REMARKS:
220900Z POSITION NEAR 39.5N 152.0E.
22SEP26. TROPICAL STORM 24W (DUJUAN), LOCATED APPROXIMATELY 424
NM EAST OF MISAWA, JAPAN, HAS TRACKED EAST-NORTHEASTWARD AT 24
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTI-SPECTRAL IMAGERY
DEPICTS TROPICAL STORM (TS) 24W (DUJUAN) WITH A VERY BROAD,
ELONGATED, AND FULLY EXPOSED LOW-LEVEL CIRCULATION CENTER. CONVECTION
IS HIGHLY SHEARED TO THE NORTHEAST AS THE SYSTEM FURTHER EMBEDS
ITSELF UNDER THE UPPER LEVEL JET. ENVIRONMENTAL ANALYSIS REVEALS A
HOSTILE ENVIRONMENT CHARACTERIZED BY COLD (23-24 C) SEA
SURFACE TEMPERATURES, EXTREME (60-65 KTS) VERTICAL WIND SHEAR,
EXTENSIVE DRY AIR ENTRAINMENT. 24W IS ASSESSED TO BE CURRENTLY
UNDERGOING EXTRATROPICAL TRANSITION (ETT), EXHIBITING MODERATE
TEMPERATURE ADVECTION INDUCED BY INTERACTION WITH THE JET. GLOBAL
DETERMINISTIC MODELS ARE IN STRONG AGREEMENT THAT 24W WILL COMPLETE
ETT WITHIN 12 HOURS AND CONTINUE TRACKING POLEWARD THROUGH THE
REMAINDER OF THE FORECAST PERIOD. 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. MINIMUM CENTRAL
PRESSURE AT 220600Z IS 975 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
220600Z IS 31 FEET.//
