WTPS21 PGTW 20060211 08:00z
MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI/JTWC//
SUBJ/TROPICAL CYCLONE FORMATION ALERT/110751ZFEB2006//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
115 NM EITHER SIDE OF A LINE FROM 16.4S 174.2W TO 20.1S 174.2W
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
110600Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 16.6S
174.2W. THE SYSTEM IS MOVING SOUTHWARD AT 11 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 15.5S
174.4W, IS NOW LOCATED NEAR 16.6S 174.2W, APPROXIMATELY 245 NM
SOUTHWEST OF PAGO PAGO, AMERICAN SAMOA. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY AND A 080527Z AMSU-B SATELLITE PASS DEPICT AN
AREA OF DEEP CONVECTION PERSISTING NEAR A COMPLEX LOW LEVEL CIR-
CULATION CENTER (LLCC). AN EXPOSED SECONDARY CIRCULATION IS ALSO
EVIDENT APPROXIMATELY 100 NM TO THE SOUTH-SOUTHEAST OF THE DISTUR-
BANCE. UPPER LEVEL ANALYSIS DEPICTS LOW TO MODERATE VERTICAL WIND
SHEAR AND FAVORABLE EQUATORWARD DIFFLUENCE. WHILE CURRENT AND
FORECAST SOUNDINGS DEPICT AN UNFAVORABLE ENVIRONMENT POLEWARD OF
THE LLCC, THE SHORT-TERM UPPER LEVEL ENVIRONMENT IS FAVORABLE FOR
ADDITIONAL ORGANIZATION. MAXIMUM SUSTAINED WINDS ARE ESTIMATED AT
25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1000 MB. DUE TO CONTINUED CONVECTION NEAR THE LLCC AND FAVORABLE
OUTFLOW ALOFT, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED
BY 120800Z.//

REMARKS:
111500Z POSITION NEAR 17.4S 174.6W.
TROPICAL CYCLONE (TC) 11P (NONAME), LOCATED APPROXIMATELY 275 NM 
SOUTHWEST OF PAGO PAGO, AMERICAN SAMOA, HAS TRACKED SOUTH-SOUTHWESTWARD
AT 08 KNOTS OVER THE PAST SIX HOURS. THE CYCLONE IS TRACKING POLEWARD
WHILE ON THE WESTERN PERIPHERY OF A LOW- TO MID-LEVEL STEERING RIDGE
TO THE EAST. THE SYSTEM IS EXPECTED TO CURVE TOWARD THE SOUTHEAST
BETWEEN 36 AND 72 HOURS AS THE STEERING RIDGE RE-ORIENTS TO THE NORTH
AND EAST OF THE STORM. TC 11P IS EXPECTED TO INTENSIFY OVER THE NEXT
36 HOURS AS IT ENTERS A LOW SHEAR ENVIRONMENT AND MAINTAINS FAVORABLE
EQUATORWARD OUTFLOW. HOWEVER, A REGION OF DRIER AND MORE STABLE AIR
POLEWARD OF TC 11P WILL LIMIT THE RATE OF INTENSIFICATION. THIS WARNING
SUPERSEDES AND CANCELS REF A, NAVPACMETOCCEN 110751Z FEB 06 TROPICAL

HEIGHT AT 111200Z IS 10 FEET. NEXT WARNINGS AT 112100Z, 120300Z, 120900Z

REMARKS:
120900Z POSITION NEAR 18.6S 176.4W.
TROPICAL CYCLONE (TC) 11P (VAIANU), LOCATED APPROXIMATELY 300 NM EAST
OF SUVA, FIJI, HAS TRACKED SOUTHWESTWARD AT 05 KNOTS OVER THE PAST
SIX HOURS. TC 11P INTENSIFIED OVER THE LAST 12 HOURS AS CONVECTION
HAS CONSOLIDATED AROUND THE LOW LEVEL CIRCULATION CENTER. THE
CYCLONE WILL TRACK POLEWARD THROUGHOUT THE FORECAST PERIOD ALONG THE
WESTERN PERIPHERY OF A MID-LEVEL STEERING RIDGE TO THE EAST. ADDITIONAL
INTENSIFICATION IS LIKELY AS THE SYSTEM IS FORECAST TO REMAIN IN A LOW
VERTICAL WIND SHEAR ENVIRONMENT WITH GOOD EQUATORWARD OUTFLOW ALOFT.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 120600Z IS 21 FEET. NEXT WARNINGS
AT 122100Z AND 130900Z.//

