MSGID/GENADMIN/NAVPACMETOCCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
180 NM EITHER SIDE OF A LINE FROM 15.0S 126.2E TO 16.1S 119.4E
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 IM-
AGERY AT 291830Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 15.0S 125.9E. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 06
KNOTS.
2. REMARKS:
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 15.1S 128.5E, IS
NOW LOCATED NEAR 15.0S 125.9E, APPROXIMATELY 330 NM WEST-SOUTHWEST
OF DARWIN, AUSTRALIA. LOCAL AREA RADAR AND SURFACE WIND OBSERVAT-
IONS CONTINUE TO PROVIDE EVIDENCE FOR A DEVELOPING LOW-LEVEL CIRC-
ULATION CENTER (LLCC) OVER LAND. THE DISTURBANCE IS CURRENTLY IN A
REGION OF MODERATE VERTICAL WIND SHEAR WITH THE MAJORITY OF CONVE-
CTION SHEARED TO THE WEST OF THE LLCC. THE SYSTEM IS SHOWING SIGNS
OF RADIAL OUTFLOW FORMING TO THE NORTH AND SOUTH OF THE LLCC. THE
SYSTEM IS FORECAST TO MOVE OVER WATER WITHIN THE NEXT 12 HOURS, AND
COULD RAPIDLY DEVELOP INTO A TROPICAL CYCLONE UPON ENCOUNTERING THE
MORE FAVORABLE OVER-WATER CONDITIONS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED TO BE NEAR 1000 MB. DUE TO ITS PROXIMITY TO WATER AND
AN IMPROVING UPPER LEVEL ENVIRONMENT, THE POTENTIAL FOR THE DEVELO-
PMENT 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
011930Z.

REMARKS:
010900Z POSITION NEAR 15.4S 122.9E.
TROPICAL CYCLONE (TC) 21S (NONAME) LOCATED APPROXIMATELY
400 NM NORTHEAST OF PORT HEDLAND, AUSTRALIA, HAS TRACKED
WESTWARD AT 10 KNOTS OVER THE PAST 06 HOURS. SATELLITE
INTENSITY ESTIMATES OF 35 KNOTS FROM ALL AVAILABLE AGENCIES
SUPPORT THE INITIAL INTENSITY. RECENT ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS DEEP CONVECTION NEAR THE CENTER OF
AN ORGANIZED LOW-LEVEL CIRCULATION CENTER (LLCC). TC 21S
WILL CONTINUE TO TRACK GENERALLY WEST TO WEST-SOUTHWESTWARD
THROUGHOUT THE FORECAST PERIOD DUE TO A DEVELOPING LOW TO
MID-LEVEL STEERING RIDGE TO THE SOUTH OF THE SYSTEM. TC 21S
IS FORECAST TO STEADILY INTENSIFY DUE TO FAVORABLE UPPER LEVEL
OUTFLOW AND LIGHT TO MODERATE VERTICAL WIND SHEAR. OCEAN HEAT
CONTENT WILL BE MARGINAL THROUGH TAU 12, BUT THE OCEAN HEAT
CONTENT IS EXPECTED TO INCREASE AS THE STORM TRACKS WESTWARD.
THIS WILL ALSO CONTRIBUTE TO THE GRADUAL INTENSIFICATION OF
THE STORM. THE TRACK FORECAST IS CLOSE TO THE CONSENSUS OF
THE NUMERICAL AIDS, WHICH ARE IN GOOD AGREEMENT. THE INTENSITY
FORECAST IS SLIGHTLY HIGHER THAN THE NUMERICAL GUIDANCE DUE
TO THE AFOREMENTIONED FAVORABLE INFLUENCES. THIS WARNING

