REMARKS:
292100Z POSITION NEAR 27.2S 171.6E.
29JAN26. TROPICAL CYCLONE 18P (EIGHTEEN), LOCATED APPROXIMATELY
262 NM NORTHEAST OF KINGSTON IS., HAS TRACKED SOUTHWESTWARD AT 12
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTI-SPECTRAL IMAGERY (MSI)
DEPICTS TROPICAL CYCLONE 18P AS A FULLY EXPOSED AND SHALLOW VORTEX
BEING STEERED BY THE LOWER LEVEL EASTERLIES. IT IS COMPLETELY DEVOID
OF CONVECTION AND UPPER-LEVEL STRUCTURE AS IT TRACKS FARTHER
SOUTHWESTWARD INTO A HOSTILE ENVIRONMENT CHARACTERIZED BY HIGH
(30+ KTS) VERTICAL WIND SHEAR, DRY AIR, AND COOL (25-26 C) SEA
SURFACE TEMPERATURES. MODEL GUIDANCE IS IN STRONG AGREEMENT IN BOTH
TRACK AND INTENSITY, LENDING HIGH CONFIDENCE TO THE JTWC FORECAST.
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 291800Z IS 997 MB. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 291800Z IS 18 FEET.//
