REMARKS:
241500Z2 POSITION 16.0N7  149.6E0
TYPHOON YATES (28W) CONTINUES MOVING JUST SOUTH OF DUE
WESTWARD AT APPROXIMATELY 12 KNOTS. IT REMAINS A SMALL
SYSTEM. VISIBLE AND ENHANCED INFRARED SATELLITE IMAGERY
INDICATE THE VERY SMALL EYE OF TY YATES HAS BECOME CLOUD
COVERED. AS OF WARNING TIME THE EYE COULD NOT BE
DISCERNED. WARNING INTENSITY HAS DECREASED SLIGHTLY OVER
THE PAST SIX HOURS TO REFLECT FILLING OF THE EYE,
ALTHOUGH THIS SYSTEM HAS MAINTAINED ROUGHLY THE SAME
OVERALL CHARACTERISTICS. WIND RADII AT WARNING TIME ARE
BASED HEAVILY ON THE LATEST MICROWAVE SATELLITE IMAGERY
(SSM/I) ANALYSIS PROVIDED BY AFGWC, BLENDED WITH
AVAILABLE SYNOPTIC DATA. THE FORECAST TRACK FOR TY YATES
IS A CONTINUED WESTWARD TRACK THROUGH 24 HOURS. AS
TROPICAL STORM ZANE (29W) CONTINUES TO INTENSIFY TO THE
WEST OF TY YATES INTERACTION BETWEEN THE TWO SYSTEMS WILL
INCREASE. BEYOND 36 HOURS TY YATES WILL BE IN A REGION OF
SYNOPTIC SCALE POLEWARD WIND FLOW AROUND TS ZANE, AND
THIS IS ANTICIPATED TO TURN TY YATES ONTO A MORE
NORTHWEST TO NORTHWARD TRACK NEAR THE 48 AND 72 HOUR
POSITIONS. NEXT WARNINGS AT 242100Z9 (DTG 241951Z2),
250300Z0 (DTG 250151Z4), 250900Z6 (DTG 250751Z0) AND
