TROPICAL CYCLONE 16P (SIXTEEN), LOCATED APPROXIMATELY 349 NM EAST-NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED EASTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A CONSOLIDATING SYSTEM WITH A DEVELOPING CONVECTIVE BAND WRAPPING IN FROM THE WEST. THE INITIAL INTENSITY ASSESSMENT OF 35 KNOTS IS BASED ON A DVORAK ESTIMATE OF T2.5 (35 KNOTS) FROM ADRM, COUPLED WITH A 220054Z ASCAT IMAGE SHOWING A LARGE AREA OF 30-35 KNOT WINDS IN THE WESTERN SEMICIRCLE. ENVIRONMENTAL ANALYSIS SHOWS MODERATE (10-20 KNOT) VERTICAL WIND SHEAR (VWS), EXCELLENT EQUATORWARD AND POLEWARD OUTFLOW, AND WARM SSTS (29-30C). TC 16P IS BEING STEERED BY A NORTH-SOUTH ORIENTED RIDGE TO ITS EAST. THE STORM IS FORECAST TO TRACK SOUTHEASTWARD THROUGH TAU 36 BEFORE TURNING TO THE SOUTH AND EVENTUALLY TO THE WEST AS A RIDGE BUILDS IN OVER CENTRAL AUSTRALIA. THE STORM WILL INTENSIFY, SLOWLY AT FIRST, THEN MORE RAPIDLY AS VWS DECREASES. THE PEAK INTENSITY IS ESTIMATED AT 85 KNOTS BY TAU 48. DYNAMIC MODEL GUIDANCE HAS A LARGE SPREAD, WITH SEVERAL MODELS BRINGING IT SOUTHEAST INTO THE CAPE OF YORK AND OTHER MODELS TURNING IT BACK TO THE WEST AFTER COMING ASHORE IN THE SOUTHERN GULF OF CARPENTARIA. THIS SPREAD IS LEADING TO LOW CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 221200Z IS 10 FEET. NEXT WARNINGS AT 222100Z, 230300Z, 230900Z AND 231500Z. https://icons.wunderground.com/data/...01816_5day.gif

TROPICAL CYCLONE 16P (NORA), LOCATED APPROXIMATELY 386 NM EAST- NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED EASTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS DEEP BANDING CONVECTION RAPIDLY CONSOLIDATING AROUND THE LOW LEVEL CIRCULATION CENTER STRUGGLING TO FORM AN EYE. A 222116Z 37 GHZ SSMIS IMAGE SHOWS A WEAK LOW LEVEL MICROWAVE EYE FEATURE. THE INITIAL INTENSITY IS ASSESSED AT 55 KNOTS WHICH IS BASED ON RECENT DVORAK ESTIMATES OF T3.5 (55 KNOTS) FROM PGTW AND ADRM. NEARBY SHIP AND SURFACE OBSERVATIONS FROM CAPE WESSEL INDICATE A SHARP INCREASE IN SUSTAINED WINDS AROUND 35 KNOTS WITH A CORRESPONDING DECREASE IN MSLP TO 997 MB. UPPER-LEVEL ANALYSIS SHOWS A VERY FAVORABLE WIND SHEAR ENVIRONMENT WITH EXCELLENT DIFFLUENCE DUE TO A POINT SOURCE ANALYZED JUST ABOVE THE SYSTEM. SSTS IN THE REGION ARE ALSO EXTREMELY WARM NEAR 30 CELSIUS WITH NOTABLE OCEANIC HEAT CONTENT IN THE ARAFURA SEA EXTENDING INTO THE GULF OF CARPENTARIA. TC 16P IS CURRENTLY TRACKING SLOWLY EASTWARD IN A WEAK STEERING ENVIRONMENT. A WEAK RIDGE IS BUILDING JUST EAST OF TC 16S WILL SHIFT THE TRACK INCREASINGLY MORE SOUTHWARD OVER THE NEXT 48 HOURS. VERY FAVORABLE UPPER-LEVEL