1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 14.7S2 128.2E3 TO 14.8S3
122.9E4 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 20 TO 25 KNOTS.
METSAT IMAGERY AT 272330Z7 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 15.1S7 127.4E4. THE SYSTEM IS MOVING WEST-
NORTHWESTWARD AT 08 KNOTS.
2. REMARKS: THE AREA OF CONVECTION LOCATED OVER NORTHWESTERN
AUSTRALIA HAS CONTINUED TO PERSIST AND BECOME MORE ORGANIZED OVER
THE LAST 6 HOURS. ANIMATED SATELLITE IMAGERY INDICATES STRONG
CONVECTION LOCATED OVER THE TIMOR SEA. RECENT SYNOPTIC DATA AND
QUICKSCATT DATA INDICATE A LOOSELY DEFINED AND PARTIALLY EXPOSED LOW
LEVEL CIRCULATION CENTER (LLCC) LOCATED INLAND OVER THE KIMBERLY
PENINSULA. UW-CIMSS SATELLITE DERIVED WIND PRODUCTS INDICATE A
FAVORABLE UPPER LEVEL ENVIRONMENT FOR FURTHER DEVELOPMENT AS THE
LLCC CONTINUES MOVING TOWARD THE COAST. THE SYSTEM IS UNDER WEAK TO
MODERATE VERTICAL WIND SHEAR AND MODERATE SPEED DIVERGENCE ALOFT
NORTH OF THE SUBTROPICAL RIDGE AXIS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1004 MB. 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

TROPICAL CYCLONE (TC) 07S, LOCATED APPROXIMATELY 600NM
NORTHEAST OF LEARMONTH, AUSTRALIA HAS TRACKED WEST-SOUTHWEST AT 10
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS
BASED ON 290530Z9 INFRARED AND VISIBLE SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT ESTIMATES
OF 25 AND 30 KNOTS. ANIMATED INFRARED SATELLITE IMAGERY
SHOWS ORGANIZING CONVECTION ABOUT A POSSIBLE LOW LEVEL THE
CIRCULATION CENTER. UW-CIMSS ANALYSIS PRODUCT INDICATES THE
SYSTEM IS IN AN AREA OF WEAK VERTICAL WIND SHEAR WITH FAVORABLE
OUTFLOW ALOFT. THE SYSTEM IS EXPECT TO TRACK WESTWARD UNDER
THE STEERING INFLUENCE OF A MIDLEVEL RIDGE SOUTH OF THE SYSTEM.
AFTER THE 24HR PERIOD THE SYSTEM WILL TRACK SOUTHWESTWARD
RESPONDING TO A WEAKNESS IN THE MID LEVEL RIDGE. TC 07S IS
EXPECTED TO WEAKEN AS IT ENCOUNTERS LAND SHORTLY AFTER THE 48HR
PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 290600Z7 IS 9 FEET.
