*TROPICAL STORM (TS) 11W (MUIFA), LOCATED APPROXIMATELY 890 NM
SOUTH-SOUTHEAST OF KADENA AB, HAS TRACKED NORTHWESTWARD AT 05 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
(MSI) SHOWS CURVED CONVECTIVE BANDING PRIMARILY CONCENTRATED ON THE
WESTERN AND SOUTHERN PERIPHERY OF A LOW LEVEL CIRCULATION CENTER
(LLCC). A 28/2021Z 37 GHZ SSMIS SHOWS A MORE DISCERNABLE LLCC, AND A
91 GHZ IMAGE FROM THE SAME TIME SHOWS INCREASING CONVECTIVE
ORGANIZATION IN THE NORTHWEST AND SOUTHWEST QUADRANTS. A 28/0012Z
AMSU-B 89 GHZ IMAGE ALSO INDICATES CURVED BANDING ALONG THE WESTERN
AND SOUTHERN PERIPHERY OF THE LLCC. INITIAL POSITION IS BASED ON THE
ABOVEMENTIONED IMAGERY. THE INITIAL INTENSITY IS BASED ON DVORAK
INTENSITY ESTIMATES FROM PGTW, KNES, AND RJTD RANGING FROM 50 TO 55
KNOTS. UPPER LEVEL ANALYSIS INDICATES THE STORM IS JUST SOUTH OF A
WEAK ANTICYCLONE ALOFT IN A REGION OF MODERATE (25-30 KNOTS)
VERTICAL WIND SHEAR (VWS). RECENT WATER VAPOR IMAGERY SHOWS NEARLY
RADIAL OUTFLOW WITH IMPROVING OUTFLOW IN THE NORTHEASTERN QUADRANT.
DURING THE PAST FEW HOURS TS 11W HAS SLOWED CONSIDERABLY AS THE MID-
LEVEL SUBTROPICAL STEERING RIDGE TO THE NORTH HAS BEGUN RETREATING
WESTWARD IN RESPONSE TO A DEEPENING TROUGH TO THE EAST OF JAPAN. 11W
IS CURRENTLY ROUNDING THE WESTERN EXTENT OF THE NEAR EQUATORIAL
STEERING RIDGE TO THE EAST...(more info)