CONDITIONS WORKING IN CONCERT WITH THE WARM WATERS WILL FAVOR THE RAPID DEVELOPMENT OF TC 16P IN THE NEAR TERM, REACHING A PEAK INTENSITY OF 120 KNOTS BY TAU 36. THEREAFTER, TC 16P WILL BEGIN WEAKENING AS IT NEARS LAND AND SLOWS DOWN AS A SUBTROPICAL RIDGE CURRENTLY TO THE SOUTHWEST WILL BUILD IN SOUTH OF TC 16P AND SHIFT THE TRACK WEST-SOUTHWESTWARD IN THE EXTENDED PERIOD. TC 16S WILL MAKE LANDFALL JUST BEFORE TAU 96 AND WILL WEAKEN SIGNIFICANTLY AS IT TRACKS OVER THE CONTINENT. DYNAMIC MODEL GUIDANCE IS SHOWING SOME IMPROVEMENT, BUT A LARGE DEGREE OF UNCERTAINTY REMAINS AS THE LEVEL OF INFLUENCE THE EASTWARD RIDGE WILL HAVE IN THE SHORT TERM IS UNKNOWN. THE MESOSCALE MODELS FAVOR A TRACK MORE EASTWARD WHILE THE GLOBAL MODELS FAVOR A WESTWARD TRACK KEEPING THE SYSTEM OVER OPEN WATER AND UNHINDERED BY LAND A BIT LONGER. THE JTWC FORECAST TRACK IS HEDGED TOWARD THE GLOBAL SOLUTIONS TAKING INTO ACCOUNT A MORE PRONOUNCED EASTERN RIDGE, HOWEVER, DUE TO THESE UNCERTAINTIES THERE IS OVERALL LOW CONFIDENCE IN THE FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 230000Z IS 18 FEET. NEXT WARNINGS AT 230900Z, 231500Z, 232100Z AND 240300Z. https://icons.wunderground.com/data/...01816_5day.gif

TROPICAL CYCLONE 16P (NORA), LOCATED APPROXIMATELY 438 NM EAST- NORTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. THE CURRENT POSITION IS BASED ON RADAR IMAGERY FROM GOVE, AUSTRALIA, RECENT SATELLITE FIXES FROM MULTIPLE REPORTING AGENCIES AND A PARTIAL 230607Z SSMI 37 GHZ MICROWAVE IMAGE SHOWING A CLEAR CENTER FEATURE. THE CURRENT INTENSITY IS CONSISTENT WITH A CONSENSUS OF SUBJECTIVE DVORAK CURRENT INTENSITY ESTIMATES AND AUTOMATED INTENSITY FIX DATA FROM CIMSS AND CIRA. TC 16S HAS TURNED TOWARD THE SOUTHEAST AND ACCELERATED OVER THE PAST SIX HOURS UNDER THE STEERING INFLUENCE OF AN EXTENSION OF A NEAR-EQUATORIAL RIDGE TO THE NORTHEAST. STORM STRUCTURE CONTINUES TO IMPROVE AS THE SYSTEM INTENSIFIES, WITH DEEP CONVECTION FLARING AROUND A DEVELOPING EYEWALL EVIDENT IN MICROWAVE SATELLITE IMAGERY AND RADAR DATA. TC 16S IS EXPECTED TO TRACK POLEWARD UNDER THE CONTINUED INFLUENCE OF THE CURRENT STEERING RIDGE OVER THE NEXT 72 HOURS. AROUND TAU 72, THE SYSTEM WILL ENTER A COMPETING STEERING ENVIRONMENT AS A SUBTROPICAL RIDGE BUILDING TO THE SOUTH EXERTS AN INCREASING INFLUENCE ON STORM MOTION. SLOW FORWARD MOTION IS EXPECTED IN THE 72 TO 96 HOUR TIME FRAME AS THE PRIMARY STEERING MECHANISM TRANSITIONS TO THE SUBTROPICAL RIDGE, WITH ACCELERATION WESTWARD LIKELY THEREAFTER. RAPID INTENSIFICATION IS ANTICIPATED OVER THE NEXT 24 TO 36 HOURS AS TC 16S