REMARKS:
192100Z POSITION NEAR 25.2S 158.1W.
TROPICAL CYCLONE (TC) 20P (MIKE), LOCATED APPROXIMATELY 618 NM
SOUTHWEST OF PAPEETE, TAHITI, HAS TRACKED SOUTH-SOUTHEASTWARD
AT 21 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS DIMINISHING DEEP CONVECTION ASSOCIATED
WITH A DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC). A 191925Z METOP-
B MICROWAVE IMAGE REVEALS SHALLOW CONVECTIVE BANDING BROADLY
WRAPPING INTO THE LLCC. UPPER-LEVEL ANALYSIS INDICATES TC 20P IS
ENCOUNTERING THE MIDLATITUDE BAROCLINIC ZONE. THE SYSTEM WILL
SUCCUMB TO INCREASING VERTICAL WIND SHEAR AND DECREASING SEA SURFACE
TEMPERATURES AS IT COMPLETES EXTRATROPICAL TRANSITION OVER 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
191800Z IS 15 FEET.//
