REMARKS (for Meteorologists): 2 PM (06 GMT) FRI 29 JULY POSITION: 13.5N 133.9E.
*TROPICAL STORM (TS) 11W (MUIFA), LOCATED APPROXIMATELY 830 NM SOUTH-
SOUTHEAST OF OKINAWA, JAPAN, HAS TRACKED NORTHWARD AT 06 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS
THE LOW LEVEL CIRCULATION CENTER REMAINS TOTALLY OBSCURED BY A COLD
DENSE OVERCAST THAT HAS MAINTAINED DEPTH. THE INITIAL POSTION IS
BASED ON A 290422Z AMSR-E MICROWAVE IMAGE SHOWING A WARM SEMI-CIRCLE
SIGNATURE. THE INITIAL INTENSITY IS SUPPORTED BY DVORAK ESTIMATES
FROM PGTW AND KNES. UPPER LEVEL ANALYSIS INDICATES THE STORM IS JUST
SOUTH OF A WEAK ANTICYCLONE ALOFT IN A REGION OF MODERATE (25-30
KNOTS) NORTHEASTERLY VERTICAL WIND SHEAR (VWS). RECENT WATER VAPOR
IMAGERY SHOWS SHARP OUTLINES IN THE NORTHEASTERN QUADRANT INDICATING
SUBSIDENCE. TS 11W IS CURRENTLY TRACKING ALONG THE WESTERN EXTENT OF
THE NEAR EQUATORIAL RIDGE (NER) TO THE EAST. TS 11W WILL CONTINUE TO
TRACK ALONG THE WESTERN PERIPHERY OF THE NER AND AS IT GAINS
LATITUDE, VWS WILL RELAX, SEA SURFACE TEMPERATURES WILL REMAIN HIGH,
AND UPPER LEVEL OUTFLOW WILL REMAIN FAVORABLE, RESULTING IN STEADY
INTENSIFICATION. AFTER TAU 72, A BUILDING STR EAST OF HONSHU, JAPAN
WILL NUDGE TS 11W LEFT OF TRACK. THE AVAILABLE NUMERICAL GUIDANCE
FANS OUT TO APPROXIMATELY 20 DEGREE SPREAD, ALL FAVORING THE
S-SHAPED TRACK DESCRIBED ABOVE WITH THE EXCEPTION OF WBAR THAT
CONTINUES TO BE TO THE LEFT OF THE MODEL ENVELOPE AND MAINTAINS A
POLEWARD TRAJECTORY. THIS TRACK FORECAST IS SLIGHTLY TO THE RIGHT OF
CONSENSUS TO OFFSET WBAR'S UNREALISTIC PULL...(more info)