PASSES OVER VERY WARM WATER IN THE GULF OF CARPENTARIA AND UPPER-LEVEL FLOW SUPPORTS. WEAKENING IS EXPECTED AFTER TAU 36 AS THE UPPER-LEVEL FLOW PATTERN BECOMES LESS FAVORABLE. TC 16S WILL DISSIPATE BY TAU 120 AS IT MOVES INLAND. NUMERICAL MODELS ARE IN GOOD GENERAL AGREEMENT WITH THE POLEWARD TRACK SCENARIO THROUGH TAU 72, BUT DIVERGE IN THE EXTENDED PERIOD DUE TO DIFFERING DEPICTIONS OF THE EVOLUTION OF THE CURRENT AND ANTICIPATED STEERING RIDGE. THE CURRENT FORECAST LIES CLOSE TO THE MAJORITY SOLUTION AND THE MULTI-MODEL CONSENSUS WITH HIGH CONFIDENCE THROUGH LANDFALL AND LOW CONFIDENCE IN THE EXTENDED PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 230600Z IS 20 FEET. NEXT WARNINGS AT 231500Z, 232100Z, 240300Z AND 240900Z. https://icons.wunderground.com/data/...01816_5day.gif

TROPICAL CYCLONE (TC) 16P (NORA), LOCATED APPROXIMATELY 478 NM NORTHWEST OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT 8 KNOTS OVER THE PAST SIX HOURS. ENHANCED INFRARED IMAGERY SHOWS THAT TC NORA HAS CEASED ITS RAPID INTENSIFICATION PHASE, AT LEAST TEMPORARILY, WITH THE SYSTEM STRUGGLING TO MAINTAIN AN EYE. THE INITIAL POSITION IS BASED ON ANALYSIS OF THE INFRARED IMAGERY, AS WELL AS A 231715 SSMI 37 GHZ MICROWAVE IMAGE, DEPICTING A WEAK MICROWAVE EYE FEATURE DISPLACED SOMEWHAT TO THE NORTHEAST FROM WHERE THE IR WOULD SUGGEST THE LLCC WOULD BE. THIS ASSESSMENT IS SUPPORTED BY ANALYSIS OF RADAR IMAGERY FROM THE GOVE, AUSTRALIA RADAR SITE. THE INITIAL INTENSITY REMAINS AT 95 KNOTS, CONSISTENT WITH SUBJECTIVE DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM T5.5 (102 KNOTS) TO T5.0 (90 KNOTS) AND AUTOMATED INTENSITY GUIDANCE FROM CIMSS OF T5.0. TC 16P HAS TRACKED SOUTHEASTWARD OVER THE PAST SIX HOURS ALONG THE WESTERN PERIPHERY OF A NEAR EQUATORIAL RIDGE (NER) CENTERED OVER EASTERN NEW GUINEA. AS PREVIOUSLY MENTIONED, INTENSITY HAS PLATEAUED OVER THE PAST 12 HOURS, LIKELY DUE TO AN EYEWALL REPLACEMENT CYCLE AS WELL AS RELATIVELY WEAK UPPER-LEVEL OUTFLOW. TC 16P IS FORECAST TO CONTINUE TRACKING SOUTH-SOUTHEASTWARD UNDER THE STEERING INFLUENCE OF THE NER OVER THE NEXT 36 HOURS. AROUND TAU 48, THE SYSTEM WILL SLOW DOWN AND BECOME NEARLY QUASI-STATIONARY AS IT ENTERS A WEAK STEERING ENVIRONMENT BETWEEN THE NER AND A BUILDING SUBTROPICAL RIDGE (STR) TO THE SOUTH. BEYOND TAU 72, TC 16P WILL ACCELERATE WESTWARD AS THE STR BECOMES THE PRIMARY STEERING MECHANISM THROUGH THE REMAINDER OF THE FORECAST. A SHORT PERIOD OF ADDITIONAL INTENSIFICATION IS FORECAST THROUGH 24, PEAKING AT 105 KNOTS, AS THE SYSTEM PASSES OVER VERY WARM WATER IN THE GULF OF