REMARKS:
020900Z POSITION NEAR 16.6S 120.3E.
TROPICAL CYCLONE (TC) 21S (OPHELIA) LOCATED APPROXIMATELY
515 NM NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED WEST-
SOUTHWESTWARD AT 08 KNOTS OVER THE PAST 06 HOURS. THE FORE-
CAST REASONING FOR TC 21S REMAINS THE SAME AS THE PREVIOUS
FORECAST. TC 21S CONTINUES TO TRACK IN A WEST-SOUTHWESTERLY
DIRECTION ALONG THE NORTHERN PERIPHERY OF THE MID-LEVEL RIDGE
TO THE SOUTH OF THE STORM. THIS TRACK IS EXPECTED TO CONTINUE
THROUGH THE FORECAST PERIOD. TC 21S CONTINUES TO STEADILY
INTENSIFY UNDER FAVORABLE ENVIRONMENTAL CONDITIONS OF LOW
VERTICAL WIND SHEAR AND GOOD EQUATORWARD OUTFLOW. A WEAKER
EASTERLY OUTFLOW CHANNEL HAS DEVELOPED AND IS CONTRIBUTING
TO THE INTENSIFICATION OF THE SYSTEM. TC 21S WILL CONTINUE
TO INTENSIFY THROUGH TAU 48 DUE TO THE AFOREMENTIONED FAVORABLE
CONDITIONS. AFTER THIS TIME THE STORM WILL MAINTAIN INTENSITY
DUE TO THE OFFSETTING FACTORS OF DECREASING OCEAN HEAT CONTENT,
BUT CONTINUED FAVORABLE UPPER LEVEL CONDITIONS. THE TRACK
FORECAST REMAINS CLOSE TO THE CONSENSUS OF THE NUMERICAL AIDS
THAT ARE IN GOOD AGREEMENT. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 020600Z IS 17 FEET. NEXT WARNINGS AT 021500Z, 022100Z,

TROPICAL CYCLONE (TC) 21S (OPHELIA) LOCATED APPROXIMATELY 470 NM
NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED WESTWARD AT 08
KNOTS OVER THE PAST 06 HOURS. THE INTENSITY FORECAST REASONING FOR
TC 21S HAS CHANGED SINCE THE PREVIOUS FORECAST AND LOWER INTENSITIES
ARE NOW FORECAST FOR THE LATER TAUS. TC 21S CONTINUES TO TRACK IN A
WEST TO WEST-SOUTHWESTERLY DIRECTION ALONG THE NORTHERN PERIPHERY OF
THE MID-LEVEL RIDGE TO THE SOUTH OF THE STORM. THIS TRACK IS EXPECTED
TO CONTINUE THROUGH TAU 48. THE STORM WILL THEN BEGIN TO TRACK MORE
SOUTHWESTWARD ALONG THE NORTHWESTERN PERIPHERY OF THE STEERING RIDGE
THROUGH THE REMAINDER OF THE FORECAST PERIOD. TC 21S HAS MAINTAINED
INTENSITY OVER THE PAST 06 HOURS. FAVORABLE ENVIRONMENTAL CONDITIONS
OF LOW VERTICAL WIND SHEAR AND GOOD EQUATORWARD OUTFLOW REMAIN, BUT
DRIER AIR AHEAD OF THE STORM WILL KEEP INTENSIFICATION SLOW THROUGH
TAU 48. AFTER THIS TIME, THE STORM WILL BEGIN TO WEAKEN DUE TO A
DECREASE IN OCEAN HEAT CONTENT AND INCREASE VERTICAL WIND SHEAR. THE

REMARKS:
031500Z POSITION NEAR 16.8S 116.1E.
TROPICAL CYCLONE (TC) 21S (OPHELIA) LOCATED APPROXIMATELY
355 NM NORTH-NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED
WESTWARD AT 08 KNOTS OVER THE PAST 06 HOURS. THE FORECAST
REASONING HAS NOT CHANGED SINCE THE PREVIOUS FORECAST. TC 21S
CONTINUES TO TRACK WEST TO WEST-SOUTHWESTWARD ALONG THE NORTHERN
PERIPHERY OF THE MID-LEVEL RIDGE TO THE SOUTH OF THE STORM.
THIS TRACK IS EXPECTED TO CONTINUE THROUGH TAU 36. THE STORM
WILL THEN BEGIN TO TRACK MORE SOUTHWESTWARD ALONG THE NORTH-
WESTERN PERIPHERY OF THE STEERING RIDGE THROUGH THE REMAINDER
OF THE FORECAST PERIOD. DEEP CONVECTION HAS RE-DEVELOPED OVER
THE CENTER OF THE STORM AND SLIGHT INTENSIFICATION HAS OCCURRED
OVER THE PAST 06 HOURS, WHICH FOLLOWS THE WEAKENING THAT TOOK
PLACE OVER THE PREVIOUS 06 HOURS. MINIMAL INTENSIFICATION IS
EXPECTED OVER THE FIRST 24 TO 36 HOURS DUE FAVORABLE OCEAN HEAT
CONTENT AND LOW TO MODERATE VERTICAL WIND SHEAR. AFTER THIS
TIME, THE STORM WILL BEGIN TO WEAKEN DUE TO A DECREASE IN OCEAN
HEAT CONTENT AND AN INCREASE IN VERTICAL WIND SHEAR. THE FORECAST
REMAINS CLOSE TO THE CONSENSUS OF THE NUMERICAL AIDS, WHICH ARE
IN GOOD AGREEMENT THROUGHOUT THE FORECAST PERIOD. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 031200Z IS 18 FEET. NEXT WARNINGS
AT 032100Z, 040300Z, 040900Z AND 041500Z.//

