REMARKS:
030300Z6 POSITION 16.8S5  152.3E1
TROPICAL CYCLONE 12P HAS FORMED IN THE CORAL SEA AND IS
NOW DRIFTING SOUTHEASTWARD AT 03 KNOTS.  THE WARNING
POSITION IS BASED UPON 022330Z0 VISIBLE SATELLITE
IMAGERY.  THE WARNING INTENSITY IS BASED UPON A
COMBINATION OF A SURFACE OBSERVATION OF 31 KNOTS FROM
LIHOU REEF (WMO NUMBER 94296) AT 022200Z6 AND A SATELLITE
INTENSITY ESTIMATE OF 45 KNOTS.  THE SYSTEM IS CURRENTLY
IN WEAK STEERING FLOW AND IS FORECAST TO MOVE VERY SLOWLY
EAST-SOUTHEASTWARD FOR 24 HOURS, THEN MOVE GENERALLY
EASTWARD.  THE SYSTEM HAS JUST UNDERGONE A PERIOD OF
RAPID INTENSIFICATION.  HOWEVER, IT IS UNUSUAL FOR THESE
SYSTEMS TO CONTINUE RAPID INTENSIFICATION FOR LONGER THAN
24 HOURS, THEREFORE THE FORECAST CALLS FOR A SLOWER
INTENSIFICATION RATE THROUGH THE PERIOD.  MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 030000Z IS 13 FEET.  NEXT
WARNINGS AT 031500Z9 (DTG 031351Z3) AND 040300Z7 (DTG

REMARKS:
031500Z9 POSITION 16.0S7 152.4E2
LATEST ANIMATED INFRARED SATELLITE IMAGERY SHOWS THAT
TROPICAL CYCLONE 12P (KATRINA) HAS INTENSIFIED OVER THE
PAST 12 HOURS AND HAS REMAINED QUASI-STATIONARY
APPROXIMATELY 300NM OFF THE COAST OF AUSTRALIA. THE
WARNING POSITION AND INTENSITY ARE BASED ON
031130Z8 INFRARED SATELLITE IMAGERY AND SURROUNDING
SYNOPTIC DATA. ENHANCED INFRARED IMAGERY INDICATES THE
CLOUD TOPS HAVE BECOME COOLER AND THE CONVECTION HAS
INCREASED SLIGHTLY IN AREAL COVERAGE. TC 12P IS
FORECAST TO REMAIN QUASI-STATIONARY THROUGH THE FORECAST
AS IT DRIFTS SLOWLY TOWARDS THE EAST UNDER THE INFLUENCE
OF WEAK LOW TO MID-LEVEL WESTERLY FLOW. THE SYSTEM IS
FORECAST TO INTENSIFY AS IT REMAINS IN AN ENVIRONMENT
WITH LITTLE VERTICAL WIND SHEAR AND GOOD OUTFLOW ALOFT.
MAXIMUM SIGNIFICANT WAVE AT 031200Z6 IS 13 FEET. NEXT

REMARKS:
040300Z7 POSITION 15.5S1  153.6E5
TROPICAL CYCLONE 12P (KATRINA) IS MOVING EAST-
NORTHEASTWARD AT 04 KNOTS.  THE WARNING POSITION IS BASED
UPON 032330Z1 VISIBLE SATELLITE IMAGERY.  THE SYSTEM=S
INTENSIFICATION HAS HALTED OVER THE PAST 12 HOURS.  THIS
MAY BE DUE TO THE OUTFLOW ALOFT FROM TROPICAL CYCLONE 11P
(SUSAN) INTERRUPTING THE UPPER LEVEL OUTFLOW OF TROPICAL
CYCLONE 12P (KATRINA).  THE WARNING INTENSITY IS BASED
UPON A SATELLITE INTENSITY ESTIMATE OF 45 KNOTS AND
CONTINUITY FROM THE PREVIOUS WARNING.  THE SYSTEM IS
FORECAST TO ONLY INTENSIFY AT A VERY SLOW RATE DUE TO THE
PRESENCE OF TROPICAL CYCLONE 11P (SUSAN) TO ITS EAST.
THE FORECAST TRACK SHOULD CONTINUE IN AN EASTWARD
DIRECTION THROUGH THE FORECAST PERIOD.  THE TRACK SPEED
SHOULD SLOW NEAR THE END OF THE PERIOD DUE TO A WEAKNESS
DEVELOPING BETWEEN NEAR EQUATORIAL RIDGING TO THE NORTH
AND A NORTHWESTWARD EXTENSION OF THE SUBTROPICAL RIDGE.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 040000Z IS 13 FEET.

