WATER VAPOR WIND DATA INDICATED THAT THE TROUGH AXIS WAS ALONG A LINE FROM 30N 171W TO 22N 166W THEN SOUTHWESTWARD THROUGH 10N 172W. THE TROUGH HAS PRODUCED A LARGE AREA OF BROKEN TO OVERCAST LAYERED CLOUDS AND EMBEDDED THUNDERSTORMS EXTENDING 700 TO 800 MILES NORTHWEST OF A LINE FROM 30N 150W TO 18N 161W. THIS AREA COVERED ALL OF KAUAI AND MOST OF OAHU. EMBEDDED THUNDERSTORM TOPS REACHED UP TO 49000 FT ABOUT 60 MILES EAST OF LIHUE AND 48000 FT ABOUT 500 MILES WEST OF BARKING SANDS. RADAR DATA FROM KAUAI INDICATED A LINE OF VERY HEAVY RAINFALL IN THE KAUAI CHANNEL. INDIVIDUAL RAIN CELLS WITHIN THE LINE WERE MOVING TOWARD THE NORTH-NORTHEAST AT 20 TO 25 MILES PER HOUR WHILE THE LINE ITSELF WAS PROGRESSING EASTWARD AT 15 MILES PER HOUR.
