Tropical Cyclone CLAUDIA : JTWC Advisories
Season 2001-2002 Summaries (Operational Data): [AU] [SIO] [SPAC] [SH]

RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 19.0S0 156.0E2 TO 23.8S3
156.9E1 WITHIN THE NEXT 03 TO 24 HOURS. AVAILABLE DATA DOES NOT
JUSTIFY ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS
TIME. WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS.
METSAT IMAGERY AT 110230Z7 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 19.3S3 156.1E3. THE SYSTEM IS MOVING SOUTHWARD AT
08 KNOTS.
2. REMARKS:
ANIMATED VISIBLE SATELLITE IMAGERY DEPICTS A WELL-DEFINED,
PARTIALLY-EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH DEEP
CONVECTION DEVELOPING OVER THE LLCC. A 102126Z2 SPECIAL SENSOR
MICROWAVE IMAGER PASS DEPICTED A CURVED CONVECTIVE BAND SOUTHWEST TO
WEST OF THE LLCC, AS WELL AS WEAK CONVECTIVE BANDING DEVELOPING EAST
TO SOUTH. A 101958Z4 QUIKSCAT PASS DEPICTED A WELL-DEFINED LLCC WITH
25-30 KNOT WINDS. THE UW-CIMSS ANALYSIS SHOWS LIGHT VERTICAL WIND
SHEAR, AND ANIMATED WATER VAPOR IMAGERY DEPICTS GOOD OUTFLOW OVER
THE LLCC. MAXIMUM SUSTAINED WINDS ARE ESTIMATED AT 25 TO 30 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. THE
POTENTIAL FOR DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY

TROPICAL CYCLONE (TC) 14P (CLAUDIA), LOCATED APPROXIMATELY 450 NM
NORTH-NORTHEAST OF BRISBANE, AUSTRALIA, HAS DEVELOPED QUICKLY OVER
THE PAST 12 HOURS. TC 14P HAS TRACKED SOUTH-SOUTHEASTWARD AT 14
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
110530Z0 VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON CURRENT SATELLITE INTENSITY ESTIMATES OF 35
AND 45 KNOTS (BRISBANE). ANIMATED SATELLITE IMAGERY DEPICTS A
RAPIDLY DEVELOPING SYSTEM WITH GOOD OUTFLOW OVER ALL QUADRANTS. A
110020Z4 TROPICAL RAINFALL MEASURING MISSION DEPICTED CONVECTIVE
BANDING WRAPPING INTO THE SYSTEM CENTER. THE UW-CIMSS ANALYSIS SHOWS
LIGHT VERTICAL WIND SHEAR.  TC 14P IS UNDER THE STEERING INFLUENCE
OF THE LOW TO MID-LEVEL RIDGE EAST OF THE SYSTEM AND THE TROUGH TO
THE SOUTHWEST. THEREFORE, TC 14P IS EXPECTED TO TRACK SOUTH TO
SOUTH-SOUTHEASTWARD THROUGH THE PERIOD. TC 14P IS EXPECTED TO
INTENSIFY AT A CLIMATOLOGICAL RATE UNDER A FAVORABLE ENVIRONMENT.
THE AVAILABLE DYNAMIC AIDS WERE LIMITED WITH NOGAPS INDICATING A
SOUTHWARD TRACK THROUGH 30 HOURS, THEN ERRONEOUSLY NORTHEASTWARD
AFTERWARDS. OUR FORECAST IS BASED ON PERSISTENCE, NOGAPS THROUGH 24
HOURS, THE MEDIUM BETA ADVECTION MODEL, AND THE CLIMATOLOGICAL AIDS.

