SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 22W (HAGUPIT) WARNING
NR 39//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 22W (HAGUPIT), LOCATED APPROXIMATELY 533 NM
EAST-NORTHEAST OF HO CHI MINH CITY, VIETNAM, HAS TRACKED WESTWARD AT
09 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY (EIR) DEPICTS A SYMMETRIC AREA OF DEEP CONVECTION
PERSISTING OVER A PARTIALLY-EXPOSED LOW-LEVEL CIRCULATION CENTER
(LLCC). A 101213Z SSMIS 91 GHZ IMAGE SHOWS CURVED DEEP CONVECTIVE
BANDING OVER THE NORTHERN SEMI-CIRCLE, JUST NORTH OF THE CENTER, AND
SHALLOW BANDING ELSEWHERE. THE CURRENT POSITION IS BASED ON THE EIR
AND SSMIS IMAGERY WITH FAIR CONFIDENCE. THE INITIAL INTENSITY IS
ASSESSED AT 40 KNOTS, HEDGED SLIGHTLY LOWER THAN THE T3.0 DVORAK
ESTIMATES, BASED ON RECENT SCATTEROMETER DATA SHOWING 35 TO 40 KNOT
WINDS OVER THE NORTHERN QUADRANT. UPPER-LEVEL ANALYSIS INDICATES A
FAVORABLE ENVIRONMENT WITH MODERATE (15-20 KNOTS) VERTICAL WIND
SHEAR OFFSET BY VIGOROUS POLEWARD OUTFLOW INTO THE STRONG WESTERLY
FLOW TO THE NORTH. TS 22W IS CURRENTLY TRACKING ALONG THE
SOUTHWESTERN PERIPHERY OF A SUBTROPICAL RIDGE (STR).
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TS HAGUPIT IS FORECAST TO TRACK WEST-SOUTHWESTWARD THROUGH THE
FORECAST PERIOD UNDER THE INFLUENCE OF LOW-LEVEL NORTHEASTERLY FLOW.
THE SYSTEM IS EXPECTED TO MAKE LANDFALL OVER SOUTHERN VIETNAM BY TAU
30 AND SHOULD DISSIPATE BY TAU 48. TS 22W IS FORECAST TO WEAKEN AS
IT INTERACTS WITH THE COOLER, DRIER AIR ASSOCIATED WITH THE
NORTHEASTERLY SURGE BEYOND TAU 12. DYNAMIC MODEL GUIDANCE REMAINS IN
TIGHT AGREEMENT, LENDING HIGH CONFIDENCE TO THE JTWC FORECAST TRACK,
WHICH IS POSITIONED CLOSE TO THE MULTI-MODEL CONSENSUS.//

2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 22W (HAGUPIT), LOCATED APPROXIMATELY 408 NM
EAST-NORTHEAST OF HO CHI MINH CITY, VIETNAM, HAS TRACKED WEST-
SOUTHWESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A SMALL CONVECTIVE
CELL OVER A NEARLY FULLY EXPOSED LOW-LEVEL CIRCULATION CENTER
(LLCC), WITH THE REMAINING DEEP CONVECTION NOW DISPLACED
SIGNIFICANTLY EASTWARD. A 102101Z SSMIS 85 GHZ IMAGE INDICATES THIS
DISPLACEMENT OF DEEP CONVECTION TO BE APPROXIMATELY 80 NM. THE
CURRENT POSITION IS BASED ON THE LLCC IN MSI AND THE PGTW FIX WITH
GOOD CONFIDENCE. THE INITIAL INTENSITY WAS MAINTAINED AT 35 KNOTS AS
THE SYSTEM GRADUALLY WINDS DOWN. UPPER-LEVEL ANALYSIS INDICATES TS
22W STILL HAS FAVORABLE POLEWARD OUTFLOW, HOWEVER, IT IS NOT
SUFFICIENT TO OVERCOME UPPER LEVEL SUBSIDENCE IN THE SOUTHEASTERN
QUADRANT AND INCREASING VERTICAL WIND SHEAR (VWS) AS LOW LEVEL
NORTHEASTERLY WINDS ARE NOW COMPLETELY OUT OF PHASE WITH THE UPPER
LEVEL. TS 22W IS CURRENTLY TRACKING ALONG THE SOUTHWESTERN PERIPHERY
OF A SUBTROPICAL RIDGE (STR).
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TS HAGUPIT IS FORECAST TO TRACK WEST-SOUTHWESTWARD THROUGH THE
FORECAST PERIOD UNDER THE INFLUENCE OF LOW-LEVEL NORTHEASTERLY FLOW.
THE SYSTEM WILL CONTINUE TO WEAKEN IN RESPONSE TO MORE STABLE AIR
AND CONTINUED VWS ASSOCIATED WITH THE NORTHEASTERLY SURGE. TS 22W IS
EXPECTED TO MAKE LANDFALL OVER SOUTHERN VIETNAM BEFORE TAU 24 AND
SHOULD DISSIPATE OVER LAND BY TAU 36. DYNAMIC MODEL GUIDANCE REMAINS
IN TIGHT AGREEMENT WITH LANDFALL AND DISSIPATION, EXCEPT FOR HWRF
WHICH CALLS FOR A MORE SOUTHERLY, OVER-WATER TRACK. THE GFS ENSEMBLE
MEAN SOLUTION DENOTES LANDFALL, HOWEVER THE SPREAD OF THE MEMBERS
REFLECTS THE POSSIBILITY THAT TS 22W COULD SKIRT THE VIETNAMESE
COAST. GIVEN THE OVERALL GOOD MODEL AGREEMENT, THERE IS HIGH
CONFIDENCE IN THE JTWC FORECAST TRACK, WHICH IS POSITIONED CLOSE TO

2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL DEPRESSION (TD) 22W (HAGUPIT), LOCATED APPROXIMATELY 314
NM EAST-NORTHEAST OF HO CHI MINH CITY, VIETNAM, HAS TRACKED WESTWARD
AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
(EIR) SATELLITE IMAGERY SHOWS THE FLARING CONVECTION SHEARED TO THE
NORTHEAST OVER THE LOW-LEVEL CIRCULATION CENTER. A SERIES OF
MICROWAVE IMAGERY INCLUDING AN 111201Z SSMIS MICROWAVE IMAGE REVEALS
SLIGHTLY INCREASED DEEP CENTRAL CONVECTION OVER THE PAST SIX HOURS.
THE CURRENT POSITION IS BASED ON THE EIR ANIMATION, SSMIS IMAGE, AND
PGTW FIX WITH HIGH CONFIDENCE. THE INITIAL INTENSITY OF 30 KNOTS IS
BASED ON MATCHING DVORAK CURRENT INTENSITY ESTIMATES FROM PGTW AND
KNES. UPPER-LEVEL ANALYSIS INDICATES THE SYSTEM REMAINS IN AN AREA
OF MODERATE (10 TO 20 KNOT) VERTICAL WIND SHEAR OFFSET BY GOOD
POLEWARD OUTFLOW. TD 22W IS CURRENTLY TRACKING ALONG THE
SOUTHEASTERN PERIPHERY OF A SUBTROPICAL RIDGE (STR).

17 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE

MOVED OUT FROM UNDER THE DEEP CONVECTION AND IS QUICKLY UNRAVELING,

HAGUPIT KILLED ONLY 19 PEOPLE, and bringing only 3-4 billion PHP in damages compared to Bopha and Haiyan which caused 1,000+ deaths and damages of more than 40 billion PHP.
Drastic improvement, then. ![Smile :)](./images/smilies/icon_smile.gif)
