SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 01W (MEKKHALA) WARNING
NR 09//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 01W (MEKKHALA), LOCATED APPROXIMATELY 277 NM
NORTH-NORTHWEST OF KOROR, PALAU, HAS TRACKED WESTWARD AT 08 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY (EIR) REVEALS A PARTIALLY EXPOSED LOW LEVEL CIRCULATION
CENTER (LLCC) WITH THE BULK OF THE DEEP CONVECTION CONFINED TO THE
WESTERN SEMI-CIRCLE. A 150925Z SSMIS 37GHZ MICROWAVE PASS REVEALED A
LOOSELY WRAPPING LLCC AS THE OVERALL CONVECTIVE STRUCTURE REMAINS
UNCHANGED. THE CURRENT POSITION IS BASED ON THE EIR ANIMATION AND
PERSISTENCE FROM THE MICROWAVE PASS WITH FAIR CONFIDENCE. THE
CURRENT INTENSITY REMAINS AT 35 KTS BASED ON THE UNCHANGED STRUCTURE
AND DVORAK INTENSITY ESTIMATES OF THE SAME VALUE FROM PGTW AND KNES.
UPPER LEVEL ANALYSIS CONTINUES TO SHOW THAT TS 01W REMAINS IN A
MARGINALLY FAVORABLE ENVIRONMENT WITH MODERATE (15-20 KNOTS)
VERTICAL WIND SHEAR (VWS) WHICH IS BEING OFFSET BY GOOD POLEWARD
OUTFLOW. TS MEKKHALA IS TRACKING WEST-NORTHWESTWARD ALONG THE
SOUTHERN PERIPHERY OF A LOW- TO MID-LEVEL REFLECTION OF THE
SUBTROPICAL RIDGE (STR).
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. THROUGH TAU 36, TS 01W WILL CONTINUE TO TRACK GENERALLY WEST
UNDER THE SOUTHERN PERIPHERY OF THE STR. AFTER TAU 36, A BREAK IN
THE STR WILL ALLOW THE SYSTEM TO TURN SLIGHTLY MORE WEST-NORTHWEST
AS IT MAKES LANDFALL ACROSS THE CENTRAL PHILLIPINE ISLANDS. TS
MEKKHALA IS FORECAST TO SLOWLY INTENSIFY THROUGH TAU 36 REACHING A
PEAK INTENSITY OF 50 KNOTS PRIOR TO MAKING LANDFALL. AFTER TAU 36,
THE SYSTEM WILL WEAKEN DUE TO THE FRICTIONAL EFFECTS OF LAND,
INCREASED VWS, AND ENCOUNTERING MORE STABLE AIR ASSOCIATED WITH THE
PERSISTENT NORTHEASTERN SURGE. THERE IS A FAIR AMOUNT OF UNCERTAINTY
IN THE TRACK AFTER LANDFALL AS THE NUMERIC MODEL GUIDANCE REMAINS
SPREAD DUE TO DISAGREEMENT IN THE INTENSITY OF THE SYSTEM AND THE
ORIENTATION OF THE STR. THERE IS A POSSIBILITY THAT THIS SYSTEM MAY
DISSIPATE OVER THE ISLANDS BY TAU 72.
C. AFTER TAU 72, TS MEKKHALA IS EXPECTED TO TRACK WEST INTO THE
SOUTH CHINA SEA AS A WEAKENED TROPICAL DEPRESSION. THE NUMERIC MODEL
GUIDANCE REMAINS WIDELY SPREAD AND ERRATIC AS PREVIOUSLY MENTIONED.
GFS HAS SWITCHED BACK TO THE NORTH, ALONG WITH EGRR AND THE JAPANESE
ENSEMBLE IN A HIGHLY UNLIKELY NORTHWARD TURN INTO THE SURGE. COAMPS-
TC AND GFDN REMAIN ON A WEST-SOUTHWEST TRACK AS THEY REVEAL A WEAKER
THAN FORECAST SYSTEM. THE JTWC TRACK LIES IN CLOSE AGREEMENT WITH
THE ECMWF AND GFS ENSEMBLE SOLUTION AS THEY BEST REPRESENT THE
INTENSITY FORECAST. DUE TO THIS LARGE VARIATION IN MODEL SOLUTIONS,
THE CONFIDENCE IN THE JTWC FORECAST TRACK REMAINS LOW.//

