Next name on the list is EWINIAR....submitted by Micronesia which means chuuk traditional god...

it's been used 2 times...2000 and 2006...both storms became typhoons peaking at 75 knots and 130 knots...

can this year's ewiniar become the 3rd straight typhoon?

AN AREA OF CONVECTION HAS PERSISTED NEAR 14.1N 140.7E,
APPROXIMATELY 250 NM WEST OF ANDERSON AFB, GUAM. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS AN AREA OF CONVERGENT FLOW
WEST OF A BROAD, WEAK CIRCULATION ASSOCIATED WITH THE MONSOON
TROUGH. A PARTIAL 221823Z AMSU 89GHZ MICROWAVE IMAGE DEPICTS AN AREA
OF VERY POORLY ORGANIZED CONVECTION. UPPER LEVEL ANALYSIS INDICATES
THE AREA IS UNDER MODERATE (15-20 KNOTS) VERTICAL WIND SHEAR FROM
THE WEST, WHICH IS EVIDENT IN THE MSI DUE TO THE LACK OF CONVECTION
TO THE NORTHWEST OF THE SYSTEM. ANIMATED WATER VAPOR IMAGERY FURTHER
INDICATES THERE IS GOOD DIVERGENT OUTFLOW DUE TO A TUTT CELL LOCATED
AT APPROXIMATELY 25N 160E. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1007 MB. DUE TO THE LESS THAN FAVORABLE UPPER LEVEL
ENVIRONMENT THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 14.1N
140.7E, IS NOW LOCATED NEAR 15.9N 138.3E, APPROXIMATELY 405 NM WEST-
NORTHWEST OF ANDERSEN AFB, GUAM. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS AN EXPOSED, BROAD LOW-LEVEL CIRCULATION CENTER
(LLCC) WITH DEEP CONVECTION SHEARED EAST OF THE CENTER. A 222255Z
SSMIS 37GHZ IMAGE, HOWEVER, INDICATES IMPROVED FORMATIVE CONVECTIVE
BANDING WRAPPING INTO A BROAD LLCC AND STRONG BANDING OVER THE
SOUTHEAST QUADRANT DUE TO CONFLUENT WESTERLY FLOW. A 230002Z PARTIAL
ASCAT IMAGE DEPICTS SHARP TROUGHING WITH AN ELONGATED CIRCULATION
AND 25- TO 30-KNOT SOUTHWESTERLY WINDS DISPLACED WELL SOUTH AND
SOUTHEAST OF THE SYSTEM. UPPER-LEVEL ANALYSIS SHOWS THAT VERTICAL
WIND SHEAR (VWS) HAS DECREASED OVER THE PAST 24 HOURS AND IS
CURRENTLY MODERATE (15 TO 20 KNOTS) WESTERLY VWS. ANIMATED WATER
VAPOR IMAGERY INDICATES IMPROVED POLEWARD OUTFLOW INTO A TUTT CELL
NEAR 25N 167E. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15
TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006
MB. BASED ON THE IMPROVING ENVIRONMENT AND STRUCTURE AS WELL AS
MODEL DEVELOPMENT IN THE NEXT 48 HOURS, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.

OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS
A SLOWLY CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC)
WITH DEEP CONVECTIVE BANDING OVER THE EASTERN SEMI-CIRCLE WRAPPING
INTO THE EAST QUADRANT. A 241227Z METOP-A IMAGE INDICATES A SLIGHTLY
ELONGATED BUT IMPROVING LLCC WITH TIGHTLY-CURVED SHALLOW CONVECTIVE
BANDING OVER THE WESTERN SEMI-CIRCLE. AS DEPICTED IN ANIMATED WATER
VAPOR IMAGERY AND RECENT UW-CIMSS SHEAR PRODUCTS, THE UPPER-LEVEL
ENVIRONMENT HAS REMAINED MARGINAL DUE TO MODERATE, WESTERLY VERTICAL
WIND SHEAR (VWS) ASSOCIATED WITH THE OUTFLOW FROM STY 18W. THE
INITIAL INTENSITY IS ASSESSED AT 35 KNOTS, WHICH IS SLIGHTLY HIGHER
THAN THE DVORAK ESTIMATES OF 30 KNOTS, BASED ON A 241227Z ASCAT
IMAGE SHOWING 35-KNOT WINDS OVER THE EASTERN SEMI-CIRCLE. THE
INITIAL POSITION IS BASED ON RECENT FIXES AND THE 241227Z METOP-A
IMAGE WITH FAIR CONFIDENCE. TS 19W IS CURRENTLY TRACKING POLEWARD
ALONG THE WESTERN PERIPHERY OF THE LOW- TO MID-LEVEL SUBTROPICAL
RIDGE (STR).
3. FORECAST REASONING.
A. THERE IS NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE
PREVIOUS PROGNOSTIC REASONING MESSAGE.
B. TS 19W IS FORECAST TO TRACK GENERALLY NORTH-NORTHEASTWARD
THROUGH THE PERIOD AND SHOULD INTENSIFY TO A PEAK INTENSITY NEAR 45
KNOTS BY TAU 24 DUE TO INCREASING POLEWARD OUTFLOW ASSOCIATED WITH
THE APPROACHING MIDLATITUDE SHORTWAVE TROUGH AND DECREASING VWS.
AFTER TAU 48, TS 19W IS FORECAST TO ENCOUNTER AN INCREASINGLY
HOSTILE ENVIRONMENT AS IT TRACKS ALONG AND INTO THE LEADING EDGE OF
THE AFOREMENTIONED SHORTWAVE TROUGH. THE SYSTEM MAY ENCOUNTER WEAK
BAROCLINICITY ASSOCIATED WITH THE SUBTROPICAL TROUGH; HOWEVER, THERE
IS NO EVIDENCE THAT TS 19W WILL UNDERGO EXTRA-TROPICAL TRANSITION
UNTIL WELL AFTER THE FORECAST PERIOD. DYNAMIC MODEL GUIDANCE IS IN
FAIR AGREEMENT, THEREFORE, THE JTWC TRACK IS POSITIONED CLOSE TO THE
MULTI-MODEL CONSENSUS.
C. IN THE EXTENDED TAUS, TS 19W IS FORECAST TO WEAKEN RAPIDLY DUE
TO COOLER SST AND INCREASING VWS AND WILL ACCELERATE NORTHEASTWARD.
DYNAMIC GUIDANCE REMAINS IN FAIR AGREEMENT. DUE TO THE PRESENCE OF
STRONG WESTERLY FLOW OVER HONSHU, TS 19W IS NOT EXPECTED TO IMPACT
THE KANTO PLAIN AND SHOULD ALSO WEAKEN RAPIDLY SOUTHEAST AND EAST OF
HONSHU. THERE IS HIGH CONFIDENCE IN THE FORECAST TRACK.//

WDPN32 PGTW 250300
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 19W (EWINIAR)
WARNING NR 05//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 19W (EWINIAR), LOCATED APPROXIMATELY 285 NM
SOUTHWEST OF IWO-TO, JAPAN, HAS TRACKED NORTH-NORTHWESTWARD AT 07
KNOTS OVER THE PAST SIX HOURS. THE CURRENT POSITION IS BASED, WITH
MODERATE CONFIDENCE, ON RECENT SATELLITE FIXES FROM PGTW AND RJTD
AND A 242057Z SSMIS IMAGE. THE CURRENT INTENSITY OF 40 KNOTS IS
BASED ON A DVORAK T-NUMBER ESTIMATE OF 2.5 FROM PGTW AND OBJECTIVE
FIXES FROM CIMSS AND CIRA INDICATING AN INTENSITY OF ABOUT 40 KNOTS.
TS 19W IS TRACKING POLEWARD ALONG THE WESTERN PERIPHERY OF A
SUBTROPICAL STEERING RIDGE TO THE EAST TOWARD THE BASED OF SHORTWAVE
TROUGH EXTENDING SOUTHWESTWARD FROM THE SEA OF JAPAN ACROSS THE EAST
CHINA SEA. PERSISTENT EASTERLY VERTICAL WIND SHEAR ASSOCIATED WITH
THE UPPER-LEVEL OUTFLOW FROM STY 18W CONTINUES TO CONFINE THE
DEEPEST CONVECTION TO THE EASTERN PERIPHERY OF THE PARTIALLY-EXPOSED
LOW-LEVEL CIRCULATION CENTER.
3. FORECAST REASONING.
A. NO CHANGE IN THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TS 19W IS FORECAST TO TRACK GENERALLY NORTHEASTWARD OVER
THE NEXT 24 HOURS UNDER THE CONTINUED STEERING INFLUENCE OF THE
SUBTROPICAL RIDGE TO THE EAST. THEREAFTER, THE SYSTEM WILL MOVE
POLEWARD AS IT INTERACTS WITH THE APPROACHING SHORTWAVE TROUGH TO
THE WEST. SLOW INTENSIFICATION IS EXPECTED OVER THE NEXT 48 HOURS
DUE TO STRONG OUTFLOW ALOFT, WHICH WILL LIKELY IMPROVE AS THE SYSTEM
BEGINS TO INTERACT WITH THE APPROACHING TROUGH, AND AN ANTICIPATED
PERIOD OF DECREASING VERTICAL WIND SHEAR. AS THE APPROACHING TROUGH
MOVES OVER TS 19W, INCREASING VERTICAL WIND SHEAR AND SUPPRESSED
OUTFLOW WILL HALT THE INTENSIFICATION TREND. THE AVAILABLE NUMERICAL
MODEL GUIDANCE IS IN FAIR, BUT IMPROVING, AGREEMENT WITH THE CURRENT
TRACK FORECAST THROUGH TAU 72.
C. IN THE EXTENDED PERIOD, TS 19W WILL ROUND THE STEERING RIDGE
AXIS AND ACCELERATE POLEWARD TOWARD THE MIDLATITUDE WESTERLY FLOW
PATTERN. DURING THIS TIME, INCREASING VERTICAL WIND SHEAR AND
PASSAGE OVER COOLER WATER WILL INDUCE STEADY WEAKENING. TS 19W IS
EXPECTED TO REMAIN EQUATORWARD OF A BAROCLINIC BOUNDARY UNTIL
FORECAST TAU 120, WHEN EXTRATROPICAL TRANSITION IS EXPECTED TO
BEGIN. THE CURRENT TRACK FORECAST LIES CLOSE TO THE NUMERICAL MODEL
CONSENSUS. THERE IS HIGH CONFIDENCE IN THE CURRENT FORECAST TRACK.//

