1. IMMEDIATE DELIVERY REQ TO AMEMBASSY SUVA
2. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT MORESBY AND AMEMBASSY
HONIARA SOLOMON ISLANDS
3. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
100 NM EITHER SIDE OF A LINE FROM 13.6S0 163.7E7 TO 18.4S3 164.5E6
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 15 TO 30 KNOTS. METSAT IMAGERY AT
132230Z1 INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 14.4S9
163.9E9. THE SYSTEM IS MOVING SOUTHWARD AT 04 KNOTS.
4. REMARKS: ANIMATED VISIBLE AND INFRARED IMAGERY SHOW INCREASED
DEEP CONVECTION AND BANDING FEATURES HAVE DEVELOPED AROUND THIS
SYSTEM. SYNOPTIC DATA ALSO SUPPORTS A GOOD LOW-LEVEL CIRCULATION
WITHIN THE CONVECTION. ANIMATION ALSO INDICATES THE SYSTEM HAS
TRACKED SOUTHWARD OVER THE PAST 6 HOURS. SYNOPTIC ANALYSIS SHOWS THIS
AREA IS NORTH OF A MID-LEVEL TROUGH AND JUST WEST OF AN UPPER-LEVEL
ANTICYCLONE. WATER VAPOR IMAGERY AND UW-CIMMS PRODUCTS INDICATE
OUTFLOW IS GOOD AND VERTICAL WINDSHEAR IS LIGHT. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS GOOD.

REMARKS:
150900Z5 POSITION NEAR 17.2S0  164.8E9.
TROPICAL CYCLONE 11P HAS TRACKED TOWARDS THE SOUTH AT 6 KNOTS DURING
THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 150530Z4 INFRARED
AND VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON A
COMBINATION OF SATELLITE CURRENT INTENSITY ESTIMATES OF 45 KNOTS
(KGWC AND PGTW) AND A 142307Z7 SCATTEROMETER PASS. TC 11P HAS
FLUCTUATED IN APPEARENCE DURING THE DAY DUE TO DIURNAL VARIATIONS.
THE SYSTEM HAS ONCE AGAIN BEGUN TO APPEAR MORE ORGANIZED AND
SYMMETRIC AROUND THE LOW LEVEL CIRCULATION AND THE UPPER LEVEL
OUTFLOW. TC 11P IS FORECAST TO CONTINUE MOVING SLOWLY TOWARDS THE
SOUTH UNDER THE WEAK STEERING INFLUENCE OF THE SUBTROPICAL RIDGE TO
THE EAST. THE SYSTEM IS FORECAST TO BEGIN TRACKING MORE SOUTH-
SOUTHEASTWARD DURING THE FIRST 24 HOURS, AND THEN THROUGHOUT THE
REMAINDER OF THE FORECAST PERIOD. TC 11P IS FORECAST TO CONTINUE TO
INTENSIFY NEAR CLIMATOLOGICALLY, WITH ONLY WEAK WESTWARD SHEAR
SLIGHTLY INHIBITING FURTHER INTENSIFICATION. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 150600Z2 IS 18 FEET. REFER TO WWPN30 PGFW FOR ADDITIONAL
SEA HEIGHT INFORMATION. NEXT WARNINGS AT 152100Z9 (DTG 151951Z2) AND

160530Z5 VISIBLE SATELLITE IMAGERY WITH CURRENT INTENSITY ESTIMATES
OF T4.5. ANIMATED VISIBLE SATELLITE IMAGERY INDICATES TC 11P (DANI)
HAS INTENSIFIED OVER THE PAST 06 HOURS AND HAS DEVELOPED A 6 NM

QUASI-STATIONARY THROUGHOUT THE NEXT 48 HOURS. CURRENTLY, TC 11P
(DANI) IS EMBEDDED IN A WEAK STEERING REGIME. THERE IS ONE MID-LEVEL
RIDGE TO ITS NORTHWEST AND ANOTHER WEAKER RIDGE TO ITS SOUTHEAST,
AND NEITHER RIDGE ARE PROVIDING A DOMINANT STEERING FORCE. IN
ADDITION, AN EXTRATROPICAL CYCLONE DUE SOUTH IN THE TASMAN SEA IS
BLOCKING TC 11P (DANI) FROM FALLING UNDER THE STEERING INFLUENCE OF
THE RIDGE TO ITS SOUTHEAST. THE CYCLONIC FORECAST PATH TRIES TO
BALANCE THE AFOREMENTIONED STEERING INFLUENCES WHILE ALLOWING THE
SOUTHEAST RIDGE TO BECOME DOMINANT BY THE 48 HOUR FORECAST POSITION.
TC 11P (DANI) IS EXPECTED TO CONTINUE INTENSIFYING THROUGHOUT THE

