---> Tropical Cyclone KIRRILY Track Map and Data

WTXS21 PGTW 20000126 21:30z
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
160 NM EITHER SIDE OF A LINE FROM 14.6S1 111.0E3 TO 21.1S4 115.0E7
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
261730Z9 INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 15.7S3
111.6E9.  THE SYSTEM IS MOVING SOUTHEASTWARD AT 10 KNOTS.
2. REMARKS: A RECENT SCATTEROMETER IMAGE INDICATED A DEFINED LOW
LEVEL CIRCULATION CENTER (LLCC) ASSOCIATED WITH THE CONVECTION. 200
MB ANALYSIS INDICATES THE CONVECTION IS SLOWLY MOVING UNDER THE AXIS
OF THE UPPER LEVEL RIDGE, WHICH SHOULD PROVIDE IMPROVED OUTFLOW
ALOFT. UW-CIMSS WIND SHEAR CHARTS ALSO INDICATE DECREASING VERTICAL
SHEAR CLOSER TO THE SHORE OF NORTHWESTERN AUSTRALIA AND IN THE PATH
OF THE DISTURBANCE. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED NEAR
1000 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS GOOD.

270530Z7 VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON CURRENT INTENSITY ESTIMATES OF 25 AND 30 KNOTS. ANIMATED MULTI-

SOUTHWESTERN AUSTRALIA IS FORECAST TO BUILD NORTHEASTWARD OVER
KIMBERLEY BY THE 36 HOUR PERIOD. THEREFORE, TC 09S SHOULD TRACK
INITIALLY, SOUTH-SOUTHEASTWARD BEFORE MAKING A TURN TOWARD THE
SOUTHWEST AFTER THE 36 HOUR PERIOD. TC 09S IS FORECAST TO INTENSIFY

TROPICAL CYCLONE (TC) 09S, LOCATED APPROXIMATELY 250 NM NORTH-
NORTHWEST OF LEARMONTH AUSTRALIA, HAS TRACKED SOUTH-SOUTHWESTWARD AT
07 KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
271730Z0 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON CURRENT INTENSITY ESTIMATES OF 30 AND 45 KNOTS. ANIMATED INFRARED

RECENTLY BUILT OVER THE PREVIOUSLY EXPOSED LOW LEVEL CIRCULATION
CENTER (LLCC). THE SYSTEM HAS TRACKED WITHIN THE STEERING FLOW OF
THE SUBTROPICAL RIDGE TO THE SOUTHEAST. TC 09S IS FORECAST TO TRACK
SOUTH-SOUTHWESTWARD, BECOMING MORE SOUTHWESTWARD AS THE SUBTROPICAL
RIDGE OVER NORTHWEST AUSTRALIA BUILDS SLOWLY TOWARDS THE WEST.
ANIMATED WATER VAPOR IMAGERY INDICATES IMPROVING OUTFLOW ALOFT WITH
DECREASING VERTICAL SHEAR ACROSS THE REGION. TC 09S IS FORECAST TO
INTENSIFY AT A NEAR CLIMATOLOGICAL RATE. INCREASING VERTICAL SHEAR
MAY BEGIN TO INHIBIT DEVELOPMENT AFTER THE 36 TO 48 HOUR FORECAST

TROPICAL CYCLONE (TC) 09S (KIRRILY), LOCATED APPROXIMATELY 470 NM
WEST OF LEARMONTH AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT 09 KNOTS
OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 291730Z2
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
CURRENT INTENSITY ESTIMATES OF 77 AND 65 KNOTS. CURRENT ANIMATED
SATELLITE IMAGERY SHOWS WEAKENING OF THE SYSTEM, WITH ELONGATION TO
THE SOUTHEAST. A 291404Z0 SSMI PASS INDICATES A VERY BROAD LOW LEVEL
CIRCULATION CENTER ASSOCIATED WITH THE SYSTEM, HOWEVER THE
CONVECTION IS CONFINED TO THE VERY CENTER. THERE IS NO LONGER ANY
EVIDENCE OF ANY TYPE OF EYE. 200 MB ANALYSIS INDICATES THE UPPER-
LEVEL RIDGE AXIS REMAINS SOUTH OF THE SYSTEM, AND AN UPPER LEVEL JET
IS EVIDENT TO THE SOUTHWEST. TC 09S (KIRRILY) IS FORECAST TO TRACK
WEST-SOUTHWESTWARD UNDER THE STEERING INFLUENCE OF THE MID-LEVEL
SUB-TROPICAL RIDGE TO THE SOUTH. TC 09S (KIRRILY) IS FORECAST TO
WEAKEN THROUGH THE FORECAST PERIOD AS THE SYSTEM MOVES INTO
INCREASING VERTICAL WIND SHEAR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
291800Z0 IS 22 FEET. NEXT WARNINGS AT 300900Z2 (DTG 300755Z0) AND