1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 01W (MEKKHALA), LOCATED APPROXIMATELY 662 NM
EAST-SOUTHEAST OF MANILA, PHILIPPINES, HAS TRACKED WESTWARD AT 08
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY (EIR) CONTINUES TO DEPICT LOW-LEVEL SPIRAL BANDING WRAPPING
INTO A PARTIALLY EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH
ASYMMETRIC DEEP CONVECTION DISPLACED TO THE WEST OF THE LLCC. A
151821Z SSMI 85GHZ IMAGE REVEALS WEAKENED CONVECTIVE BANDING
WRAPPING INTO THE WESTERN QUADRANT OF THE LLCC. UPPER LEVEL ANALYSIS
INDICATES CONTINUED SOUTHEASTERLY VERTICAL WIND SHEAR (15-20 KNOTS)
WITH WEAKENED POLEWARD OUTFLOW AS EVIDENT IN WATER VAPOR IMAGERY.
THE CURRENT POSITION IS BASED ON THE EIR ANIMATION AND SSMI
MICROWAVE IMAGE WITH GOOD CONFIDENCE. THE INITIAL INTENSITY REMAINS
AT 35 KNOTS BASED ON T2.5 FROM ALL AGENCIES. TS MEKKHALA IS
CURRENTLY TRACKING WESTWARD ALONG THE SOUTHERN PERIPHERY OF A LOW-
TO MID-LEVEL SUB-TROPICAL RIDGE (STR).
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TS 01W WILL CONTINUE TO TRACK WEST TO WEST-NORTHWESTWARD UNDER
AN EXTENSION OF THE STR LOCATED TO THE NORTHEAST UNTIL MAKING
LANDFALL IN CENTRAL PHILIPPINES NEAR TAU 36. TS 01W IS FORECAST TO
SLOWLY INTENSIFY PRIOR TO MAKING LANDFALL DUE TO FAVORABLE SSTS,
HOWEVER, UNFAVORABLE UPPER LEVEL CONDITIONS WILL INHIBIT FURTHER
INTENSIFICATION. MODEL GUIDANCE HAS COME INTO BETTER AGREEMENT
THROUGH THIS PORTION OF THE FORECAST BUT CONTINUES TO SHOW A
BIFURCATION NEAR TAU 48, WITH GFDN AND COAMPS-TC TAKING A WEAKER
SYSTEM ACROSS THE SOUTHERN PHILIPPINES.
C. AFTER TAU 72, TS MEKKHALA WILL RAPIDLY WEAKEN DUE TO LAND
INTERACTION AND INCREASED VWS. THIS WILL CAUSE THE SYSTEM TO TURN TO
THE WEST-SOUTHWEST UNDER THE INFLUENCE OF THE NORTHEASTERLY SURGE.
IN THE EXTANDED TAUS, GFS AND JENS RECURVE THE SYSTEM TO THE
NORTHEAST. HOWEVER, AFTER CONDUCTING A MODEL ANALYSIS, THEY ARE
ERRONEOUSLY JUMPING VORTICITY MAXIMUMS TO AN AREA WITHIN THE MID-
LATITUDE WESTERLIES. THE OFFICIAL JTWC FORECAST LIES CLOSE TO THE
MULTI-MODEL CONSENSUS, HOWEVER, DUE TO THE BIFURCATION MENTIONED
ABOVE, THERE IS LOW CONFIDENCE IN THE FORECAST TRACK.//

It's very pretty

[ejeraldmc]

Am I the only one thinking this could be stronger than expected?

[euro6208]

This doesn't look like a minimal tropical storm at all...I'm thinking at least 50-55 knots and ADT is now 3.5...

LLC right under that healthy CDO...

[ejeraldmc]

The CDO seems to be getting larger.

B. TS 01W WILL CONTINUE TO TRACK WESTWARD TO WEST-NORTHWESTWARD
UNDER THE INFLUENCE OF THE STR THROUGH TAU 72 AND WILL MAKE LANDFALL
IN THE CENTRAL PHILIPPINES JUST AFTER TAU 24. TS MEKKHALA IS
FORECAST TO SLOWLY INTENSIFY PRIOR TO MAKING LANDFALL DUE TO STRONG

LANDFALL, THE SYSTEM IS EXPECTED TO WEAKEN AS LAND INTERACTION,
INCREASED VWS, AND INTERACTION WITH THE NORTHEAST SURGE EVENTUALLY
LEAD TO DISSIPATION WITH THE REMNANTS EMERGING IN THE SOUTH CHINA
SEA. NUMERIC MODEL GUIDANCE REMAINS WIDELY SPREAD AFTER LANDFALL AS
MOST OF THE TRACKERS LOSE THE VORTEX OF THE SYSTEM AND CONTINUE TO