REMARKS:
100300Z4 POSITION 15.6S2  164.2E3
TROPICAL CYCLONE 12P (KATRINA) IS MOVING WESTWARD AT 4
KNOTS. OUR WARNING POSITION AND INTENSITY ARE BASED ON
092330Z7 VISIBLE SATELLITE IMAGERY SHOWING A 19 NM EYE.
THE SYSTEM HAS INTENSIFIED AND IS FORECAST TO CONTINUE
THIS TREND. TC12P HAS TURNED ABRUPTLY TO THE WEST AS A
RESULT OF A DEVELOPING AREA OF HIGH PRESSURE DIRECTLY TO
ITS SOUTH. THE CIRCULATION AROUND THIS HIGH IS EXPECTED
TO DOMINATE THE CYCLONE=S STEERING FLOW THROUGH THE
FORECAST PERIOD AND RESULT IN A VERY SLOW WESTWARD DRIFT.
THIS IS A CHANGE FROM OUR PREVIOUS FORECAST WHICH
DEPICTED CONTINUED MOTION TOWARD THE SOUTHEAST. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 100000Z1 IS 20 FEET. NEXT

IN THE CORAL SEA. STEERING FROM THE HIGH PRESSURE TO THE
SOUTH HAS WEAKENED. ANIMATED WATER VAPOR IMAGERY
INDICATES A SLIGHT STRENGTHENING OF THE RIDGING DIRECTLY
TO THE WEST OF THE SYSTEM. DOMINANT STEERING INFLUENCE IS
EXPECTED TO BE REGAINED BY THE SOUTHERN HIGH PRESSURE
AREA, WITH RESULTING NORTHWESTWARD TO WESTWARD MOVEMENT,
WITHIN 12 TO 24 HOURS. AFTERWARDS, SLIGHT INTENSIFICATION
IS FORECAST AS UPPER-LEVEL WIND SHEAR REDUCES. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 121200Z IS 19 FEET. NEXT

AT 12 KNOTS.  THE WARNING POSITION IS BASED UPON 131130Z9
ENHANCED INFRARED SATELLITE IMAGERY.  THE WARNING
INTENSITY IS BASED UPON A SATELLITE INTENSITY ESTIMATE OF

RIDGE.  THE SYSTEM SHOULD BECOME NEARLY QUASI-STATIONARY
BY THE 48 HOUR POSITION.  AS TROPICAL CYCLONE 12P
(KATRINA) NEARS THE WEAKNESS IN THE SUBTROPICAL RIDGE,
OUTFLOW ALOFT SHOULD IMPROVE.  THIS SHOULD ALLOW THE

