REMARKS:
260900Z7 POSITION NEAR 18.6S5 119.8E9.
TROPICAL CYCLONE (TC) 18S (FAY), LOCATED APPROXIMATELY
130 NM NORTHEAST OF PORT HEDLAND, AUSTRALIA, HAS TRACKED
SOUTHWEST AT 04 KNOTS OVER THE PAST 06 HOURS. THE WARNING
POSITION IS BASED ON 260530Z6 MULTISPECTRAL SATELLITE IMAGERY
AND 260600Z4 BROOME RADAR IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 90 AND 115
KNOTS. TC 18S IS FORECAST TO CONTINUE TO TRACK SOUTHWESTWARD
INTO A WEAKNESS IN THE MID LEVEL STEERING RIDGE TO THE SOUTH
OF THE SYSTEM. RECENT MICROWAVE IMAGERY DEPICTS A WEAK 10 NM
DIAMETER EYE. ANIMATED WATER VAPOR IMAGERY INDICATES CONTINUED
DRY AIR ENTRAINMENT AND REDUCED OUTFLOW ALOFT. TC 18S IS FORECAST
TO SLOWLY WEAKEN IN INTENSITY OVER THE FORECAST PERIOD AS TC 18S
INTERACTS WITH LAND. THE AVAILABLE DYNAMIC AIDS, CONSISTING OF
NOGAPS, GFDN, NCEP GFS, TCLAPS, AFWA MM5, AND EGRR ARE IN GOOD
AGREEMENT WITH THIS SCENARIO. THIS FORECAST IS BASED ON
PERSISTENCE AND A BLEND OF THE AVAILABLE AIDS. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 260600Z4 IS 20 FEET. NEXT WARNINGS AT 262100Z1 AND
270900Z8. REFER TO TROPICAL CYCLONE  20S (OSCAR) WARNINGS
(WTXS32 PGTW) FOR TWELVE-HOURLY UPDATES.//