CARPENTARIA WITH LOW TO MODERATE VWS AND MODERATE SUPPORTING UPPER- LEVEL OUTFLOW. AFTER TAU 36, WEAKENING IS EXPECTED AS THE UPPER- LEVEL FLOW PATTERN BECOMES LESS FAVORABLE. THE WEAKENING TREND WILL ACCELERATE THROUGH TAU 72, AS THE SYSTEM BECOMES QUASI-STATIONARY IN THE SOUTHEASTERN GULF OF CARPENTARIA AS DRY AIR ENTRAINMENT, LAND INTERACTION AND INCREASING CONVERGENCE ALOFT WILL COMBINE TO RAPIDLY WEAKEN THE SYSTEM. TC 16P WILL DISSIPATE OVER LAND BY TAU 120. AVAILABLE MODEL GUIDANCE IS IN GOOD AGREEMENT THOUGH TAU 24, BUT SHOWS SIGNIFICANT UNCERTAINTY THEREAFTER. NEARLY ALL MODELS INDICATE A PERIOD OF SLOW MOVEMENT AROUND TAU 72 FOLLOWED BY ACCELERATION TOWARDS THE WEST, THE UNCERTAINTY BEING IN THE TIMING AND SPEED OF MOTION. HOWEVER, THE AFUM AND EGRR MODELS CONTINUE TO INDICATE AN EASTWARD TRACK THROUGH THE ENTIRE FORECAST, MOVING THE SYSTEM INTO THE CORAL SEA BY TAU 72. THE LARGE AMOUNT OF UNCERTAINTY IN THE MODELS LENDS LOW CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 231800Z IS 34 FEET. NEXT WARNINGS AT 240300Z, 240900Z, 241500Z AND 242100Z. https://icons.wunderground.com/data/...01816_5day.gif

ANIMATED MULTISPECTRAL IMAGERY (MSI) SHOWS THAT THE CONVECTIVE SIGNATURE ASSOCIATED WITH TC NORA WEAKENED THROUGH THE 0000Z HOUR, WITH ONLY A VERY WEAK, RAGGED EYE FEATURE EVIDENT IN THE MSI. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON ANALYSIS OF THE MSI, AND RADAR FIX DATA FROM THE WEIPA RADAR SITE. A 232207Z AMSU-B 89 GHZ MICROWAVE IMAGE CONFIRMED THAT DEEP CONVECTION WAS LIMITED AT THAT TIME TO THE NORTHWEST QUADRANT, WITH THE EYEWALL BEING OPEN TOWARDS THE SOUTHEAST. THE INITIAL INTENSITY HAS BEEN LOWERED TO 90 KNOTS FOR THIS WARNING, BASED ON SUBJECTIVE DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM T4.5 (77 KNOTS) TO T5.0 (90 KNOTS) AND AUTOMATED INTENSITY GUIDANCE OF T4.8 (84 KNOTS), HEDGED SLIGHTLY HIGHER DUE TO AN INCREASING TREND EVIDENT AT THE TIME OF THE FIX. TC 16P CONTINUES TRACKING SOUTHEASTWARD OVER THE PAST SIX HOURS ALONG THE WESTERN PERIPHERY OF A NEAR EQUATORIAL RIDGE (NER) CENTERED OVER EASTERN NEW GUINEA, THOUGH THE TRACK IS SOMEWHAT FLATTER THAN ORIGINAL FORECAST, WITH A STRONGER EASTWARD COMPONENT THROUGH THE 00Z HOUR. AS PREVIOUSLY MENTIONED INTENSITY HAS DECREASED SLIGHTLY BUT IS ON AN INCREASING TREND. TC 16P IS FORECAST TO CONTINUE TRACKING SOUTHEASTWARD THEN SOUTHWARD UNDER THE STEERING INFLUENCE OF THE NER OVER THE NEXT 36 HOURS. AFTER TAU 36, TC NORA IS EXPECTED TO SLOW SIGNIFICANTLY AS IT ENTERS A WEAK STEERING ENVIRONMENT ASSOCIATED WITH AN UPPER-LEVEL COL AREA BETWEEN THE