REMARKS (for Meteorologists): 2 AM (18 GMT) WED 03 AUGUST POSITION: 23.8N 133.2E.
*TYPHOON (TY) 11W (MUIFA), LOCATED APPROXIMATELY 320 NM EAST-
SOUTHEAST OF KADENA AIR BASE, JAPAN, HAS TRACKED NORTHWESTWARD
AT 07 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE
IMAGERY SHOWS A CLEAR 21 NM IRREGULAR EYE. A 02/1703Z 89 GHZ AMSU
IMAGE SHOWS A SECONDARY CONCENTRIC CONVECTIVE BAND BEGINNING TO FORM
AROUND THE MAIN EYEWALL. HOWEVER, ANIMATED TOTAL PRECIPITABLE WATER
IMAGERY SHOWS RELATIVELY DRIER AIR TO THE WEST OF TY 11W WHICH MAY
HINDER THE SECOND CONVECTIVE RING FROM COMPLETELY ENCOMPASSING THE
EYEWALL AND THEREFORE POSSIBLY INHIBIT ANOTHER EYE WALL REPLACEMENT
CYCLE. TY 11W WILL CONTINUE TO BE STEERED NORTHWESTWARD BY A DEEP
LAYERED BUILDING SUBTROPICAL RIDGE CENTERED APPROXIMATELY SOUTHEAST
OF HONSHU, JAPAN. THERE IS HIGH CONFIDENCE IN THE INITIAL POSITION
DUE TO THE EYE FEATURE AND THE INITIAL INTENSITY REMAINS STEADY AT
110 KNOTS AS ALL REPORTING AGENCY DVORAK INTENSITY ESTIMATES HAVE
DONE THE SAME...more info)
>> MUIFA, meaning: Plum blossom. Name contributed by: Macao, China.
