SUBJ/TROPICAL CYCLONE FORMATION ALERT 051821Z FEB 05//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 170
NM EITHER SIDE OF A LINE FROM 12.3S6 139.3E6 TO 17.9S7 140.6E1 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 051430Z3 INDI-
CATES THAT A CIRCULATION CENTER IS LOCATED NEAR 13.6S0 140.0E5. THE
SYSTEM IS MOVING SOUTH-SOUTHWESTWARD AT 09 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 12.9S2
139.0E3 IS NOW LOCATED NEAR 13.6S0 140.0E5, APPROXIMATELY 125 NM
WEST-SOUTHWEST OF WEIPA, AUSTRALIA. RECENT ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY REVEALS A SIGNIFICANT INCREASE IN DEEP CONVECTION
ALONG THE SOUTHERN SEMICIRCLE, AND ENHANCED WATER VAPOR IMAGERY SHOWS
AN INCREASE IN POLEWARD OUTFLOW. A 050833Z9 QUIKSCAT PASS DEPICTS A
WELL DEFINED LOW LEVEL CIRCULATION CENTER (LLCC) WITH STRONG NORTHER-
LY WINDS ASSOCIATED WITH THE MONSOON TROUGH. UPPER LEVEL ANALYSIS
INDICATES THE LLCC IS IN AN ENVIRONMENT OF LOW TO MODERATE VERTICAL
WIND SHEAR WITH INCREASING 850 MB VORTICITY. MAXIMUM SUSTAINED SUR-
FACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRES-
SURE IS ESTIMATED TO BE 1000 MB. DUE TO THE SIGNIFICANT INCREASE IN
DEEP CONVECTION AND IMPROVED OUTFLOW, THE POTENTIAL FOR THE DEVELOP-
MENT 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
061830Z8.//

TROPICAL CYCLONE (TC) 16P (HARVEY), LOCATED APPROXIMATELY 158 NM
NORTH-NORTHEAST OF MORNINGTON ISLAND, HAS TRACKED SOUTHEASTWARD AT 04
KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON
052330Z3 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 25, 30, AND 35
KNOTS. RECENT ANIMATED ENHANCED MULTISPECTRAL AND WATER VAPOR SATELLITE
IMAGERY REVEALS IMPROVED OUTFLOW AND CYCLING DEEP CONVECTION. A
052105Z3 QUIKSCAT PASS DEPICTS A TIGHTLY WRAPPED LOW LEVEL CIRCULATION
CENTER WITH INCREASED WINDS IN THE NORTHWESTERN QUADRANT. DURING THE
NEXT 48 HOURS, TC 16P IS FORECAST TO DRIFT SLOWLY SOUTHWESTWARD AS
IT REMAINS IN A WEAK STEERING ENVIRONMENT. THE INTENSITY SHOULD SLOW-
LY RISE DUE TO DECREASED SURFACE INFLOW AND WEAK UPPER LEVEL OUTFLOW.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 060000Z6 IS 10 FEET. THIS WARNING