REMARKS:
040900Z POSITION NEAR 17.9S 113.0E.
TROPICAL CYCLONE (TC) 21S (OPHELIA) LOCATED APPROXIMATELY 280 NM
NORTH OF LEARMONTH, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT
11 KNOTS OVER THE PAST 06 HOURS. THE FORECAST REASONING REMAINS
UNCHANGED FROM THE PREVIOUS FORECAST. TC 21S WILL CONTINUE TO
TRACK GENERALLY SOUTHWESTWARD ALONG THE PERIPHERY OF A MID-LEVEL
RIDGE TO THE SOUTHEAST OF THE STORM THROUGH TAU 36. THEREAFTER,
THE POLEWARD COMPONENT OF STORM MOTION WILL INCREASE AS THE STORM
CONTINUES TRACKING AROUND THE STEERING RIDGE PERIPHERY TOWARD THE
BASE OF AN APPROACHING TROUGH SOUTHWEST OF AUSTRALIA. THE STORM
HAS MAINTAINED INTENSITY OVER THE PAST 06 HOURS IN RESPONSE TO
THE COMPETING INFLUENCES OF FAVORABLE OCEAN HEAT CONTENT AND LESS-
THAN-OPTIMAL UPPER LEVEL OUTFLOW. HOWEVER, RECENT ANIMATED WATER
VAPOR IMAGERY SHOWS IMPROVING MULTI-DIRECTIONAL OUTFLOW ALOFT,
WHICH SHOULD SUPPORT SOME INTENSIFICATION OVER THE NEXT 12 HOURS.
THEREAFTER, DECREASING OCEAN HEAT CONTENT AND INCREASING VERTICAL
WIND SHEAR WILL LIMIT FURTHER INTENSIFICATION AND EVENTUALLY PRO-
DUCE A WEAKENING TREND. BY TAU 72, THESE NEGATIVE EFFECTS SHOULD
REDUCE STORM INTENSITY TO THE WARNING THRESHOLD OF 35 KNOTS. THE
FORECAST TRACK AND INTENSITY REMAIN CLOSE TO THE CONSENSUS OF THE
NUMERICAL AND STATISTICAL MODELS, WHICH ARE IN CLOSE AGREEMENT.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 040600Z IS 23 FEET. NEXT

042100Z POSITION NEAR 18.7S 111.4E.
TROPICAL CYCLONE (TC) 21S (OPHELIA) LOCATED APPROXIMATELY 260 NM
NORTH-NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED WEST-SOUTH-
WESTWARD AT 09 KNOTS OVER THE PAST 06 HOURS. THE FORECAST REASON-
ING REMAINS UNCHANGED FROM THE PREVIOUS FORECAST. TC 21S WILL
CONTINUE TO TRACK GENERALLY SOUTHWESTWARD ALONG THE PERIPHERY OF
A MID-LEVEL RIDGE TO THE SOUTHEAST OF THE STORM THROUGH FORECAST
PERIOD. THE STORM HAS DECREASED INTENSITY OVER THE PAST 06 HOURS
IN RESPONSE TO INCREASED VERTICAL WIND SHEAR AND DRY AIR INTRUSION.
DECREASING OCEAN HEAT CONTENT AND INCREASING VERTICAL WIND SHEAR
ARE EXPECTED TO WEAKEN THE STORM FURTHER, RESULTING IN FULL DIS-
SIPATION BELOW THE 35 KNOT WARNING THRESHOLD PRIOR TO TAU 48. THE
FORECAST TRACK AND INTENSITY REMAIN CLOSE TO THE CONSENSUS OF THE
NUMERICAL AND STATISTICAL MODELS, WHICH ARE IN CLOSE AGREEMENT.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 041800Z IS 20 FEET. NEXT