SATELLITE IMAGERY SUPPLEMENTED BY 141939Z7 MICROWAVE DATA.
141939Z7 MICROWAVE DATA REVEALS AN EYE FORMING BENEATH THE CIRRUS
OVERCAST AT THE SYSTEM CENTER AND A SEPARATE SPIRAL BAND OF DEEP
CONVECTION TO THE NORTH. THE WARNING INTENSITY IS BASED ON VISIBLE
AND INFRARED SATELLITE INTENSITY ESTIMATES OF 77 KNOTS. ANIMATED
VISIBLE SATELLITE IMAGERY INDICATES THAT DEEP CONVECTION AROUND
THE SYSTEM CENTER HAS INCREASED IN AREAL EXTENT AND CLOUD TOP
TEMPERTURES HAVE COOLED. TROPICAL CYCLONE 12P (KATRINA) IS FORECAST
TO CONTINUE MOVING WESTWARD THROUGH 12 HOURS.  AFTER 12 HOURS THIS
SYSTEM IS EXPECTED TO TURN TOWARD THE WEST-SOUTHWEST AS AN
APPROACHING MID-LATITUDE TROUGH WEAKENS THE STEERING FLOW OF THE
SUBTROPICAL RIDGE. TROPICAL CYCLONE 12P (KATRINA) IS EXPECTED TO
INTENSIFY THROUGHOUT THE FORECAST PERIOD DUE TO FAVORABLE
ENVIRONMENTAL CONDITIONS AND A LACK OF VERTICAL WIND SHEAR OVER
THIS SYSTEM. WIND RADII WERE ADJUSTED FROM THE LAST WARNING BASED ON
ANIMATED VISIBLE SATELLITE IMAGERY AND 141939Z7 MICROWAVE IMAGER DATA

REMARKS:
171500Z4 POSITION 17.1S9  148.1E4
TROPICAL CYCLONE 12P (KATRINA) HAS TRACKED SOUTHWESTWARD AT
05 KNOTS OVER THE PAST 06 HOURS.  THE WARNING POSITION IS BASED
UPON 181130Z4 ENHANCED INFRARED SATELLITE IMAGERY.  DURING THE
PAST 12 HOURS, TROPICAL CYCLONE 12P (KATRINA) HAS SHOWN
EVIDENCE OF WEAKENING DUE TO MODERATE VERTICAL WIND SHEAR.  THE
WARNING INTENSITY IS BASED UPON A SATELLITE INTENSITY ESTIMATE
OF 65 KNOTS.  THE SYSTEM SHOULD CONTINUE TRACKING SOUTHWESTWARD
FOR THE NEXT 12 HOURS.  A MORE WEST-SOUTHWESTWARD TURN SHOULD
OCCUR BY THE 24 HOUR POSITION AND CONTINUE THROUGH THE
REMAINDER OF THE FORECAST PERIOD.  THIS IS DUE TO THE RE-
DEVELOPMENT OF THE SUBTROPICAL RIDGE SOUTH TO SOUTHEAST OF THE
SYSTEM. HOWEVER, THE MOVEMENT SHOULD BE SLOW DURING THE PERIOD
AS THE STEERING FLOW IS FORECAST TO WEAKEN WITH TIME. THERE IS
NO SIGNIFICANT CHANGE TO THE INTENSITY FORECAST. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 181200Z IS 21 FEET. NEXT WARNINGS AT
180300Z2 (DTG 180151Z6) AND 181500Z5 (DTG 181351Z9).//

REMARKS:
180300Z2 POSITION 16.7S4 148.1E4
TROPICAL CYCLONE 12P (KATRINA) HAS WEAKENED SLIGHTLY AND
REMAINED QUASI-STATIONARY OVER THE PAST 12 HOURS. THE
WARNING POSITION AND INTENSITY ARE BASED ON A COMBINATION
OF SURROUNDING SYNOPTIC DATA AND 172330Z6 SATELLITE
IMAGERY. CURRENT WIND RADII HAVE BEEN ADJUSTED BASED ON
SYNOPTIC REPORTS FROM HOLMES REEF (WMO 94289) AND
FLINDERS REEF (WMO 94290). ANIMATED VISIBLE SATELLITE
IMAGERY SHOWS TC 12P IS ENCOUNTERING STRONG SHEAR FROM
THE WEST. HOWEVER, OVER THE PAST 3 HOURS CONVECTION HAS
DEVELOPED CLOSE TO THE EXPOSED LOW-LEVEL CENTER WHICH
INDICATES THE WINDS FROM THE WEST HAVE WEAKENED. ANIMATED
WATER VAPOR IMAGERY SHOWS UPPER-LEVEL OUTFLOW TO THE
SOUTHEAST IS IMPROVING. THE FORECAST PHILOSOPHY REMAINS
SIMILAR AS TROPICAL CYCLONE 12P IS EXPECTED TO TRACK
TOWARDS THE WEST UNDER THE INFLUENCE OF ENVIRONMENTAL
EASTERLY FLOW. THE SYSTEM IS FORECAST TO INTENSIFY SLOWLY
THROUGH THE 36 HOUR PERIOD AS IT MOVES INTO AN AREA WITH
LESS VERTICAL WIND SHEAR. AT THE 48 HOUR PERIOD TC 12P IS
FORECAST TO WEAKEN AS IT INTERACTS WITH LAND. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 180000Z9 IS 23 FEET. NEXT
WARNINGS AT 181500Z5 (DTG 181351Z9) AND 190300Z3 (DTG

