MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT 180851ZDEC2003//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 125 NM RADIUS OF 9.9S8 135.3E2 WITHIN THE NEXT 12 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 180930Z1 INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 9.9S8 135.3E2. THE SYSTEM IS
MOVING SOUTH-SOUTHEASTWARD AT 04 KNOTS.
2. REMARKS:
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR
9.7S6 135.9E8 IS NOW LOCATED NEAR 9.9S8 135.3E2, APPROXIMATELY 310
NM EAST-NORTHEAST OF DARWIN, AUSTRALIA. ANIMATED ENHANCED WATER
VAPOR AND INFRARED SATELLITE IMAGERY REVEALS AN INCREASE IN CONVECTION
AROUND A WEAK LOW LEVEL CIRCULATION CENTER (LLCC). LATEST 200 MB
ANALYSIS DEPICTS WEAK VERTICAL SHEAR AND GOOD OUTFLOW. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED TO BE NEAR 1004 MB. BASED ON IMPROVED ORGANIZATION, THE POTENTIAL
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT
24 HOURS IS NOW GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 190900Z9.//

REMARKS:
182100Z2 POSITION NEAR  9.7S6 135.3E2.
TROPICAL CYCLONE (TC) 05P (DEBBIE), LOCATED APPROXIMATELY 310 NM
NORTHWEST OF DARWIN, AUSTRALIA HAS BEEN QUASI-STATIONARY OVER
THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON 181641Z1 AMSU
AND 181730Z0 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF
35 KNOTS. TC 05P IS EXPECTED TO REMAIN QUASI-STATIONARY OVER THE
NEXT 12 TO 24 HOURS AS ENHANCED EQUATORIAL WESTERLY WINDS BALANCE
THE INFLUENCE OF THE LOW-MID LEVEL RIDGE TO THE SOUTH-SOUTHWEST
OF THE SYSTEM. THE SYSTEM SHOULD START TO TRACK SOUTH-SOUTHEASTWARD AS
THE EQUATORIAL WESTERLIES WEAKEN AND A RIDGE BUILDS TO THE EAST. TC 05P
IS IN A FAVORABLE ENVIRONMENT OF WEAK VERTICAL SHEAR, HIGH SEA SURFACE
TEMPERATURES, AND MARGINAL OUTFLOW. THEREFORE, INTENSIFICATION AT A
CLIMATOLOGICAL RATE IS EXPECTED THROUGH THE PERIOD. THE AVAILABLE DYNAMIC
AIDS, CONSISTING OF UKMET (EGRR), NCEP GFS, NOGAPS, AND WBAR ARE IN FAIR
AGREEMENT WITH THIS SCENARIO. THIS FORECAST IS BASED ON PERSISTENCE AND A
BLEND OF THE AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
181800Z8 IS 08 FEET. THIS WARNING SUPERSEDES AND CANCELS REF A, NAVPACMETOCCEN

04 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED
ON 190530Z8 MULTISPECTRAL SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35, 45, AND
65 KNOTS. FOR THE INITIAL 12 HOURS, TC 05P IS EXPECTED TO SLOWLY
TRACK TOWARD THE SOUTHWEST ALONG THE WEST-NORTHWEST PERIPHERY
OF A WEAK LOW TO MID-LEVEL STEERING RIDGE TO THE EAST. AFTER TAU
24, TC 05P WILL START TO TRACK WEST-SOUTHWEST ALONG THE NORTHERN
PERIPHERY OF A STRONG RIDGE LOCATED OVER AUSTRALIA. TC 05P IS IN
A FAVORABLE ENVIRONMENT OF WEAK TO MODERATE VERTICAL SHEAR, HIGH
SEA SURFACE TEMPERATURES, AND GOOD OUTFLOW ALOFT. TC 05P IS EXPECTED
TO INTENSIFY AT A CLIMATOLOGICAL RATE THROUGH TAU 24. AFTER TAU 24,
TC 05P WILL MAINTAIN INTENSITY. AFTER TAU 36, TC 05P WILL BEGIN TO

TROPICAL CYCLONE (TC) 05P (DEBBIE), LOCATED APPROXIMATELY 220 NM
NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD
AT 03 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED
ON SYNOPTIC DATA. THE WARNING INTENSITY IS BASED ON SYNOPTIC AND
ESTIMATED SATELLITE CURRENT INTENSITY ESTIMATES OF 55 KNOTS. TC
05P IS EXPECTED TO SLOWLY TRACK TOWARD THE SOUTHWEST ALONG THE
WEST-NORTHWEST PERIPHERY OF A WEAK LOW TO MID-LEVEL STEERING RIDGE
TO THE EAST. AFTER 24 HOURS TC 05P WILL START TO TRACK WEST-
SOUTHWEST ALONG THE NORTHERN PERIPHERY OF A RIDGE LOCATED OVER
CENTRAL AUSTRALIA. TC 05P IS IN A FAVORABLE ENVIRONMENT OF WEAK TO
MODERATE VERTICAL SHEAR, HIGH SEA SURFACE TEMPERATURES, AND GOOD
OUTFLOW ALOFT. TC 05P IS EXPECTED TO INTENSIFY AT A CLIMATOLOGICAL
RATE THROUGH 24 HOURS. AFTERWARDS TC 05P WILL BEGIN TO INTERACT

THE AVAILABLE DYNAMIC AIDS, CONSISTING OF UKMET (EGRR), NCEP GFS,

REMARKS:
200900Z1 POSITION NEAR 11.4S6 133.7E4.
TROPICAL CYCLONE (TC) 05P (DEBBIE), LOCATED APPROXIMATELY 190 NM
EAST-NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT
04 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON
200530Z0 MULTISPECTRAL SATELLITE IMAGERY AND SYNOPTIC DATA. THE
WARNING INTENSITY IS BASED ON SYNOPTIC AND ESTIMATED SATELLITE
CURRENT INTENSITY ESTIMATES OF 55 AND 65 KNOTS. TC 05P IS ABOUT
TO MAKE LANDFALL NEAR GOULBURN ISLAND, AUSTRALIA. TC 05P IS
EXPECTED TO SLOWLY TRACK WEST-SOUTHWESTWARD ALONG THE NORTHERN
PERIPHERY OF A RIDGE LOCATED OVER CENTRAL AUSTRALIA AND WEAKEN
RAPIDLY OVER LAND. TC 05P HAS SOME POTENTIAL TO SURVIVE OVER
LAND AND RETURN OVER THE OPEN TROPICAL WATERS OF THE TIMOR SEA
WHERE IT WOULD REINTENSIFY. THE AVAILABLE DYNAMIC AIDS CONSISTING
OF UKMET (EGRR), NCEP GFS, NOGAPS, TCLAPS, TLAPS, AND WBAR MODELS
ARE IN FAIR AGREEMENT WITH THIS SCENARIO. THIS FORECAST IS BASED
ON PERSISTENCE AND A BLEND OF THE AVAILABLE DYNAMIC AIDS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 200600Z8 IS 16 FEET. NEXT WARNINGS AT
202100Z5 AND 210900Z2. REFER TO TROPICAL CYCLONE 03S (CELA)
