JTWC10/0200Z評級Low

(1) AN AREA OF CONVECTION (INVEST 92W) HAS PERSISTED NEAR
10.9N 171.0E, APPROXIMATELY 235 NM NORTHEAST OF KWAJALEIN ATOLL.
ANIMATED MULTI SPECTRAL IMAGERY DEPICTS A BROAD, ELONGATED LOW
LEVEL CIRCULATION (LLC) WITH PERSISTENT CONVECTION TO THE WEST OF
THE LLC PERIPHERY AND MAXIMUM WINDS DISPLACED FROM THE CENTER. A
092146Z GMI 37GHZ MICROWAVE IMAGE SHOWS FORMATIVE LOW-LEVEL BANDING
FEATURES WRAPPING INTO AN ILL-DEFINED CIRCULATION CENTER.
ENVIRONMENTAL ANALYSIS REVEALS THAT THE SYSTEM IS IN A REGION OF WARM
SEA SURFACE TEMPERATURES (29-30C) AND IS CURRENTLY EXPERIENCING GOOD
DIVERGENCE ALOFT. DEVELOPMENT IS CURRENTLY BEING HAMPERED BY
MODERATE TO HIGH (15-25 KNOTS) VERTICAL WIND SHEAR IN THE VICINITY
OF THE LLC. GLOBAL MODELS AGREE THAT THE SYSTEM WILL GRADUALLY
INTENSIFY AS IT TRACKS TO THE NORTHWEST, REACHING BASIN WARNING
CRITERIA IN THE NEXT 48 TO 72 HOURS.  MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS
UPGRADED TO LOW.

JTWC升格26W,初報強度上望95節

WDPN31 PGTW 111500
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL DEPRESSION 26W (TWENTYSIX)
WARNING NR 01//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
   TROPICAL DEPRESSION 26W (TWENTYSIX), LOCATED APPROXIMATELY 1166
NM EAST OF WFO GUAM, HAS TRACKED WESTWARD AT 16 KNOTS OVER THE PAST
SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS TD 26W
CONTINUES TO IMPROVE IN STRUCTURE WITH EXCELLENT LOW LEVEL BANDING
AND DEEP CONVECTION, MAINLY TO THE WEST OF THE LOW LEVEL CIRCULATION
CENTER (LLCC). THE INITIAL POSITION IS PLACED WITH GOOD CONFIDENCE
BASED ON A 110946Z METOP-C ASCAT PASS SHOWING 25 KNOT WIND BARBS TO
THE NORTH AND SOUTH OF THE LLCC. THE INITIAL INTENSITY OF 25 KNOTS
IS BASED ON MULTI-AGENCY DVORAK INTENSITY ESTIMATE OF T1.0-1.5 (25
KNOTS) AND THE AFOREMENTIONED ASCAT PASS. ENVIRONMENTAL ANALYSIS
SHOWS TD 26W IS EXPERIENCING MODERATELY FAVORABLE VERTICAL WIND
SHEAR (15-20 KNOTS) ALONG WITH GOOD UPPER LEVEL DIVERGENCE. SEA
SURFACE TEMPERATURES ARE ALSO FAVORABLE (29-30 DEGREES CELSIUS) FOR
CONTINUED DEVELOPMENT. TD 26W IS TRACKING WESTWARD UNDER THE
INFLUENCE OF THE WEST TO EAST ORIENTATED SUBTROPICAL RIDGE (STR)
LOCATED TO THE NORTH.
3. FORECAST REASONING.
   A. THIS IS THE INITIAL PROGNOSTIC REASONING AND SETS THE FORECAST
PHILOSOPHY.
   B. TD 26W WILL CONTINUE TO TRACK TO THE NORTHWEST UNDER THE
INFLUENCE OF THE AFOREMENTIONED STR. THE STR WILL BE THE PRIMARY
STEERING FEATURE THROUGH TAU 72. UPPER LEVEL OUTFLOW AND SEA SURFACE
TEMPERATURES ARE ALL CONDUCIVE FOR CONTINUED INTENSIFICATION. THE
POTENTIAL FOR RAPID INTENSIFICATION IS CURRENTLY HAMPERED BY
MODERATE TO HIGH VWS THROUGHOUT THE FORECAST TRACK.
AS A RESULT, TD 26W IS CURRENTLY EXPECTED TO REACH AN INTENSITY OF
75 KNOTS BY TAU 72. DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT WITH
A MODEL SPREAD OF 120 NM BY TAU 72. THEREFORE, THERE IS HIGH
CONFIDENCE IN THIS PORTION OF THE JTWC FORECAST TRACK.
   C. AFTER TAU 72, THE STR LOCATED TO THE NORTH WILL ERODE AS A
RESULT OF AN APPROACHING MID-LATITUDE TROUGH. TD 26W IS CURRENTLY
EXPECTED TO MOVE THROUGH A NEWLY FORMED COL AS IT APPROACHES THE STR
AXIS AROUND TAU 96. VERTICAL WIND SHEAR IS EXPECTED TO INCREASE TO
HIGH (25-35 KNOTS) DURING THIS TIME PERIOD, LIMITING PEAK INTENISTY
TO 95 KNOTS. DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT WITH A
TRACK SPREAD OF 170 NM BY TAU 120. HOWEVER, RECURVE TIMING REMAINS
UNCERTAIN AROUND THE END OF THE FORECAST. THEREFORE, THERE IS
OVERALL FAIR CONFIDENCE IN THIS PORTION OF THE JTWC FORECAST TRACK,
WHICH IS PLACED NEAR THE MULTI-MODEL CONSENSUS. THERE IS A LARGE
SPREAD IN INTENSITY GUIDANCE, ESPECIALLY WHEN SHEAR IS EXPECTED TO
PEAK. THE JTWC INTENSITY FORECAST IS PLACED NEAR THE CONSENSUS WITH
POOR CONFIDENCE.//
