REMARKS:
072100Z0 POSITION NEAR 19.2S2 116.0E8.
TROPICAL CYCLONE (TC) 26S (INIGO), LOCATED APPROXIMATELY 190 NM
WEST-NORTHWEST OF PORT HEDLAND, AUSTRALIA, HAS TRACKED SOUTHEASTWARD
AT 10 KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
071730Z8 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 55 AND 65
KNOTS. ANIMATED INFRARED IMAGERY REVEALS THAT THE DEEP CONVECTION
CONTINUES TO ACCELERATE TO THE SOUTHEAST, AHEAD OF THE LOW LEVEL
CIRCULATION CENTER, AS THE SYSTEM UNDERGOES EXTRATROPICAL TRANSITION
COINCIDENT WITH APPROACHING LANDFALL. TC 26S CONTINUES ON TRACK FOR
LANDFALL WEST OF PORT HEDLAND, AND SHOULD CONTINUE TO WEAKEN
SIGNIFICANTLY IN AN UNFAVORABLE UPPER-LEVEL ENVIRONMENT. THE SYSTEM
IS FORECAST TO DISSIPATE OVER LAND BY 24 HOURS. THE DYNAMIC AIDS ARE
CLUSTERED WITH RESPECT TO THE REMNANTS OF 26S AS THE SYSTEM TRACKS
OVER LAND. ONE CLUSTER CONSISTING OF BOM TLAPS, AFWA MM5 AND NCEP
AVIATION TRACK THE REMNANTS SOUTHWARD, PARALLEL TO THE WEST COAST OF
AUSTRALIA, WHILE NOGAPS, GFDN, BOM TCLAPS, AND UK MET OFFICE (EGRR)
MODELS TAKE THE SYSTEM FAR INLAND TO THE SOUTHEAST. THIS FORECAST IS
BASED ON A CONSENSUS OF THE LATTER CLUSTER AND PERSISTENCE. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 071800Z6 IS 18 FEET. NEXT WARNINGS AT
080300Z1, 080900Z7 AND 081500Z4. RELEASED BY LT INGRAM, USN.//
