REMARKS:
290300Z POSITION NEAR 16.9S 117.5E.
TROPICAL CYCLONE (TC) 08S (MELANIE), LOCATED APPROXIMATELY 225 NM
NORTH-NORTHWEST OF PORT HEDLAND, AUSTRALIA, HAS TRACKED SOUTH-
SOUTHWESTWARD AT 08 KNOTS OVER THE PAST 06 HOURS. THE INITIAL
POSITION IS BASED ON SATELLITE FIXES FROM PGTW AND APRF AND A
282319Z SSMI PASS. DVORAK T-NUMBERS OF 4.0/4.0 FROM PGTW AND
3.0/3.0 FROM APRF AND EVIDENCE OF A BANDING EYE FEATURE IN THE
282319Z SSMI PASS SUPPORT AN INITIAL INTENSITY ESTIMATE OF 55
KNOTS. TC 08S IS BEGINNING TO TURN WESTWARD AS DEEP SUBTROPICAL
RIDGING TO THE SOUTH EXERTS AN INCREASING INFLUENCE ON STORM
MOTION. THE WESTWARD COMPONENT OF STORM MOTION WILL CONTINUE TO
INCREASE AS THE SUBTROPICAL RIDGE BECOMES THE DOMINANT STEERING
MECHANISM THROUGH THE FORECAST PERIOD. THE PERIPHERAL FLOW ASSOCI-
ATED WITH AN UPPER LEVEL, SYNOPTIC-SCALE ANTICYCLONE CENTERED EAST
OF TC 08S CONTINUES TO IMPACT THE STORM BY INTRODUCING NORTHEAST-
ERLY VERTICAL WIND SHEAR. HOWEVER, GOOD POLEWARD OUTFLOW AND HIGH
OCEAN HEAT CONTENT SHOULD SUPPORT SLOW INTENSIFICATION DESPITE
THIS SHEAR. AFTER TAU 48, DECREASING POLEWARD OUTFLOW AND OCEAN
HEAT CONTENT WILL HAMPER FURTHER INTENSIFICATION OR PERHAPS INDUCE
SLIGHT WEAKENING. THE AVAILABLE OBJECTIVE AIDS ARE IN GOOD, GENERAL
AGREEMENT WITH BOTH THE TRACK AND INTENSITY FORECASTS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 290000Z IS 18 FEET. NEXT WARNINGS AT
290900Z, 291500Z, 292100Z AND 300300Z.//

Extremely cold cloud tops continue with Melanie. The eye has not poked through the CDO yet, but it can be seen easily in the vapor imagery:

I haven't seen that much white in a cyclone in quite a while.
