REMARKS:
280900Z9 POSITION 23.8N3  125.2E0
TYPHOON ZANE (29W) IS MOVING NORTHWARD AT 06 KNOTS. IT
HAS MAINTAINED INTENSITY OVER THE PAST SIX HOURS AND IS
LIKELY TO UNDERGO ANOTHER DIURNAL CONVECTIVE PEAK
TONIGHT. TY ZANE IS STILL MOVING JUST WEST OF NORTH AT
THIS POINT IN TIME, AS INDICATED BY BOTH RADAR AND
VISIBLE SATELLITE FIXES. A WEAK ANTICYCLONE TO THE
SOUTHEAST OF TY ZANE IS SHIFTING NORTH WITH TY ZANE, BUT
NOT QUITE AS FAST. TY ZANE IS ANTICIPATED TO TOP OVER THE
INDUCED RIDGE NEAR 24 HOURS AND BEGIN A SLOW ACCELERATION
TO THE NORTHEAST. AFTER TY ZANE MOVES NORTH OF THE
SUBTROPICAL RIDGE THE STRONG UPPER-LEVEL WESTERLIES ARE
EXPECTED TO BEGIN WEAKENING THE SYSTEM DUE TO STRONG
VERTICAL WIND SHEAR EFFECTS. NEXT WARNINGS AT 281500Z6
(DTG 281353Z2), 282100Z3 (DTG 281953Z8), 290300Z4 (DTG
290153Z0) AND 290900Z0 (DTG 290753Z6). MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 280600Z6 IS 2
