CATEGORY 2 US
MAKING LANDFALL
REMARKS:
190300Z POSITION NEAR 13.0S 143.8E.
TROPICAL CYCLONE (TC) 20P (TREVOR), LOCATED APPROXIMATELY 773 NM EAST
OF DARWIN, AUSTRALIA, HAS TRACKED WESTWARD AT 05 KNOTS OVER THE
PAST SIX HOURS. TC 20P UNDERWENT EXTREME RAPID INTENSIFICATION (RI)
WITH A PEAK OF ABOUT 100 KNOTS AT 18/2100Z. AS INDICATED IN ANIMATED
ENHANCED INFRARED SATELLITE IMAGERY AND WEIPA RADAR IMAGERY, THE
SYSTEM HAS BEGUN TO WEAKEN SLIGHTLY SINCE 18/2100Z AS IT BEGINS TO
MAKE LANDFALL; HOWEVER, 20P HAS MAINTAINED AN OBLONG EYE. THEREFORE,
THE CURRENT INTENSITY IS ASSESSED AT 95 KNOTS BASED ON DVORAK
CURRENT INTENSITY ESTIMATES RANGING FROM 5.0 TO 5.5 (90 TO 102
KNOTS). UPPER-LEVEL ANALYSIS INDICATES RADIAL OUTFLOW, ENHANCED BY
THE WESTERLIES TO THE SOUTH, AND LOW VERTICAL WIND SHEAR. TC 20P IS
FORECAST TO TRACK WESTWARD THROUGH TAU 48 UNDER THE STEERING
INFLUENCE OF THE SUBTROPICAL RIDGE (STR) TO THE SOUTHWEST AND SOUTH.
AFTER TAU 48, THE SYSTEM WILL TURN WEST-SOUTHWESTWARD THEN
SOUTHWESTWARD AS THE STR SHIFTS EAST AND SOUTHEAST OF THE SYSTEM AND
REORIENTS AS A DEEP MIDLATITUDE SHORTWAVE TROUGH DEEPENS OVER
CENTRAL AUSTRALIA. NUMERICAL MODEL GUIDANCE IS IN FAIR AGREEMENT
WITH A LARGE SPREAD IN SOLUTIONS AND HIGH UNCERTAINTY PRIMARILY DUE
TO DIFFERENCES IN THE TIMING OF THE TURN WEST-SOUTHWESTWARD AND
MAJOR DIFFERENCES IN TRACK SPEEDS. THE JTWC FORECAST TRACK FAVORS
THE ECMWF DETERMINISTIC SOLUTION AND THE ECMWF ENSEMBLE SOLUTION BUT
IS POSITIONED SLIGHTLY FASTER THAN THE MULTI-MODEL CONSENSUS. TC 20P
IS FORECAST TO WEAKEN RAPIDLY AS IT CROSSES THE CAPE YORK PENINSULA
BUT IS EXPECTED TO RE-INTENSIFY OVER THE GULF OF CARPENTARIA AFTER
TAU 36. THE SYSTEM IS FORECAST TO UNDERGO RI AFTER TAU 48 DUE TO
VERY WARM SST (30-32C), HIGH OCEAN HEAT CONTENT VALUES, FAVORABLE
OUTFLOW AND LOW VERTICAL WIND SHEAR. NEAR TAU 96, TC 20P WILL MAKE
LANDFALL, TRACK INLAND AND STEADILY WEAKEN. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 190000Z IS 21 FEET. NEXT WARNINGS AT 190900Z, 191500Z,
192100Z AND 200300Z.//
