WDPN31 PGTW 210900
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL DEPRESSION 30W (THIRTY)
WARNING NR 001//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL DEPRESSION 30W (THIRTY), LOCATED APPROXIMATELY 276 NM
SOUTHEAST OF YAP, HAS TRACKED WEST-NORTHWESTWARD AT 12 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS
FLARING CENTRAL CONVECTION EMANATING FROM THE LOW LEVEL CIRCULATION
CENTER (LLCC) WITH WEAK AND FRAGMENTED BANDING ON THE NORTHERN
PERIPHERY. THE INITIAL INTENSITY ASSESSMENT OF 25 KNOTS IS BASED ON
A 210032Z METOP-A ASCAT IMAGE AND THE LOWER ENVELOPE OF DVORAK
ESTIMATES RANGING FROM T1.5 TO T2.0 (25 TO 30 KNOTS). ENVIRONMENTAL
CONDITIONS ARE FAVORABLE WITH SSTS NEAR 30 CELSIUS, LOW VERTICAL
WIND SHEAR, AND MODERATE DIFFLUENCE ALOFT. CURRENTLY TD 30W IS
TRACKING NORTHWESTWARD ALONG THE SOUTHERN PERIPHERY OF A DEEP-
LAYERED SUBTROPICAL RIDGE.
3. FORECAST REASONING.
A. THIS IS THE INITIAL PROGNOSTIC REASONING MESSAGE AND SETS THE
FORECAST PHILOSOPHY ON THIS SYSTEM.
B. TD 30W WILL CONTINUE TO TRACK NORTHWESTWARD ALONG THE STEERING
RIDGE FOR THE REMAINDER OF THE FORECAST. GRADUAL INTENSIFICATION IS
EXPECTED OVER THE NEXT FEW DAYS AS CONDITIONS REMAIN FAVORABLE AND
THE SYSTEM CONSOLIDATES. THE PEAK INTENSITY IS EXPECTED TO REACH 75
KNOTS BY TAU 72.
C. IN THE EXTENDED FORECAST TD 30W WILL MAKE LANDFALL OVER LUZON
AROUND TAU 120 AT OR NEAR ITS PEAK INTENSITY OF 75 KNOTS. DYNAMIC
MODEL GUIDANCE SHOWS GOOD AGREEMENT IN A TRACK NORTHWESTWARD OVER
THE PHILIPPINES. HOWEVER, MESOSCALE MODELS COAMPS-TC AND HWRF SHOW A
TRACK SLIGHTLY POLEWARD FROM THE GROUPING POSSIBLY DUE TO WEAKENING
IN THE STEERING RIDGE. OVERALL THERE IS HIGH CONFIDENCE IN FORECAST
TRACK. //

Peak intensity upped to a Cat 3.

WDPN31 PGTW 212100
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 30W (NOCK-TEN) WARNING
NR 03//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 30W (NOCK-TEN), LOCATED APPROXIMATELY 162 NM
SOUTHEAST OF YAP, HAS TRACKED NORTHWESTWARD AT 12 KNOTS OVER THE
PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS
INCREASED CENTRAL CONVECTION CONSOLIDATING OVER A DEFINED LOW LEVEL
CIRCULATION CENTER, EVIDENT IN A 211229Z ASCAT PASS. A 211941Z GPM
89GHZ MICROWAVE IMAGE SHOWS DEEP FRAGMENTED BANDING WRAPPING
AROUND THE NORTHERN PERIPHERY WITH WEAK CENTRAL CONVECTION. THE
CURRENT POSITION IS BASED ON A LOW REFLECTIVITY CORE IN A 211545Z
AMSR-2 89GHZ MICROWAVE IMAGE WITH GOOD CONFIDENCE. THE INTENSITY HAS
BEEN INCREASED TO 35 KNOTS BASED ON AN ASSESSMENT OF THE
AFOREMENTIONED ASCAT PASS AND IS SUPPORTED BY DVORAK INTENSITY
ESTIMATES OF T2.5 (35 KNOTS) FROM PGTW AND KNES. TS NOCK-TEN IS
LOCATED IN A VERY FAVORABLE ENVIRONMENT WITH LOW (5-10 KNOTS)
VERTICAL WIND SHEAR (VWS), GOOD DIVERGENT OUTFLOW, AND VERY WARM SEA
SURFACE TEMPERATURES. TS 30W IS TRACKING NORTHWESTWARD ALONG THE
SOUTHERN PERIPHERY OF A DEEP-LAYERED SUBTROPICAL RIDGE (STR).
3. FORECAST REASONING.
A. THE PEAK INTENSITY HAS BEEN INCREASED TO 100 KNOTS BASED ON AN
ASSESSMENT OF VERY FAVORABLE ENVIRONMENTAL CONDITIONS OVER THE NEXT
72 HOURS.
B. TS 30W WILL TRACK NORTHWESTWARD ALONG THE SOUTHERN PERIPHERY
OF THE STEERING STR THROUGHOUT THE FORECAST PERIOD. TS NOCK-TEN WILL
CONTINUE TO INTENSIFY UNDER THE VERY FAVORABLE ENVIRONMENTAL
CONDITIONS WITH THE POTENTIAL FOR A PERIOD OF RAPID INTENSIFICATION,
DUE TO HIGH OCEAN HEAT CONTENT, PRIOR TO REACHING THE
EASTERN COAST OF THE PHILIPPINES. DYNAMIC MODEL GUIDANCE IS IN VERY
GOOD AGREEMENT, LENDING TO HIGH CONFIDENCE DURING THIS PORTION OF
THE FORECAST.
C. IN THE EXTENDED FORECAST, TS 30W WILL MAKE LANDFALL OVER
SOUTHERN LUZON JUST AFTER TAU 96. THE SYSTEM SHOULD WEAKEN SLIGHTLY
DUE TO LAND INTERACTION JUST PRIOR TO LANDFALL; HOWEVER, IF THE
TRACK SHIFTS SOUTH OVER THE CENTRAL PHILIPPINES, THE CYCLONE COULD
CONTINUE TO INTENSIFY. ONCE THE SYSTEM EMERGES IN THE SOUTH CHINA
SEA, MODELS DEPICT A COLD SURGE THAT WILL INCREASE THE VWS AND
ADVECT COLD AND RELATIVELY DRY AIR INTO THE SYSTEM. TS 30W WILL TURN
TO THE SOUTH AND WEAKEN UNDER THESE CONDITIONS. DYNAMIC MODEL
GUIDANCE SHOWS A SPREAD ONCE THE CYCLONE REACHES THE SOUTH CHINA SEA
DUE TO COMPETING FLOW AT THE SURFACE AND UPPER LEVELS. DUE TO THIS,
THERE IS LOW CONFIDENCE IN THE EXTENDED PORTION OF THE FORECAST.//

