REMARKS:
220300Z POSITION NEAR 10.2N 153.7E.
22APR23. TROPICAL DEPRESSION (TD) 01W (SANVU), LOCATED APPROXIMATELY
576 NM EAST-SOUTHEAST OF ANDERSEN AFB, HAS TRACKED WESTWARD AT 08
KNOTS OVER THE PAST SIX HOURS. TD 01W HAS DE-COUPLED FROM THE AREA
OF DEEP CONVECTION OVER THE EASTERN PERIPHERY AND HAS RAPIDLY 
WEAKENED. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS LOW-LEVEL
CLOUD LINES WRAPPING AROUND A BROAD, WEAK LOW-LEVEL CIRCULATION
CENTER (LLCC) BUT REVEALS NO CLOSED LLCC. DEEP CONVECTION OVER THE
EASTERN PERIPHERY HAS PERSISTED DUE TO STRONG SOUTHERLY CONVERGENCE
BUT HAS DWINDLED OVER THE PAST SIX HOURS. A 212340Z ASCAT-C BULLSEYE
SHOWS A BROAD CENTER WITH 10-15 KNOT WINDS AND ISOLATED 25 KNOT WINDS
TO THE NORTHEAST. AN EARLIER ASCAT-B IMAGE INDICATED A PATCH OF 25-30
KNOT WINDS DISPLACED OVER 120NM TO THE EAST UNDER THE DEEP CONVECTION.
IN GENERAL, SATELLITE IMAGERY AND ASCAT DATA SUPPORT THE SIGNIFICANT
DECREASE IN THE INITIAL INTENSITY TO 25 KNOTS. THE POOR, RAGGED
STRUCTURE OF THE LLCC SUPPORTS THE DECISION TO FINAL WARN THE SYSTEM.
TD 01W IS EXPECTED TO TRACK WESTWARD TO WEST-NORTHWESTWARD OVER THE
NEXT 24 HOURS WITH DISSIPATION OCCURRING IN THE NEXT 12 HOURS. DUE
TO THE MARGINAL ENVIRONMENT SPECIFICALLY THE HIGH MID-LEVEL VERTICAL
WIND SHEAR AND DRY AIR ENTRAINMENT, TD 01W IS UNLIKELY TO REGENERATE.             
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 220000Z
IS 15 FEET.//