NER, A DEVELOPING STR TO THE WEST-SOUTHWEST AND THE EQUATORWARD END OF A MID-LATITUDE TROF TO THE SOUTH, BECOMING NEARLY QUASI-STATIONARY IN THE SOUTHEAST CORNER OF THE GULF OF CARPENTARIA THROUGH TAU 72. IN THE EXTENDED TAUS, TC 16P WILL ACCELERATE WESTWARD AS THE STR BECOMES THE PRIMARY STEERING MECHANISM THROUGH THE REMAINDER OF THE FORECAST. WHILE INITIAL INTENSITY HAS DECREASED, BY THE 00Z HOUR, INDICATIONS OF STRENGTHENING WERE ALREADY BECOMING EVIDENT, AND SO A SHORT PERIOD OF ADDITIONAL INTENSIFICATION IS FORECAST THROUGH TAU 12, PEAKING AT 95 KNOTS, AS THE SYSTEM PASSES OVER VERY WARM WATER WITH LOW TO MODERATE VWS AND IMPROVED UPPER-LEVEL OUTFLOW. AFTER TAU 12 AND THROUGH TAU 36 SLOW AND STEADY WEAKENING IS EXPECTED AS THE UPPER-LEVEL FLOW PATTERN BECOMES LESS FAVORABLE AND THE SYSTEM INTERACTS WITH LAND. AFTER TAU 36, AS LAND INTERACTION AND CONVERGENCE ALOFT COMBINE, TC 16P WILL EXPERIENCE MORE RAPID WEAKENING. THE SYSTEM IS FORECAST TO MAKE LANDFALL IN THE SOUTH GULF OF CARPENTARIA BEFORE TAU 96 AND WILL RAPIDLY DISSIPATE OVER LAND BY TAU 120. AVAILABLE MODEL GUIDANCE IS BECOMING INCREASINGLY UNCERTAIN, WITH THREE POTENTIAL SCENARIOS. THE AFUM AND EGRR MODELS CONTINUE TO SHOW THE SYSTEM TRACKING EASTWARD INTO THE CORAL SEA, WHILE THE ECMWF AND ENSEMBLE TRACKING THE SYSTEM FURTHER WEST AND NORTH, MAKING LANDFALL IN THE WESTERN GULF. THE REMAINDER OF THE CONSENSUS MEMBERS ARE GENERALLY IN AGREEMENT WITH THE JTWC FORECAST, WHICH LIES WEST OF THE MULTI-MODEL CONSENSUS TRACK. DUE TO THE LARGE AMOUNT OF UNCERTAINTY IN THE MODELS, THERE IS LOW CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 240000Z IS 28 FEET. NEXT WARNINGS AT 240900Z, 241500Z, 242100Z AND 250300Z. https://icons.wunderground.com/data/...01816_5day.gif

TROPICAL CYCLONE 16P (NORA), LOCATED APPROXIMATELY 297 NM WEST- NORTHWEST OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. ANIMATED EIR SHOWS THE EASTERN FLANK HAS BEGUN TO ERODE AS THE SYSTEM INTERACTED WITH CAPE YORK PENINSULA; HOWEVER, CONVECTIVE BANDS REMAINED RELATIVELY DEEP AND TIGHTLY-WRAPPED INTO A WELL-DEFINED LLC. THE INITIAL POSITION IS BASED WITH HIGH CONFIDENCE ON A CIRCULATION FEATURE IN THE COMPOSITE RADAR LOOP FROM WEIPA. THE INITIAL INTENSITY IS BASED ON AN OVERALL ASSESSMENT OF AGENCY DVORAK ESTIMATES AND REFLECTS THE SLIGHTLY WEAKENED CONVECTIVE SIGNATURE OF 16P. UPPER LEVEL ANALYSIS INDICATES THE CYCLONE IS TRACKING IN THE GULF OF CARPENTARIA ALONG THE SOUTHWEST PERIPHERY OF THE NER TO THE NORTHEAST IN AN AREA OF MODERATE 15-KNOT NORTHERLY VWS BUT STRONG POLEWARD OUTFLOW. SSTS IN THE GULF