*TYPHOON (TY) 15W (MEGI), LOCATED APPROXIMATELY 455 NM SOUTHEAST
OF HONG KONG, CHINA, HAS TRACKED WESTWARD AT 07 KNOTS OVER THE PAST
SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY INDICATES THAT
TY 15W HAS CONTINUED TO RE-CONSOLIDATE AND HAS DEVELOPED A 10-NM
DIAMETER IRREGULAR EYE OVER THE PAST 06 HOURS. A 182321Z TRMM 37H
IMAGE SHOWS A WELL-DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH
A MICROWAVE EYE FEATURE AND STRONG CORE CONVECTION OVER ALL
QUADRANTS. ANIMATED WATER VAPOR IMAGERY DEPICTS EXCELLENT RADIAL OUTFLOW
ESPECIALLY POLEWARD OUTFLOW, ENHANCED BY STRONG WESTERLY FLOW ACROSS
CENTRAL CHINA. THERE IS GOOD CONFIDENCE IN THE CURRENT POSITION
BASED ON THE TRMM IMAGE AND EYE. THE CURRENT INTENSITY OF 90 KNOTS
IS BASED ON DVORAK ESTIMATES OF 90 KNOTS FROM PGTW AND KNES...(more)
