JTWC (US NAVY & AIR FORCE) REMARKS:

REMARKS (for Meteorologists): 2 PM (06 GMT) FRI 27 AUGUST POSITION: 14.9N 117.6E.
*RECENT ANIMATED MULTI-SPECTRAL SATELLITE IMAGERY
REVEALS THAT OVER THE PAST SIX HOURS TD 07W HAS RAPIDLY DEVELOPED. A
262218Z WINDSAT PASS AND A PARTIAL 270122Z ASCAT PASS INDICATE A
WELL DEFINED LLCC WITH 25 KNOT WINDS AT THE SYSTEM CENTER.
OBSERVATIONS WITHIN 75 NM SOUTHEAST OF THE SYSTEM SHOW WINDS OUT OF
THE SOUTHWEST AT 25 KNOTS AND PRESSURE AT 1005 MB. A 270234Z 37 GHZ
TRMM MICROWAVE IMAGE SHOWS TIGHTLY CURVED CONVECTIVE BANDING
WRAPPING IN FROM THE SOUTHERN PERIPHERY OF THE SYSTEM WITH WEAKER
BANDING ALONG THE NORTHERN PERIPHERY. THE CURRENT INTENSITY IS BASED
ON THE AFOREMENTIONED ASCAT PASS AS WELL AS DVORAK ESTIMATES OF 25
KNOTS FROM PGTW AND KNES. ENVIRONMENTAL ANALYSIS REVEALS THAT THE
SYSTEM IS IN A FAVORABLE ENVIRONMENT WITH LOW VERTICAL WIND SHEAR
(<15 KNOTS), ENHANCED UPPER LEVEL DIFFLUENCE, AND HIGH SEA SURFACE
TEMPERATURES. TD 07W IS CURRENTLY TRACKING WESTWARD UNDER THE
INFLUENCE OF THE LOW TO MID SUBTROPICAL STEERING RIDGE ANCHORED TO
THE SOUTH OF JAPAN. NEAR TAU 24, TD 06W IS FORECAST TO BEGIN TURNING
POLEWARD AS A DEEPENING MID-LATITUDE TROUGH TRACKS OVER EASTERN
CHINA. DUE TO THE RAPID DEVELOPMENT OF THIS SYSTEM, NUMERICAL MODEL
GUIDANCE HAS BEEN SLOW TO INITIALIZE THE SYSTEM, RESULTING IN POOR
MODEL AGREEMENT. THIS FORECAST IS IN CLOSE AGREEMENT TO MODEL
CONSENSUS.