KNOTS AND IS PROBABLY MAKING A SMALL CYCLONIC LOOP. TC 11P (DANI)
HAS RAPIDLY INTENSIFIED DURING THE PAST 12 HOURS AND HAS A 12NM
DIAMETER EYE. WARNING POSITION AND INTENSITY ARE BASED ON A 161730Z8
INFRARED SATELLITE INTENSITY ESTIMATE OF T6.0 (115 KNOTS). STEERING
INFLUENCE FROM A STRENGTHENING MID-LEVEL RIDGE TO THE NORTHWEST OF
THIS SYSTEM IS RESPONSIBLE FOR THIS SYSTEM=S RECENT MOVEMENT.
TROPICAL CYCLONE 11P (DANI) IS FORECAST TO SLOW ITS FORWARD MOVEMENT
THEN TURN SOUTHWARD AS MID-LEVEL RIDGING TO ITS NORTHWEST EXTENDS
AND STRENGTHENS TO THE NORTHEAST OF THIS SYSTEM. IT IS ANTICIPATED
THAT TC 11P (DANI) WILL CONTINUE TO INTENSIFY SLOWLY THROUGH 24
HOURS THEN BEGIN TO WEAKEN SLOWLY AS WIND-GENERATED UPWELLING LOWERS

TROPICAL CYCLONE 11P (DANI) HAS MOVED NORTH-NORTHWESTWARD AT 06
KNOTS OVER THE PAST 6 HOURS AND IS MAKING A SMALL CYCLONIC LOOP WEST
OF VANUATU IN THE CORAL SEA. TC 11P (DANI) HAS LOST ITS EYE FOR THE

NORTH. WARNING POSITION AND INTENSITY ARE BASED ON A 170530Z6
VISIBLE SATELLITE IMAGE WITH A CURRENT INTENSITY ESTIMATE OF T5.5

PROVIDED THE STEERING FORCE OVER THE PAST 24 HOURS. HOWEVER,
TROPICAL CYCLONE 11P (DANI) IS FORECAST TO SLOW ITS FORWARD MOVEMENT
AS THE RIDGE TO THE NORTHWEST BUILDS TO THE NORTH OF THE SYSTEM. BY
THE 36 HOUR FORECAST POSITION, TC 11P (DANI) IS FORECAST TO MAKE A
U-TURN SOUTHWARD AS MID-LEVEL RIDGING TO THE NORTHEAST BUILDS SOUTH
AND TO THE EAST OF TC 11P (DANI) AND BECOMES THE DOMINANT STEERING
FORCE. TC 11P (DANI) WILL MAINTAIN INTENSITY FOR THE NEXT 24 HOURS
AND THEN NOGAPS ANALYSIS INDICATES TC 11P (DANI) WILL INTENSIFY

