TROPICAL CYCLONE (TC) 21P, LOCATED APPROXIMATELY 320 NM WEST-
SOUTHWEST OF HONIARA, SOLOMON ISLANDS, HAS TRACKED NORTH-
NORTHWESTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A FULLY-EXPOSED,
WEAKENING LOW-LEVEL CIRCULATION CENTER (LLCC) WITH RAPIDLY
DECAYING DEEP CONVECTION SHEARED SOUTHEAST OF THE SYSTEM
A 292323Z ASCAT IMAGE INDICATES NUMEROUS 20-25 KNOT
WINDS WITH AN ISOLATED 30 KNOT WIND OVER THE WEST QUADRANT.
THE ASCAT DATA AS WELL AS THE LATEST DVORAK ESTIMATES OF
25-30 KNOTS FROM PGTW AND KNES SUPPORT THE INITIAL INTENSITY
ASSESSMENT OF 30 KNOTS. MSI AND MICROWAVE IMAGERY SHOW THAT
THE LOW-LEVEL CIRCULATION CENTER (LLCC) DECOUPLED FROM THE
DEEP CONVECTION APPROXIMATELY 12 HOURS AGO AND BEGAN TO
TRACK EQUATORWARD UNDER THE STEERING INFLUENCE OF THE LOW-
LEVEL SOUTHERLY FLOW ASSOCIATED WITH THE STRENGTHENING
SUBTROPICAL RIDGE POSITION OVER THE CORAL SEA. 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
300000Z IS 10 FEET.//
