JTWC (US NAVY & AIR FORCE) REMARKS:
REMARKS (for Meteorologists): 2 PM (06 GMT) TUE 02 AUGUST POSITION: 22.7N 134.1E.
*TYPHOON (TY) 11W (MUIFA), LOCATED APPROXIMATELY 410 NM EAST-
SOUTHEAST OF KADENA AIR BASE, JAPAN, HAS TRACKED NORTHWARD AT 06
KNOTS OVER THE PAST SIX HOURS. RECENT ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS A WELL DEFINED EYE WITH SLIGHT WEST OF NORTH
MOVEMENT DURING THE PAST FEW HOURS. A 02/0430Z AMSU-B 89 GHZ IMAGE
ALSO SHOWS A WELL DEFINED EYE WITH CONCENTRIC BANDING. RECENT WATER
VAPOR IMAGERY INDICATES TY 11W HAS EXCELLENT EQUATORWARD OUTFLOW AS
WELL AS GOOD POLEWARD OUTFLOW. THE SYSTEM IS ALSO BENEFITTING FROM
OUTFLOW ASSOCIATED WITH A TROPICAL UPPER TROPOSPHERIC TROUGH TO THE
NORTHEAST. 02/00Z UPPER LEVEL STREAMLINE ANALYSIS SHOWS THAT TY 11W
IS CURRENTLY IN A REGION OF WEAK (5-10 KNOTS) VERTICAL WIND SHEAR
(VWS). VWS IS EXPECTED TO REMAIN WEAK AS 11W APPROACHES AN UPPER
LEVEL ANTICYCLONE AND ASSOCIATED RIDGE AXIS TO THE NORTHWEST OF
OKINAWA. TY 11W HAS BEEN UNDER THE STEERING INFLUENCE OF A DEEP
LAYER RIDGE TO THE EAST FOR THE PAST SEVERAL DAYS. HOWEVER, RECENT
SATELLITE IMAGERY INDICATES THE STEERING RIDGE TO THE NORTH HAS
BEGUN TO INFLUENCE TY 11W. DURING THE NEXT 12 HOURS THIS DEEP
LAYERED RIDGE IS EXPECTED TO STEER 11W MORE WESTERLY. THIS RIDGE
WILL CONTINUE TO STEER 11W WESTERLY TO WEST-NORTHWESTERLY THROUGH
TAU 48. AFTER TAU 72, AN APPROACHING TROUGH FROM CHINA WILL WEAKEN
THE WESTERN EXTENT OF THIS RIDGE, AND TY 11W WILL LIKELY TAKE ON A
MORE NORTHERLY MOTION. MODEL GUIDANCE IS IN POOR AGREEMENT IN LATER
TAUS, WITH EGRR AND ECMWF MAINTAINING A STRONG STEERING RIDGE AND
KEEPING TY 11W'S TRACK MORE WESTWARD WHILE GFS AND GFDN FAVOR A MORE
NORTHERLY TRACK IN ANTICIPATION OF A STRONGER MID-LATITUDE TROUGH
APPROACHING FROM THE WEST. THIS FORECAST IS CLOSE TO CONSENSUS AND
IS SIMILAR TO THE PREVIOUS FORECAST...more info)