REMARKS:
121500Z9 POSITION NEAR 25.3S0 162.6E5.
TROPICAL CYCLONE (TC) 14P (CLAUDIA), LOCATED APPROXIMATELY 295 NM
SOUTHWEST OF NOUMEA, NEW CALEDONIA, HAS TRACKED SOUTHEASTWARD AT
21 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
121130Z8 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 65 AND 77 KNOTS. THE 200
MB ANALYSIS INDICATES THE SYSTEM IS SOUTH OF THE UPPER LEVEL RIDGE
IN A REGION OF MODERATE VERTICAL WIND SHEAR AND MODERATE OUTFLOW
AIDED BY AN UPPER LEVEL TROUGH PASSING TO THE SOUTH. TC 14P IS UNDER
THE STEERING INFLUENCE OF THE MID-LEVEL RIDGE EAST-NORTHEAST OF THE
SYSTEM AND THE MID-LATITUDE TROUGH TO THE SOUTH. AS THE TROUGH
PASSES, THE STEERING WILL BE PROVIDED BY THE RIDGE TO THE EAST-
NORTHEAST WHICH WILL CONTINUE TO GUIDE TC 14P TO THE SOUTHEAST. TC
14P IS EXPECTED TO SLOWLY WEAKEN AS IT ENCOUNTERS COOLER SEA SURFACE
TEMPERATURES AND INCREASING VERTICAL WIND SHEAR ASSOCIATED WITH MID-
LATITUDE WESTERLIES. THE AVAILABLE DYNAMIC AIDS CONSIST OF NOGAPS,
GFDN, AVIATION, AND UKMET OFFICE GLOBAL (EGRR) MODELS. THE AIDS
AGREE IN A SOUTHEAST TRACK, BUT TWO AIDS DIFFER WITH REGARD TO
SYSTEM SPEED. GFDN FORECASTS THE SYSTEM TO EMBED INTO THE WESTERLY
FLOW OF THE PASSING TROUGH AND AS A RESULT, TAKES TC 14P RAPIDLY
DOWNSTREAM. EGRR ON THE OTHER HAND, WEAKENS THE SYSTEM AND SLOWLY
TRACKS THE SYSTEM TO THE EAST. OUR FORECAST IS BASED ON PERSISTENCE
AND A CONSENSUS OF ALL THE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 121200Z6 IS 13 FEET. NEXT WARNINGS AT 122100Z6, 130300Z7,

REMARKS:
132100Z7 POSITION NEAR 27.2S1  171.7E6.
TROPICAL CYCLONE (TC) 14P (CLAUDIA), LOCATED APPROXIMATELY 370 NM 
SOUTHEAST OF NOUMEA, NEW CALEDONIA, HAS TRACKED EASTWARD AT 11 KNOTS 
DURING THE PAST 12 HOURS. THE WARNING POSITION IS BASED ON 131730Z5 
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON 
SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35 KNOTS. ANIMATED 
INFRARED SATELLITE IMAGERY AND UPPER AIR ANALYSIS INDICATES THE 
SYSTEM HAS BEEN RAPIDLY SHEARED TO THE SOUTHEAST IN A HIGH VERTICAL 
WIND SHEAR ENVIRONMENT. THE SYSTEM HAS UNDERGONE EXTRATROPICAL 
TRANSITION. THE 200 MB ANALYSIS INDICATES THE SYSTEM IS WELL SOUTH 
OF THE UPPER LEVEL RIDGE. TC 14P IS UNDER THE STEERING INFLUENCE OF 
THE MID-LEVEL RIDGE EAST-NORTHEAST OF THE SYSTEM THAT WILL GUIDE THE 
SYSTEM TO THE EAST THROUGH THE FORECAST PERIOD. TC 14P IS EXPECTED 
TO CONTINUE TO RAPIDLY WEAKEN AS IT ENCOUNTERS INCREASING VERTICAL 
WIND SHEAR ASSOCIATED WITH THE MID-LATITUDE WESTERLIES AND COOLER 
SEA SURFACE TEMPERATURES. THE AVAILABLE DYNAMIC AIDS CONSISTING OF 
NOGAPS, GFDN, UKMET OFFICE GLOBAL (EGRR), AND BUREAU OF METEOROLOGY 
TCLAPS MODELS ARE IN GOOD AGREEMENT. OUR FORECAST IS BASED ON 
PERSISTENCE AND A BLEND OF ALL THE DYNAMIC AIDS. MAXIMUM SIGNIFICANT 
WAVE HEIGHT AT 131800Z3 IS 13 FEET. THIS IS THE FINAL WARNING ON 
THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVPACMETOCCEN).  
THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.