REMARKS:
130900Z POSITION NEAR 21.3S 176.7W.
TROPICAL CYCLONE (TC) 11P (VAIANU), LOCATED APPROXIMATELY 325 NM
EAST-SOUTHEAST OF SUVA, FIJI, HAS TRACKED SOUTHWARD AT 10 KNOTS
OVER THE PAST SIX HOURS. TC 11P WILL TRACK POLEWARD THROUGHOUT THE
FORECAST PERIOD AS A MID-LEVEL RIDGE TO THE EAST REMAINS THE PRIMARY
STEERING MECHANISM. ALTHOUGH THE CYCLONE HAS INTENSIFIED OVER THE
PAST SEVERAL HOURS, RECENT ANIMATED WATER VAPOR IMAGERY REVEALS
A SUPPRESSION OF STORM OUTFLOW IN THE WESTERN QUADRANTS. UPPER LEVEL
ANALYSIS DEPICTS AN IMPINGING TROUGH AND DEVELOPING LOW JUST TO THE
WEST OF TC 11P. THE STORM SHOULD BEGIN TO WEAKEN WITHIN 24 HOURS DUE
TO DETERIORATING UPPER LEVEL OUTFLOW, INCREASING VERTICAL WIND SHEAR,
AND INCREASING ATMOSPHERIC STABILITY. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 130600Z IS 28 FEET. NEXT WARNINGS AT 132100Z AND 140900Z.//

TROPICAL CYCLONE (TC) 11P (VAIANU), LOCATED APPROXIMATELY 365 NM
SOUTHEAST OF SUVA, FIJI, HAS TRACKED SOUTHWARD AT 06 KNOTS
OVER THE PAST SIX HOURS. TC 11P WILL CONTINUE TO TRACK POLEWARD
ALONG THE SOUTHWESTERN PERIPHERY OF A HIGH AMPLITUDE STEERING RIDGE
CENTERED NORTHEAST OF THE SYSTEM. UPPER LEVEL ANALYSIS AND WATER
VAPOR IMAGERY REVEALS CONTINUED SUPPRESSION OF STORM OUTFLOW IN THE
WESTERN QUADRANTS DUE TO AN IMPINGING UPPER LEVEL TROUGH. THE STORM
HAS MAINTAINED INTENSITY HOWEVER DUE TO DIURNAL INFLUENCE AND GOOD
DIVERGENCE ALOFT CREATED BY AN UPPER LEVEL ANTICYCLONE CENTERED
NORTHWEST OF TC 11P. THE STORM WILL BEGIN TO WEAKEN NEAR TAU 24
DUE TO INCREASING VERTICAL WIND SHEAR, AND DECREASING SEA SURFACE
TEMPERATURES. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 131800Z IS 32 FEET.

140900Z POSITION NEAR 23.7S 175.2W.
TROPICAL CYCLONE (TC) 11P (VAIANU), LOCATED APPROXIMATELY 465 NM
SOUTHEAST OF SUVA, FIJI, HAS TRACKED SOUTHEASTWARD AT 09 KNOTS
OVER THE PAST SIX HOURS. THE SYSTEM WILL CONTINUE TO TRACK TO THE
SOUTHEAST UNDER THE INFLUENCE OF A SUBTROPICAL RIDGE TO THE NORTH-
EAST. INCREASED VERTICAL WIND SHEAR PAST TAU 12 WILL RESULT IN A
SLOW WEAKENING TREND THROUGHOUT THE FORECAST PERIOD. MAXIMUM SIG-
NIFICANT WAVE HEIGHT AT 140600Z IS 30 FEET. NEXT WARNINGS AT
142100Z AND 150900Z.//
