Tropical Cyclone Dominic 
WTXS21 PGTW 20090125 03:30z
MSGID/GENADMIN/NAVMARFCSTCEN PEARL HARBOR HI/JTWC//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
095 NM EITHER SIDE OF A LINE FROM 18.5S 119.1E TO 19.9S 114.9E
WITHIN THE NEXT 06 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 27 TO 32 KNOTS. METSAT IM-
AGERY AT 242330Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 18.6S 118.8E. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 14
KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 18.0S
114.9E, IS NOW LOCATED NEAR 18.6S 118.8E, APPROXIMATELY 340 NM
NORTHEAST OF LEARMONTH, AUSTRALIA. ANIMATED WATER VAPOR IMAGERY
SHOWS AN AREA OF DEEP CONVECTION WITH GOOD EQUATORWARD OUTFLOW
AND A DEVELOPING POLAR OUTFLOW CHANNEL OFF-SHORE OF PORT HEDLAND,
AUSTRALIA. A RECENT WEATHER RADAR COMPOSITE REFLECTIVITY LOOP
FROM PORT HEDLAND INDICATES A WELL FORMED LOW LEVEL CIRCULATION
CENTER (LLCC) WITH TIGHT CONVECTIVE BANDING WRAPPING INTO THE
CENTER. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS IN AN AREA OF
FAVORABLE VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 27 TO 32 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1002 MB. DUE TO THE RAPID DEVELOPMENT OF THE LLCC, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
260330Z.

REMARKS:
251500Z POSITION NEAR 19.4S 116.6E.
TC 10S (TEN), LOCATED APPROXIMATELY 235 NM NORTHEAST OF LEARMONTH,
AUSTRALIA HAS MOVED WEST-SOUTHWESTWARD AT 10 KNOTS OVER THE PAST O6
HOURS. ANIMATED WATER VAPOR IMAGERY SHOWS VERY GOOD WESTWARD OUTFLOW
OVER CONVECTIVE BANDS THAT HAVE WRAPPED TIGHTER INTO THE LOW LEVEL
CIRCULATION CENTER (LLCC). RADAR COMPOSITE REFLECTIVITY LOOP FROM
DAMPIER, AUSTRALIA DEPICTS A DISCERNIBLE LLCC SURROUNDED BY LIGHT TO
MODERATE RAINBANDS. CURRENT CENTRAL WIND SPEED IS BASED FROM SATEL-
LITE INTENSITY ESTIMATES FROM PGTW ANS APRF AND EXTRAPOLATED FROM
NEARBY SURFACE OBSERVATIONS. POSITION IS BASED ON SATELLITE AND RADAR
IMAGERY ANIMATIONS WITH GOOD CONFIDENCE. ENVIRONMENTAL ANALY-
SIS INDICATES THE CYCLONE IS IN AN AREA FAVORABLE FOR FURTHER DEVE-
LOPMENT WITH WARM SEA SURFACE TEMPERATURES, LIGHT VERTICAL WIND SHEAR
AND GOOD DIFFLUENCE ALOFT. THE SYSTEM IS TRACKING ALONG THE
NORTHWESTERN PERIPHERY OF A SUBTROPICAL RIDGE STRETCHED ALONG
SOUTHERN AUSTRALIA. BY TAU 48, MODEL GUIDANCE INDICATES A TROUGH TO
THE WEST OF THE LLCC IS EXPECTED TO DIG TO THE SOUTHEAST CAUSING TC
10S TO RETROGRADE AND REVERSE ITS MOTION TOWARDS THE EAST. THIS

REMARKS:
260300Z POSITION NEAR 19.6S 116.0E.
TC 10S (TEN), LOCATED APPROXIMATELY 200 NM NORTHEAST OF LEARMONTH, 
AUSTRALIA HAS MOVED SOUTHWESTWARD AT 06 KNOTS OVER THE PAST O6
HOURS. ANIMATED WATER VAPOR IMAGERY SHOWS HEALTHY EQUATORWARD AND 
POLEWARD OUTFLOW CHANNELS. THE RADAR COMPOSITE REFLECTIVITY 
LOOP FROM DAMPIER, AUSTRALIA DEPICTS A LOW LEVEL CIRCULATION CENTER 
(LLCC) WITH WELL DEFINED CONVECTIVE BANDING WRAPPING INTO THE LLCC 
FROM THE SOUTH. A 252237Z SSMI MICROWAVE IMAGE DEPICTS A WELL 
DEFINED CONVECTIVE BAND WRAPPING AROUND THE NORTHERN SEMICIRCLE OF 
THE SYSTEM AND INTO THE SOUTHERN SIDE OF THE LLCC. CURRENT CENTRAL 
WIND SPEED IS BASED ON SATELLITE INTENSITY ESTIMATES FROM PGTW AND 
APRF, OBSERVATIONS FROM BARROW ISLAND AND A 252240Z QUIKSCAT IMAGE. 
POSITION IS BASED ON ANIMATED INFRARED SATELLITE IMAGERY. THE SYSTEM 
REMAINS IN AN ENVIRONMENT FAVORABLE FOR CONTINUED DEVELOPMENT WITH 
LOW VERTICAL WIND SHEAR AND HIGH SEA SURFACE TEMPURATURES. AS THE 
SYSTEM MOVES SOUTHWARD TOWARD THE NORTHWEST COAST OF AUSTRALIA IT 
WILL BECOME INCREASINGLY AFFECTED BY FRICTION AND WILL ENTRAIN DRY 
AIR FROM THE SOUTH. AT TAU 24 AN APPROACHING MID-LATITUDE TROUGH 
WILL WEAKEN THE STEERING ENVIRONMENT CAUSING THE SYSTEM TO SLOW AND 
TRACK SOUTHWESTWARD ALONG THE WESTERN PERIPHERY OF THE SUBTROPICAL 
RIDGE OVER SOUTHERN AUSTRALIA. BY TAU 48 THE SYSTEM IS EXPECTED TO 
BE OVER LAND AND DISSIPATING.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 260000Z IS 10 FEET.
