REMARKS:
100300Z POSITION NEAR 16.9S 111.9E.
TROPICAL CYCLONE 23S (WALLACE), LOCATED APPROXIMATELY 344 NM
NORTH-NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED WESTWARD AT
06 KNOTS OVER THE PAST SIX HOURS. THE FIRST FEW FRAMES OF ANIMATED
MULTI-SPECTRAL SATELLITE IMAGERY (MSI) REVEALED THAT THE LOW LEVEL
CIRCULATION CENTER (LLCC) HAS BECOME FULLY EXPOSED, WITH
DISORGANIZED CONVECTION DISPLACED TO THE SOUTHEAST. THE INITIAL
POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE MSI. THE
INITIAL INTENSITY WAS ASSESSED AT 35 KNOTS BASED ON THE PGTW DATA-T
OF T2.5 AND T2.5 CURRENT INTENSITY VALUES FROM KNES AND APRF.
VERTICAL WIND SHEAR HAS INCREASED TO 20-25 KNOTS, AND IS EXPECTED TO
CONTINUE INCREASING OVER THE NEXT 12-24 HOURS TO 35 KNOTS OR HIGHER.
DUE TO THE INCREASINGLY UNFAVORABLE SHEAR, TC 23S IS EXPECTED TO
DISSIPATE OVER THE NEXT 12 TO 24 HOURS AS IT TRACKS WEST-
SOUTHWESTWARD. 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 100000Z
IS 13 FEET.//