1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 19W (EWINIAR), LOCATED APPROXIMATELY 130 NM
WEST-SOUTHWEST OF IWO-TO, JAPAN, HAS TRACKED NORTH-NORTHEASTWARD AT
12 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED (IR) SATELLITE
IMAGERY SHOWS THE LOW LEVEL CIRCULATION CENTER REMAINS PARTIALLY
DISPLACED FROM THE MAIN CONVECTION DUE TO MODERATE (15-20 KNOT)
SOUTHWESTERLY VERTICAL WIND SHEAR (VWS). HOWEVER, DESPITE THE VWS,
THE CENTRAL CONVECTION HAS DEEPENED, PRIMARILY FUELED BY STRONG
POLEWARD OUTFLOW, AS EVIDENCED ON ANIMATED WATER VAPOR IMAGERY. THE
INITIAL POSITION IS BASED ON THE IR ANIMATION WITH POOR CONFIDENCE.
THE INITIAL INTENSITY IS BASED ON DVORAK ESTIMATES FROM PGTW AND
KNES. UPPER LEVEL ANALYSIS INDICATES THE CYCLONE IS 7 DEGREES
NORTHWEST OF A RIDGE AXIS AND AHEAD OF A SHORTWAVE TROUGH APPROACHING
FROM THE WEST THAT IS CAUSING THE ENHANCED POLEWARD OUTFLOW. TS 19W
IS TRACKING ALONG THE WESTERN PERIPHERY OF A SUBTROPICAL RIDGE (STR)
TO THE EAST.
3. FORECAST REASONING.
A. THERE IS NO CHANGE IN THE FORECAST PHILOSOPHY SINCE THE
PREVIOUS PROGNOSTIC REASONING MESSAGE.
B. TS 19W IS FORECAST TO TRACK MORE NORTHEASTWARD OVER THE NEXT 24
HOURS AS THE STEERING STR WEAKENS WITH THE APPROACH OF THE
AFOREMENTIONED TROUGH. AFTER TAU 24, THE SYSTEM WILL REGAIN A MORE
POLEWARD STORM MOTION AS THE STR REBUILDS BEHIND THE SHORTWAVE
TROUGH. SLOW INTENSIFICATION IS EXPECTED DURING THIS PORTION OF THE
FORECAST AS THE STRONG OUTFLOW PERSISTS AND THE VWS RELAXES SLIGHTLY
AS THE STORM MOTION BECOMES MORE IN PHASE WITH THE UPPER LEVEL FLOW.
C. IN THE EXTENDED PERIOD, TS 19W WILL BEGIN TO ACCELERATE
NORTHEASTWARD AS THE STR AGAIN WEAKENS WITH THE APPROACH OF A
SECONDARY SHORTWAVE TROUGH. THIS WILL COINCIDE WITH THE SYSTEM
UNDERGOING EXTRA-TROPICAL TRANSITION. THE SYSTEM WILL BECOME A
COLD-CORE LOW BY TAU 12O. INCREASING VWS AND PASSAGE OVER COOLER
WATER WILL ALSO INDUCE STEADY WEAKENING. THE CURRENT TRACK FORECAST
LIES CLOSE TO THE NUMERICAL MODEL CONSENSUS. THERE IS HIGH CONFIDENCE
IN ALL TAUS OF THE CURRENT FORECAST TRACK. //
