCATED APPROXIMATELY 501 NM
NORTHWEST OF WELLINGTON, NEW ZEALAND, HAS TRACKED SOUTHEASTWARD AT
28 KNOTS OVER THE PAST SIX HOURS. THE FIRST FEW FRAMES OF MULTI-
SPECTRAL SATELLITE IMAGERY DEPICT A RAGGED AND ELONGATED LOW LEVEL
CIRCULATION CENTER (LLCC) WITH DEEP CONVECTION DISPLACED WELL TO THE
SOUTH DUE TO STRONG NORTHWESTERLY VERTICAL WIND SHEAR (VWS). GITA IS
NOW ASSESSED AS FULLY EXTRA-TROPICAL. DUE TO A LACK OF RECENT
MICROWAVE IMAGERY AND THE ASYMMETRIC LLCC STRUCTURE, THERE IS LOW
CONFIDENCE IN THE INITIAL POSITION. DESPITE THE VWS AND LOSS OF DEEP
CONVECTION, ROBUST POLEWARD OUTFLOW AND INTERACTION WITH THE MID-
LATITUDE JET HAS HELPED MAINTAIN THE STRONG CORE WINDS DURING THE
EXTRA-TROPICAL TRANSITION. THE INITIAL INTENSITY IS ASSESSED AT 55
KNOTS BASED ON THE LARGE SWATH OF 50-55 KNOT WINDS IN A 191125Z
ASCAT PASS. TC 09P IS EXPECTED TO CONTINUE TRACKING SOUTHEASTWARD
UNDER THE STEERING INFLUENCE OF A DEEP-LAYER SUB-TROPICAL RIDGE TO
THE EAST, WITH A VERY GRADUAL DISSIPATION TREND. 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 191800Z IS 22 FEET.
