已經降到35kts 不支持發展
預估很快就要減弱消散
雖然指向夏威夷不過大概到不了了吧

上望50KT
目標朝向夏威夷

不看好跨洋

1. The Central Pacific Hurricane Center will be initiating advisories at 11 am HST on newly formed tropical depression One-C, located about 1300 miles east southeast of Honolulu.

CPHC將在三小時之後發布01C熱帶低壓首報

CPHC從Low直接提升到High

An area of low pressure located about 1000 miles east southeast of the Big Island of Hawaii has been moving west northwest at less than 10 mph. An area of showers and thunderstorms associated with the disturbance has become better organized overnight. Environmental conditions appear to be conducive for development, and a tropical depression may be forming. Advisories may be initiated later today for this system if current trends continue. After 24 to 36 hours, upper-level winds are expected to become unfavorable for tropical cyclone development.

* Formation chance through 48 hours, high, 80 percent.

JTWC也在稍早發出TCFA

FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 180
NM EITHER SIDE OF A LINE FROM 11.3N 140.7W TO 15.2N 145.9W WITHIN THE
NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF
NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS IN THE AREA
ARE ESTIMATED TO BE 20 TO 25 KNOTS. METSAT IMAGERY AT 171131Z
INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 11.9N 141.5W. THE
SYSTEM IS MOVING NORTHWESTWARD AT 06 KNOTS.
2. REMARKS: AN AREA OF CONVECTION HAS PERSISTED NEAR 11.9N 141.5W,
APPROXIMATELY 910 NM EAST-SOUTHEAST OF HILO, HAWAII. ANIMATED
ENHANCED INFRARED SATELLITE IMAGERY DEPICTS IMPROVED ORGANIZATION OF
DEEP CENTRALIZED CONVECTION OVER A CONSOLIDATING LOW-LEVEL
CIRCULATION CENTER (LLCC). A RECENT 171059Z TRMM MICROWAVE PASS
INDICATES THE FORMATIVE BANDING IS BEGINNING TO WRAP TOWARDS THE
LLCC. UPPER LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT
CHARACTERIZED BY LOW VERTICAL WIND SHEAR AND GOOD DIVERGENCE ALOFT.
SEA SURFACE TEMPERATURES IN THE AREA ARE FAVORABLE FOR CONTINUED
DEVELOPMENT. DYNAMIC MODELS INDICATE A WEST-NORTHWEST TRACK TOWARDS
THE ISLANDS OF HAWAII AS THE CYCLONE DEVELOPS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. DUE TO THE INCREASED
CONSOLIDATION OF THE LLCC, THE POTENTIAL FOR DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.

整體對流大幅度改善
螺旋性明顯
成為中太首旋機率相當高...

這根本就是原來的90E
不算是新擾吧...

已證實此擾為原90E重新編號過後的
此帖將併入90E
NRL居然會改編號 @@ 我是第一次看過...
So... 這該算是中太首擾嗎?@@
