REMARKS:
142100Z POSITION NEAR 13.2S 70.4E.
TROPICAL CYCLONE (TC) 01S (ANJA), LOCATED APPROXIMATELY 370 NM SOUTH-
SOUTHWEST OF DIEGO GARCIA, HAS TRACKED SOUTHWESTWARD AT 04 KNOTS
OVER THE PAST SIX HOURS. THE CYCLONE HAS CONTINUED TO INTENSIFY
UNDER LOW VERTICAL WIND SHEAR AND FAVORABLE (WESTWARD AND POLEWARD)
VENTING ALOFT. THE INITIAL FORECAST INTENSITY IS 45 KNOTS AND IS
BASED ON DVORAK ESTIMATES FROM PGTW AND FMEE RANGING FROM 35 TO 45
KNOTS. A WELL-DEFINED MICROWAVE EYE, EVIDENT IN NUMEROUS IMAGES OVER
THE PAST 12 HOURS, SUGGESTS AN INTENSITY OF AT LEAST 45 KNOTS
DESPITE A SOMEWHAT WEAK CONVECTIVE SIGNATURE IN ENHANCED WATER VAPOR
IMAGERY. ANJA IS FORECAST TO TRACK GENERALLY SOUTHWESTWARD OVER THE
NEXT 3 DAYS UNDER THE STEERING INFLUENCE OF A BUILDING RIDGE CENTER
TO THE EAST. THE RIDGING WILL SLOWLY ERODE AS A LONGWAVE TROUGH
PASSES TO THE SOUTH NEAR DAY 4 AND WILL INITIATE RECURVATURE INTO
THE MID-LATITUDE FLOW. THE SYSTEM WILL LIKELY INTENSIFY TO A PEAK
INTENSITY OF 70 KNOTS JUST PRIOR TO RECURVATURE DUE TO ENHANCED
POLEWARD OUTFLOW AHEAD OF THE AFOREMENTIONED TROUGH. OCEAN HEAT
CONTENT WILL DROP DRAMATICALLY THEREAFTER AND VERTICAL WIND SHEAR
WILL INCREASE AS WELL. THESE FACTORS WILL CONTRIBUTE TO GRADUAL
WEAKENING AS ANJA BEGINS TO ACCELERATE POLEWARD. THIS FORECAST TRACK
REFLECTS THE MODEL CONSENSUS AND HAS BEEN SHIFTED WEST OF THE
PREVIOUS FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 141800Z IS 14
FEET. NEXT WARNINGS AT 150900Z AND 152100Z.//

TROPICAL CYCLONE (TC) 01S (ANJA), LOCATED APPROXIMATELY 360 NM SOUTH-

PAST 06 HOURS. THERE HAVE BEEN SIGNIFICANT CHANGES SINCE THE
PREVIOUS WARNING. THE SYSTEM WAS LIKELY MUCH STRONGER THAN 45 KNOTS
AT 141800Z BASED ON A SLEW OF MICROWAVE IMAGERY THAT INDICATED
INTENSE CONVECTION SURROUNDING AN EYE. DVORAK ESTIMATES HAVE BEEN
MISREPRESENTATIVE OF THE ACTUAL INTENSITY BASED ON THE SMALL SIZE OF
THE SYSTEM. SINCE DEVELOPING A 16 NM EYE AT AROUND 142230Z THE
DVORAK ESTIMATES FROM PGTW HAVE BECOME MORE REPRESENTATIVE OF WHAT
THE MICROWAVE IMAGERY INDICATES. ACCORDINGLY THE INITIAL INTENSITY
OF THIS FORECAST HAS BEEN INCREASED TO 90 KNOTS BASED ON A 5.0
DVORAK CURRENT INTENSITY FROM PGTW. IN ADDITION TO THE PREVIOUS
INTENSITY UNDERESTIMATE, THE SYSTEM HAS UNDERGONE RAPID
INTENSIFICATION. AN UPPER LEVEL LONGWAVE TROUGH PROPAGATING TOWARDS
THE WESTERN COAST OF AUSTRALIA HAS ENHANCED POLEWARD OUTFLOW
IMMENSELY, WHICH HAS ALLOWED CONVECTION TO DEEPEN NEAR THE CENTER.
AND LASTLY, THE SYSTEM HAS BECOME QUASISTATIONARY. THE MOST CURRENT
MODEL FIELDS SUGGEST THAT THIS STALL IS A RESULT OF A NARROW
EXTENSION OF DEEP-LAYER RIDGING THAT HAS BUILT INTO THE SOUTH OF THE
SYSTEM FROM THE EAST, IN ADDITION TO THE COMPETING ASPECTS OF THE
DEEP-LAYER NEAR EQUATORIAL RIDGE TO THE NORTH. THE SYSTEM IS
EXPECTED TO GRADUALLY PICK UP SPEED OVER THE NEXT FEW DAYS AS IT
TRACKS GENERALLY WESTWARD ALONG THE RIDGE TO THE SOUTH. NEAR TAU 72
A LONGWAVE TROUGH WILL ERODE THIS RIDGE, AND WILL PROMOTE A MORE
POLEWARD TRACK. THE SYSTEM WILL THEN BEGIN TO WEAKEN DUE TO
INCREASED VERTICAL WIND SHEAR ASSOCIATED WITH THE AFOREMENTIONED
TROUGH AND DUE TO SIGNIFICANTLY LOWER OCEANIC HEAT CONTENT. A PEAK
INTENSITY OF 110 KNOTS IS CONSISTENT WITH THE INITIAL INTENSITY OF
90 KNOTS AND A MORE CLIMATOLOGICAL RATE OF INTENSIFICATION.
ENVIRONMENTAL CONDITIONS ARE EXPECTED TO REMAIN FAVORABLE FOR
CONTINUED INTENSIFICATION UNTIL ABOUT TAU 72. THE FORECAST TRACK
CLOSELY FOLLOWS THE MODEL CONSENSUS, THOUGH IT IS MUCH SLOWER IN THE
EARLIER TAUS TO ACCOUNT FOR THE RECENT SLOW DOWN. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 150000Z IS 18 FEET. NEXT WARNINGS AT
151500Z AND 160300Z.//
