SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 29W (KAMMURI)
WARNING NR 006//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM 29W (KAMMURI), LOCATED APPROXIMATELY 194 NM
SOUTHWEST OF ANDERSEN AFB, GUAM HAS TRACKED WESTWARD AT 12 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)
SHOWS AN EXPANSIVE SYSTEM (OVER 600NM ACROSS) WITH EXCEPTIONALLY STRONG
POLEWARD OUTFLOW THAT CONTINUED TO CONSOLIDATE. THE INITIAL POSITION IS
EXTRAPOLATED WITH FAIR CONFIDENCE FROM A MICROWAVE EYE FEATURE IN THE
262052Z SSMIS 37GHZ COLORIZED IMAGE. THE INITIAL INTENSITY OF 55KTS IS
BASED ON THE DVORAK ESTIMATE OF T3.5/55KTS FROM PGTW AND REFLECTS THE
GRADUAL IMPROVEMENT. ANALYSES REVEAL A FAVORABLE ENVIRONMENT WITH LOW
TO MODERATE (05-15KT) VERTICAL WIND SHEAR, ROBUST OUTFLOW ESPECIALLY ON
THE POLEWARD SIDE, AND VERY WARM (>30C) SEA SURFACE TEMPERATURES. THE
CYCLONE IS TRACKING IN THE PHILIPPINE SEA ALONG THE SOUTHERN PERIPHERY
OF THE SUBTROPICAL RIDGE (STR) TO THE NORTH NORTHEAST.
3. FORECAST REASONING.
A. THERE IS NO SIGNIFICANT CHANGE TO THE FORECAST PHILOSOPHY FROM
THE LAST PROGNOSTIC REASONING MESSAGE.
B. TS 29W WILL CONTINUE ON ITS CURRENT TRACK UNDER THE STR UP TO
TAU 12; AFTERWARD, A SHORTWAVE TROUGH APPROACHING FROM THE NORTHWEST
WILL WEAKEN THE STR AND ALLOW THE SYSTEM TO TRACK MORE NORTHWESTWARD
THEN VERY SLOWLY NORTH-NORTHWESTWARD AS IT ENTERS THE COL BETWEEN THE
CURRENT STR AND A SECONDARY, BUILDING STR TO THE NORTHWEST. THE
FAVORABLE ENVIRONMENT WILL FUEL STEADY TO RAPID INTENSIFICATION TO
105KTS BY TAU 72.
C. AFTER TAU 72, TS 29W WILL SLOWLY DRIFT WESTWARD OUT OF THE COL
AFTER THE TROUGH PASSES TO THE NORTHEAST AND THE PRIMARY STR REBUILDS
AND REGAINS STEERING. THE FAVORABLE CONDITIONS WILL PREVAIL AND SUSTAIN
FURTHER INTENSIFICATION TO 115KTS UP TO TAU 120. NUMERICAL MODELS ARE
IN GENERAL AGREEMENT WITH THE OVERALL FORECAST TRACK BUT SPREAD OUT TO
OVER 300NM BY TAU 72 AND OVER 400NM BY TAU 120. THIS, PLUS THE
DIFFERENCES IN ALONG-TRACK SPEED AND THE STORM MOTION UNCERTAINTY IN
THE COL, LEND LOW CONFIDENCE TO THE JTWC TRACK FORECAST.//
