AS BROAD UPPER LEVEL TROFING OVR THE CENTRAL PAC OCEAN SLIDES
SLOWLY TO THE EAST. THE TROF WILL BEGIN TO AMPLIFY SOMEWHAT AS IT
MOVES CLOSER TO THE OFF WTRS TUE INTO WED.

OFF WATERS INTO NEXT WEEK AS THE MAIN STORM TRACK AND ASSOC 
HIGHER BL WINDS REMAIN W OF THE WATERS...WITH MAX BL WINDS 
SPEEDS REMAINING BELOW 25 KT ACROSS THE REGION INTO NEXT WEEK.

GLOBAL MODELS FOR TUE AND WED...AS THE GNRL WX PATTERN ACROSS THE