ARE VERY CONDUCIVE AT 30-31C. TC NORA IS IMMINENTLY EXPECTED TO MAKE LANDFALL AND TRACK MORE SOUTHWARD ALONG THE WESTERN COASTAL AREAS OF CAPE YORK PENINSULA AS THE NER BUILDS. AFTER TAU 24, THE STR ANCHORED OVER WESTERN CENTRAL AUSTRALIA WILL BUILD AND COMPETE FOR STEERING, CAUSING TC 16P TO BECOME QS. THE INITIAL LAND INTERACTION WILL GRADUALLY WEAKEN TC 16P, THEN AFTER TAU 12, VWS IS EXPECTED TO INCREASE AND, AS THE CYCLONE TRACKS FURTHER INLAND, WILL CAUSE A MORE RAPID DECAY. BY TAU 48, THE SYSTEM WILL DISSIPATE OVER LAND SOUTH OF KOWANYAMA. THE MAJORITY OF THE NUMERIC GUIDANCE ARE IN UNISON WITH THE TRACK OUTLINED ABOVE WITH AFUM AS THE SOLE EASTWARD OUTLIER. THE JTWC TRACK FORECAST IS LAID JUST WEST OF CONSENSUS TO OFFSET THE AFUM SOLUTION. IN VIEW OF THIS AND THE UNCERTAINTY OF A QS MOTION, THERE IS OVERALL LOW CONFIDENCE IN THE JTWC TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 241200Z IS 24 FEET. NEXT WARNINGS AT 242100Z, 250300Z, 250900Z AND 251500Z. https://icons.wunderground.com/data/...01816_5day.gif

TROPICAL CYCLONE 16P (NORA), LOCATED APPROXIMATELY 245 NM WEST- NORTHWEST OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS THE SYSTEM IS WEAKENING DUE TO EXTENSIVE INTERACTION WITH THE CAPE YORK PENINSULA. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON A CIRCULATION FEATURE EVIDENT IN THE COMPOSITE RADAR LOOP FROM THE AUSTRALIAN BUREAU OF METEOROLOGY. THE INITIAL INTENSITY OF 65 KNOTS IS BASED ON THE WEAKENING NATURE OF THE SYSTEM AND IS ABOVE AREA OBSERVATIONS THAT ARE DISPLACED FROM THE CIRCULATION CENTER AND TERRAIN INHIBITED. UPPER LEVEL ANALYSIS INDICATES THE SYSTEM HAS STRONG POLEWARD OUTFLOW CHANNEL. ENVIRONMENTAL ANALYSIS SHOWS THAT SYSTEM IS IN AN AREA OF MODERATE (15-20 KNOT) VERTICAL WIND SHEAR AND IS CURRENTLY TRACKING OVER LAND. TC NORA WILL CONTINUE TO TRACK SOUTHERLY AS A STR ANCHORED OVER WESTERN CENTRAL AUSTRALIA WILL BUILD AND COMPETE FOR STEERING, CAUSING THE SYSTEM TO BECOME QUASI-STATIONARY. LAND INTERACTION AND INCREASING VERTICAL WIND SHEAR WILL RAPIDLY WEAKEN TC 16P WITH DISSIPATION BY TAU 48, SOUTH OF KOWANYAMA. AVAILABLE DYNAMIC MODEL GUIDANCE IS IN GENERALLY GOOD AGREEMENT WITH THE OVERALL TRACK DIRECTION HOWEVER THERE IS A SUBSTANTIAL SPREAD AFTER TAU 24. IN VIEW OF THIS AND THE UNCERTAINTY OF A QUASI-STATIONARY MOTION, THERE IS OVERALL LOW CONFIDENCE IN THE JTWC TRACK FORECAST. NEXT WARNINGS AT 250300Z, 250900Z, 251500Z AND 252100Z. REFER TO TROPICAL CYCLONE 17P (SEVENTEEN) WARNINGS (WTPS32 PGTW) FOR SIX- HOURLY UPDATES. https://icons.wunderground.com/data/...01816_5day.gif