REMARKS:
181500Z5 POSITION 16.8S5  149.8E2
TROPICAL CYCLONE 12P (KATRINA) HAS BEEN TRACKING EASTWARD
AT 08 KNOTS DURING THE PAST 06 HOURS.  THIS IS A DISTINCT
CHANGE FROM THE PREVIOUS FORECAST TRACK, HENCE THE
RELOCATION.  NUMEROUS RADAR REPORTS FROM WMO NUMBER 94299,
SEVERAL MICROWAVE IMAGERY PASSES, AND SYNOPTIC DATA FROM WMO
NUMBERS 94299 AND 94289 ALL INDICATE THAT THE SYSTEM HAS
CHANGED FROM A SLOW WESTWARD COURSE TO AN EASTERLY ONE.  THE
WARNING POSITION IS BASED UPON A COMBINATION OF 181102Z3
ENHANCED INFRARED SATELLITE I IMAGERY, A 181000Z0 RADAR
OBSERVATION FROM WILLIS ISLAND (94299) AND SYNOPTIC
OBSERVATIONS FROM HOLMES REEF (94289) AND WILLIS ISLAND.
HOLMES REEF (94299) INDICATED 50 KNOT SUSTAINED WINDS AT
180300Z2 AND MICROWAVE IMAGERY INDICATES TROPICAL CYCLONE
(KATRINA) CONVECTION AND ORGANIZATION HAS INCREASED DURING
THIS TIME.  THE WARNING INTENSITY IS BASED UPON A
COMBINATION OF THESE OBSERVATIONS AND A SATELLITE INTENSITY
ESTIMATE OF 55 KNOTS.  CURRENTLY, TROPICAL CYCLONE 12P
(KATRINA) IS BEING STEERED BY NEAR EQUATORIAL RIDGING.  THE
NEAR EQUATORIAL RIDGING IS FORECAST TO WEAKEN WITHIN 24
HOURS RESULTING IN THE SYSTEM SLOWING DOWN.  IT SHOULD BEGIN
TURNING SOUTHWARD AND THEN SOUTHWESTWARD DUE TO A DEVELOPING
WEAKNESS IN THE SUBTROPICAL RIDGE LOCATED TO THE SOUTH. THE
SYSTEM SHOULD ONLY INTENSIFY SLIGHTLY DURING THE FORECAST
PERIOD.  MAXIMUM SIGNIFICANT WAVE HEIGHT AT 181200Z IS 23
FEET.  NEXT WARNINGS AT 190300Z3 (DTG 190151Z7) AND 191500Z6

SOUTHWARD TURN BY THE 12 HOUR POSITION AS A WEAKNESS IN
THE SUBTROPICAL RIDGE TO THE SOUTH IS FORECASTED TO
OCCUR.  THE SYSTEM SHOULD CONTINUE SOUTHWARD THROUGH THE
REMAINDER OF THE FORECAST PERIOD AS IT MOVES INTO THIS
WEAKNESS ALLOWING FOR SOME SLIGHT INTENSIFICATION.