TROPICAL CYCLONE 11P (DANI) IS MOVING NORTHEASTWARD AND APPEARING TO
MAKE A SMALL CYCLONIC LOOP WEST OF VANUATU. ANIMATED INFRARED
SATELLITE IMAGERY INDICATES TC 11P (DANI) HAS A WELL DEVELOPED
CENTRAL DENSE OVERCAST FEATURE AND MAY REFORM AN EYE IN THE NEXT 03
TO 06 HOURS. WARNING POSITION AND INTENSITY ARE BASED ON 171730Z9
INFRARED SATELLITE INTENSITY ESTIMATES OF T5.5 (100 KNOTS). TC 11P
(DANI) CONTINUES TO BE STEERED BY THE MID LEVEL RIDGE TO ITS
NORTHWEST, HOWEVER THIS SYSTEM APPEARS TO BE SLOWING ITS FORWARD
MOVEMENT IN RESPONSE TO A DEVELOPING MID LEVEL RIDGE TO ITS
NORTHEAST. TROPICAL CYCLONE 11P (DANI) IS FORECAST TO COMPLETE THE
LOOP AND GRADUALLY ACCELERATE SOUTHWARD UNDER THE INFLUENCE OF THE
STRENGTHENING RIDGE TO ITS EAST. TC 11P (DANI) IS EXPECTED TO SLOWLY
INTENSIFY THROUGH 36 HOURS UNDER FAVORABLE ENVIRONMENTAL CONDITIONS,
THEN SLOWLY WEAKEN. AN ALTERNATE SCENARIO EXISTS IN WHICH TC 11P
(DANI) INTERACTS WITH A DEVELOPING LOW PRESSURE SYSTEM IN THE CORAL
SEA, CURRENTLY LOCATED NEAR 18S9 155E1. THIS WOULD RESULT IN TC 11P
(DANI) SLOWING BETWEEN 24 AND 36 HOURS AND WOULD TEMPORARILY CAP THE
INTENSITY OF TC 11P (DANI) AS THE LOW PRESSURE SYSTEM TO THE
SOUTHWEST ASSIMILATES INTO TC 11P (DANI)S CYCLONIC INFLOW PATTERN.
THE PROBABILITY OF THIS ALTERNATE SCENARIO IS LOW. MAXIMUM

REMARKS:
182100Z2 POSITION NEAR 13.9S3  166.8E1.
TROPICAL CYCLONE 11P (DANI) HAS TRACKED SOUTHEASTWARD AT 7 KNOTS
DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
181730Z7 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF T5.5 (100
KNOTS). TC 11P (DANI) HAS CONTINUED TO RESPOND TO THE INCREASED
STEERING FLOW OF THE SUBTROPICAL RIDGE TO ITS NORTHEAST. AS THIS
RIDGE CONTINUES TO BUILD TO THE EAST OF TC 11P (DANI), THE SYSTEM
IS FORECAST TO CONTINUE MOVING TOWARDS THE SOUTHEAST, AND
GRADUALLY MORE SOUTH-SOUTHEASTWARD THROUGHOUT THE FORECAST
PERIOD. A SLIGHT ACCELERATION OF THE SYSTEM IS ALSO FORECASTED.
TC 11P (DANI)IS EXPECTED TO INTENSIFY SLIGHTLY OVER THE NEXT 48
HOURS AS CONDITIONS REMAIN FAVORABLE FOR FURTHER DEVELOPMENT.
INTERACTION WITH NEARBY ISLANDS, HOWEVER, WILL HINDER RAPID
DEVELOPMENT OF THE SYSTEM. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
181800Z IS 26 FEET. REFER TO WWPN31 PGFW FOR ADDITIONAL SEA
HEIGHT INFORMATION. NEXT WARNINGS AT 190900Z9 (DTG 190751Z3) AND

TROPICAL CYCLONE 11P (DANI) HAS TRACKED TOWARDS THE SOUTH AT 8
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
191730Z1 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF T4.5 (77 KNOTS)
AND T5.0 (90 KNOTS). TC 11P (DANI) HAS MOVED BACK OUT OVER OPEN
WATERS NORTHEAST OF NEW CALEDONIA AFTER LOSING SOME INTENSITY
OVER LAND. THE SYSTEM IS FORECAST TO REMAIN ON A SOUTHWARD TRACK
UNDER THE STEERING INFLUENCE OF THE SUBTROPICAL RIDGE TO ITS
EAST. WEAK RIDGING AHEAD OF THE SYSTEM IS FORECAST TO SLIGHTLY
SLOW THE TRACK AND TURN IT JUST WEST OF SOUTH FROM THE 24 TO 36
HOUR PERIOD. AFTERWARDS, THE SYSTEM IS FORECAST TO REMAIN ON A
SOUTHWARD TRACK. TC 11P (DANI) IS FORECASTED TO SLOWLY INTENSIFY
THROUGHOUT THE 24 HOURS PERIOD. THE SYSTEM MAY THEN BEGIN TO BE
INFLUENCED BY A DEVELOPING SYSTEM TO ITS NORTHWEST IN THE SALOMON
SEA. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 191800Z IS 26 FEET. REFER
TO WWPN31 PGFW FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT

