21MAY23. TROPICAL CYCLONE 19S (FABIEN), LOCATED APPROXIMATELY 321
NM SOUTHWEST OF DIEGO GARCIA, HAS TRACKED SOUTHWARD AT 01 KNOTS
OVER THE PAST SIX HOURS. TC 19S FABIEN HAS RUN ITS COURSE, OVER
THE LAST SIX HOURS THE SYSTEM HAS WEAKENED CONSIDERABLY AS
INDICATED ON THE ENHANCED INFRARED IMAGERY (EIR). THE MOST
RECENT 211724Z METOP-C ASCAT INDICATED A TIGHTLY WRAPPED 20 KNOT
SYSTEM, WITH ONLY A COUPLE OF 25 KNOT FLAGS IN THE SOUTHWEST
QUADRANT NEAR THE ONLY SEMBLANCE OF CONVECTION. THE MOST RECENT
211720 METOP-C AMSU-B IMAGE REVEALED NO CONVECTION AROUND THE
LOW-LEVEL CIRCULATION CENTER. THE SYSTEM WAS UNDERGOING AN
ENORMOUS AMOUNT OF 25-30 KNOTS VERTICAL WIND SHEAR, WHICH
ERODED THE SMALL SYSTEMS INTEGRITY. FLARING CONVECTION NEAR
THE LLC WILL CONTINUE TO WAX AND WANE DIURNALLY AS THE REMNANTS
OF TC 19S MIGRATES TO THE SOUTH. 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 211800Z IS 14 FEET.//
