220900Z POSITION NEAR 11.0S 85.9E. TROPICAL CYCLONE (TC) 15S (EMERAUDE), LOCATED APPROXIMATELY 846 NM EAST-SOUTHEAST OF DIEGO GARCIA, HAS TRACKED NORTHWESTWARD AT 01 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A BROAD, FULLY-EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH ISOLATED BURSTS OF DEEP CONVECTION DISPLACED OVER THE SOUTHWEST PERIPHERY OF THE LLCC. A 220328Z METOP-A 89 GHZ IMAGE REVEALS WEAKLY-DEFINED SHALLOW BANDING WRAPPING BROADLY INTO THE LLCC. RECENT SCATTEROMETER DATA SHOWS 25 TO 30 KNOT GRADIENT WINDS OVER THE SOUTHERN SEMI-CIRCLE WITH 20 TO 25 KNOTS ELSEWHERE. THE INITIAL INTENSITY IS ASSESSED AT 30 KNOTS BASED ON THE SCATTEROMETER DATA AS WELL AS DVORAK CURRENT INTENSITY ESTIMATES OF 2.0 (30 KNOTS). DYNAMIC MODEL GUIDANCE INDICATES THAT THE SYSTEM WILL TRACK GENERALLY WESTWARD THROUGH TAU 48 THEN WILL TURN SHARPLY POLEWARD. OVERALL, ENVIRONMENTAL CONDITIONS ARE FORECAST TO REMAIN MARGINALLY FAVORABLE UNTIL TAU 72 WHEN POLEWARD OUTFLOW IS EXPECTED TO IMPROVE WITH THE APPROACH OF A DEEP SHORTWAVE TROUGH. THEREFORE, THERE IS POTENTIAL FOR THE SYSTEM TO REGENERATE NEAR TAU 72. 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 220600Z IS 10 FEET. JUSTIFICATION FOR RELOCATION: RELOCATED PREVIOUS WARNING LOCATION BASED ON MULTISPECTRAL SATELLITE IMAGERY.
