REMARKS:
292100Z POSITION NEAR 12.9N 146.8E. TROPICAL STORM (TS) 18W
(EIGHTEEN) LOCATED APPROXIMATELY 165 NM EAST-SOUTHEAST OF GUAM, HAS
TRACKED WEST-NORTHWESTWARD AT 15 KNOTS OVER THE PAST SIX HOURS.
RECENT ANIMATED INFRARED IMAGERY SHOWS A POORLY ORGANIZED MASS OF
CONVECTION WITH VERY LITTLE STRUCTURE. A 291514Z TRMM PASS SHOWS A
SLIGHTLY CURVED LINE OF DEEP CONVECTION SHEARED TO THE WEST OF AN
ELONGATED LOW LEVEL CIRCULATION CENTER. TS 18W IS CURRENTLY TRACKING
ALONG THE SOUTHERN PERIPHERY OF THE LOW- TO MID-LEVEL SUBTROPICAL
RIDGE LOCATED TO THE NORTH, AND IS LOCATED BETWEEN THE TWO TROPICAL
CYCLONES TS 19W AND TS 20W. THE SYSTEM'S PLACEMENT NEAR TWO STORMS
HAS DISRUPTED ITS INFLOW AND OUTFLOW PATTERNS AND HAS CAUSED THE
SYSTEM TO STRUGGLE TO DEVELOP. AS IT CLOSES THE DISTANCE TO TS 19W,
LOCATED TO THE WEST-SOUTHWEST, THE INFLOW AND OUTFLOW WILL BECOME
FURTHER DISRUPTED AND THE SYSTEM WILL START TO DISSIPATE BEFORE
EVENTUALLY BECOMING CAPTURED IN THE OUTER PERIPHERY OF TS 19W. THIS
IS REFLECTED IN THE TRACK AS 18W IS EXPECTED TO TURN MORE WESTWARD
AS IT FEELS THE EFFECT OF WEAK BINARY INTERACTION BEFORE BEING
CAPTURED BY 19W, TURNING MORE NORTHWESTWARD, AND DISSIPATING ONCE IT
IS IN THE WIND FIELD FOR 19W. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
291800Z IS 16 FEET. NEXT WARNINGS AT 300300Z, 300900Z, 301500Z AND
302100Z. REFER TO TROPICAL STORM 17W (KETSANA) WARNINGS (WTPN31

Hmm, woke up this morning on Guam to find that 18W has pretty much died . Now we're concerned about 20W.
