REMARKS:
010300Z4 POSITION NEAR 15.8S4 152.7E5. THE SUSPECT AREA WHICH
WAS UNDER A TROPICAL CYCLONE FORMATION ALERT (WTPS21 PGTW
311500), EAST OF THE CAPE YORK PENINSULA, HAS DEVELOPED INTO
TROPICAL CYCLONE 22P (TESSI). TROPICAL CYCLONE 22P (TESSI),
SITUATED ABOUT 450 NM EAST OF THE CAPE YORK PENINSULA, HAS
TRACKED WEST-SOUTHWESTWARD AT 07 KNOTS DURING THE PAST 6 HOURS. THE
WARNING POSITION IS BASED ON 312330Z2 VISIBLE SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY
ESTIMATES OF 35 KNOTS. ANIMATED VISIBLE IMAGERY DEPICTS A CONVECTIVE
BAND DEVELOPING OVER THE NORTHEAST QUADRANT. A 312251Z4 SPECIAL
SENSOR MICROWAVE IMAGER (SSM/I) PASS SHOWED THE CONVECTION WRAPPING
IN TOWARD THE LOW-LEVEL CIRCULATION CENTER FROM THE SOUTHWEST.
LOW/MID-LEVEL HIGH SITUATED SOUTHEAST OF NEW CALEDONIA IS EXPECTED
TO BUILD OVER THE EAST CENTRAL COAST OF AUSTRALIA THROUGH THE
PERIOD. TC 22P SHOULD TRACK WEST-SOUTHWESTWARD THROUGH THE PERIOD.
THE SYSTEM IS FORECAST TO INTENSIFY AT A CLIMATOLOGICAL RATE BEFORE
MOVING ONSHORE AT THE END OF THE FORECAST PERIOD. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 010000Z1 IS 12 FEET. THIS WARNING

011500Z7 POSITION NEAR 16.3S0 151.8E5.
TROPICAL CYCLONE (TC) 22P (TESSI), LOCATED APPROXIMATELY 360 NM EAST
OF CAIRNS, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT 06 KNOTS
DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 011130Z6
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 45 KNOTS AND SYNOPTIC DATA.
ANIMATED INFRARED IMAGERY DEPICTS A WELL-ORGANIZED SYSTEM WITH
IMPROVING CONVECTION AROUND THE SYSTEM CENTER. A 011126Z1 SPECIAL
SENSOR MICROWAVE IMAGER PASS SHOWS DEEP CONVECTION BEGINNING TO
CONSOLIDATE AND WRAP INTO THE CENTER. TC 22P (TESSI) IS EXPECTED TO
TRACK UNDER THE STEERING INFLUENCE OF THE LOW TO MID-LEVEL
SUBTROPICAL RIDGE, WHICH EXTENDS FROM SOUTH OF NEW CALEDONIA INTO
SOUTHEASTERN AUSTRALIA. THE SYSTEM IS FORECAST TO INTENSIFY AT A
NEAR CLIMATOLOGICAL RATE AS IT TRACKS UNDER INCREASING VERTICAL WIND
SHEAR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 011200Z4 IS 12 FEET.

TROPICAL CYCLONE (TC) 22P (TESSI) MOVED ONSHORE ABOUT 20 NM SOUTH OF
LUCINDA, AUSTRALIA AT 022030Z7. CITIES WITHIN THE AREA REPORTED
SUSTAINED WINDS OF GALE FORCE (34 TO 47 KNOTS). TROPICAL CYCLONE
(TC) 22P (TESSI) HAS TRACKED WESTWARD AT 08 KNOTS DURING THE PAST 6
HOURS. THE WARNING POSITION IS BASED ON 022330Z0 VISIBLE AND
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 30 KNOTS, AND SYNOPTIC
DATA. MICROWAVE IMAGERY AND THE TOWNSVILLE RADAR LOOP INDICATED THAT
THE MAJORITY OF THE CONVECTION AND ASSOCIATED HEAVY PRECIPITATION IS
PRIMARILY CONFINED TO THE SOUTHERN HALF OF THE SYSTEM. TC 22P
(TESSI) IS EXPECTED TO TRACK WESTWARD AND DISSIPATE. THIS IS THE
FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER
(NAVPACMETOCCEN). THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF
REGENERATION. REFER TO TROPICAL CYCLONE  21S (HUDAH) WARNINGS
(WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES. REFER TO TROPICAL CYCLONE