REMARKS:
212100Z6 POSITION NEAR 25.5S2 172.1E1.
TROPICAL CYCLONE 11P (DANI) IS MOVING SOUTHEASTWARD AT 15 KNOTS. A
MID-LEVEL RIDGE EAST OF THIS SYSTEM IS PROVIDING THE DOMINANT
ENVIRONMENTAL STEERING FLOW. TC 11P (DANI) CONTINUES TO WEAKEN AND
ANIMATED INFRARED SATELLITE IMAGERY INDICATES VERTICAL WIND SHEAR
FROM TC 13P TO THE WEST IS CONTRIBUTING TO THIS WEAKENING TREND. THE
WARNING POSITION AND INTENSITY ARE BASED ON A 211730Z4 INFRARED
SATELLITE INTENSITY ESTIMATE OF T4.5 (75 KNOTS) ADJUSTED BY 211140Z9
SCATTEROMETER DATA. TROPICAL CYCLONE 11P (DANI) IS FORECAST TRACK
SOUTHEASTWARD AROUND THE MID-LEVEL RIDGE AXIS. TC 11P (DANI) IS
EXPECTED TO WEAKEN SLOWLY THROUGH 36 HOURS UNDER THE INFLUENCE OF
VERTICAL WIND SHEAR FROM TC 13P AND THE EFFECT OF COOLER SEA SURFACE
TEMPERATURE. AFTER 36 HOURS IT IS ANTICIPATED TO MAINTAIN ITS
INTENSITY AS IT COMPLETES TRANSITION INTO AN EXTRATROPICAL SYSTEM
AND ACCELERATES TOWARD THE EAST-SOUTHEAST. WIND RADII HAVE BEEN
ADJUSTED BASED ON THE 211140Z9 SCATTEROMETER DATA. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 211800Z2 IS 24 FEET. NEXT WARNINGS AT
220900Z3 (DTG 220751Z7) AND 222100Z7 (DTG 221951Z0). REFER TO
TROPICAL CYCLONE 13P WARNINGS (WTPS32 PGTW) FOR TWELVE-HOURLY

REMARKS:
220900Z3 POSITION NEAR 27.7S6 174.4E6.
TROPICAL CYCLONE 11P (DANI) HAS TRACKED SOUTHEASTWARD AT 15 KNOTS
OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED UPON A 220530Z2
VISIBLE SATELLITE IMAGE. THE WARNING INTENSITY IS BASED UPON A
SATELLITE CURRENT INTENSITY ESTIMATE OF 60 KNOTS. ANIMATED WATER
VAPOR SATELLITE IMAGERY AND UW-CIMSS 220000Z4 SHEAR CHARTS INDICATE
TC 11P IS UNDERGOING MODERATE TO SEVERE VERTICAL WIND SHEAR. INDEED,
THE LATEST SATELLITE IMAGERY SHOWS A TOTALLY EXPOSED, WELL-DEFINED
LOW LEVEL CIRCULATION CENTER WITH THE DEEP CONVECTION 70 NM TO THE
NORTHEAST. TROPICAL CYCLONE 11P IS UNDER THE STEERING INFLUENCE OF
THE MID-LEVEL RIDGE TO ITS EAST AND IS FORECAST TO TRACK
SOUTHEASTWARD AROUND THE MID-LEVEL RIDGE AXIS AND BEGIN EXTRA-
TROPICAL TRANSITION BY THE 24 HOUR FORECAST POSITION. TROPICAL
CYCLONE 11P SHOULD CONTINUE TO WEAKEN THROUGHOUT THE FORECAST PERIOD
AS IT MOVES OVER COOLER SEA SURFACE TEMPERATURES AND AS THE VERTICAL
WIND SHEAR CONTINUES TO WEAKEN THE SYSTEM. WIND RADII HAVE BEEN
ADJUSTED BASED ON EARLIER SCATTEROMETER DATA. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 220600Z0 IS 24 FEET. NEXT WARNINGS AT 222100Z7 (DTG
221951Z0) AND 230900Z4 (DTG 230751Z8). REFER TO TROPICAL CYCLONE 13P
(OLINDA) WARNINGS (WTPS32 PGTW) FOR TWELVE-HOURLY UPDATES. REFER TO