Which would put Manila in the RFQ.
Question is how much further south. worst case scenario is less than >15 kms south.
I remember Durian 2006 was also forecast to make a direct hit at the capital however it stayed well south of the capital - crossed the waters between the province of Batangas and the Island of Mindoro.

^more ensemble members now shows a northward/recurve scenario though, so I wonder if we're gonna see a last minute save here.

WDPN31 PGTW 220900
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 30W (NOCK-TEN) WARNING
NR 05//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 30W (NOCK-TEN), LOCATED APPROXIMATELY 13 NM
WEST-SOUTHWEST OF YAP, HAS TRACKED WEST-NORTHWESTWARD AT 14 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY INDICATES DEEP CONVECTION BUILDING OVER THE LOW-LEVEL
CIRCULATION CENTER (LLCC). A 220711Z GPM COMPOSITE IMAGE SHOWS
MULTIPLE CONVECTIVE BANDS WRAPPING INTO THE LLCC WITH A DEFINED
CENTER POSITIONED JUST TO THE WEST OF YAP, WHICH SUPPORTS THE
CURRENT POSITION WITH GOOD CONFIDENCE. THE CURRENT INTENSITY IS
ASSESSED AT 40 KNOTS BASED ON AN AVERAGE OF DVORAK INTENSITY
ESTIMATES RANGING FROM T2.5 (35 KNOTS) TO T3.0 (45 KNOTS). TS NOCK-
TEN IS LOCATED IN A VERY FAVORABLE ENVIRONMENT WITH LOW (5-10 KNOTS)
VERTICAL WIND SHEAR (VWS), GOOD DIVERGENT OUTFLOW, AND VERY WARM SEA
SURFACE TEMPERATURES. TS 30W IS TRACKING WEST-NORTHWESTWARD ALONG
THE SOUTHERN PERIPHERY OF A DEEP-LAYERED SUBTROPICAL RIDGE (STR).
3. FORECAST REASONING.
A. THERE IS NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE
PREVIOUS PROGNOSTIC REASONING MESSAGE.
B. TS 30W WILL TRACK WEST-NORTHWESTWARD TO WESTWARD ALONG THE
SOUTHERN PERIPHERY OF THE STEERING STR THROUGHOUT THE FORECAST
PERIOD. TS NOCK-TEN WILL CONTINUE TO INTENSIFY UNDER THE VERY
FAVORABLE ENVIRONMENTAL CONDITIONS WITH THE POTENTIAL FOR A PERIOD
OF RAPID INTENSIFICATION (WITHIN THE NEXT 48 HOURS), DUE TO HIGH
OCEAN HEAT CONTENT, PRIOR TO REACHING THE EASTERN COAST OF THE
PHILIPPINES. WITH THE EXCEPTION OF GFDN, DYNAMIC MODEL VORTEX
TRACKERS ARE IN TIGHT AGREEMENT WITH A 55-NM SPREAD IN SOLUTIONS AT
TAU 72. GFDN, WHICH INDICATES SIGNIFICANTLY LOWER INTENSITY VALUES,
IS ERRONEOUSLY DRIVING THE SYSTEM SOUTHWESTWARD WITHIN THE LOW-LEVEL
FLOW AFTER TAU 48. OVERALL, THERE IS HIGH CONFIDENCE DURING THIS
PORTION OF THE FORECAST.
C. AFTER TAU 72, TS 30W IS FORECAST TO TURN SLIGHTLY WEST-
NORTHWESTWARD AS IT APPROACHES THE WESTERN EDGE OF THE STR. HOWEVER,
THE SYSTEM IS NOT EXPECTED TO RE-CURVE DUE TO THE PRESENCE OF
VIGOROUS NORTHEAST MONSOON FLOW OVER THE SOUTH CHINA SEA. TS 30W
WILL WEAKEN AS IT TRACKS ACROSS THE PHILIPPINES BUT SHOULD MAINTAIN
MINIMAL TYPHOON STRENGTH AS IT RE-EMERGES OVER WATER NEAR TAU 96.
ADDITIONAL WEAKENING IS EXPECTED AS THE SYSTEM ENCOUNTERS COOLER,
DRIER AIR AND INCREASING VWS ASSOCIATED WITH THE NORTHEAST SURGE.
DYNAMIC MODEL VORTEX TRACKERS DIVERGE SLIGHTLY IN THE EXTENDED
PERIOD WITH A SPREAD IN SOLUTIONS OF 150-NM AT TAU 120. DUE TO THE
IMPROVED AGREEMENT IN THE DYNAMIC GUIDANCE, THERE IS NOW HIGH
CONFIDENCE IN THE JTWC FORECAST TRACK.//
