*THE STORM HAS MADE MODEST INTENSITY GAINS
AND HAS TRACKED NORTHWEST TO WEST-NORTHWEST OVER THE PAST TWELVE
HOURS ALONG THE SOUTHWESTERN PERIPHERY OF A LOW TO MID-LEVEL
STEERING RIDGE. CURRENT DVORAK ESTIMATES FROM PGTW AND RJTD
APPROXIMATE A 35 TO 45 KNOT SYSTEM. THERE IS INCREASED UNCERTAINTY
IN THE 20/1200Z INITIAL FORECAST POSITION WHEN COMPARED TO SIX HOURS
AGO. MICROWAVE IMAGERY HAS BEEN MORE OR LESS LIMITED AND NON-
CONCLUSIVE AND VISIBLE SATELLITE IMAGERY HAS BECOME UNAVAILABLE WITH
SUNSET. HOWEVER, THERE IS FAIR CONFIDENCE IN THE 20/0600Z POSITION
IN LIGHT OF A 200626Z AMSU-B MICROWAVE IMAGE. NONETHELESS, THE
CURRENT POSITION IS TUCKED BENEATH THE EASTERN PORTION OF A SMALL
AREA OF FLARING CENTRAL CONVECTION THAT ALSO COINCIDES WITH THE
LATEST POSITION FIX FROM RJTD. OVERALL THE CONVECTIVE SIGNATURE
REMAINS FAIRLY UNIMPRESSIVE AND FRAGMENTED. IN ADDITION, CONVECTION
HAS BEEN SOMEWHAT DAMPENED ON THE WESTERN PERIPHERY OF THE
CIRCULATION DUE TO AN UPPER LEVEL TROUGH POSITIONED OVER THE EXTREME-
WESTERN SOUTH CHINA SEA...(more)
