REMARKS:
141500Z POSITION NEAR 23.1S 156.2E.
TROPICAL CYCLONE (TC) 13P (LINDA), LOCATED APPROXIMATELY 334 NM
NORTH-NORTHEAST OF BRISBANE, AUSTRALIA, HAS TRACKED SOUTH-
SOUTHWESTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY DEPICTS A FULLY EXPOSED, DECAYING LOW
LEVEL CIRCULATION CENTER. ANIMATED WATER VAPOR IMAGERY SHOWS DRY AIR
ENTRAINMENT. A PARTIAL 141108Z ASCAT IMAGE SHOWS A NARROW REGION OF
35 KNOTS ON THE WESTERN SIDE OF THE CIRCULATION. ENVIRONMENTAL
ANALYSIS INDICATES THE SYSTEM IS IN AN AREA OF STRONG (35 TO 40
KNOTS) VERTICAL WIND SHEAR, DECENT POLEWARD OUTFLOW, AND 26C SST.
THEREFORE, TC 13P WILL WEAKEN BELOW 35 KNOTS BY TAU 12 AS THE
CYCLONE CONTINUES TO SLOWLY DRIFT TO THE SOUTHWEST. JTWC HAS HIGH
CONFIDENCE IN THE FORECAST TRACK. 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 141200Z IS 18 FEET.//
