REMARKS:
222100Z POSITION NEAR 10.9S 145.1E.
TROPICAL CYCLONE (TC) 13P (KATE), LOCATED APPROXIMATELY 155 NM
WEST-SOUTHWEST OF PORT MORESBY, PAPUA NEW GUINEA, HAS TRACKED EAST
NORTHEASTWARD AT 02 KNOTS OVER THE PAST SIX HOURS. THE SYSTEM WHICH
HAD BEEN A WEAK DISTURBANCE LOCATED IN THE MONSOON TROUGH HAS
RAPIDLY INTENSIFIED OVER THE LAST 12 HOURS. UPPER LEVEL ANALYSIS
INDICATES GOOD DIVERGENCE ALOFT ASSOCIATED WITH A BROAD AREA OF
DIFFLUENT FLOW OVER THE NORTHWEST CORAL SEA. THE SYSTEM IS EXPECTED
TO SLOWLY TRACK TO THE EAST UNTIL A RIDGE BUILDS OVER THE EASTERN
CORAL SEA AND CAUSES THE SYSTEM TO SHIFT TO A SOUTHERLY TRACK.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 221800Z IS 10 FEET.
NEXT WARNINGS AT 230900Z AND 232100Z.//

REMARKS:

230900Z POSITION NEAR 11.5S 146.7E.
TROPICAL CYCLONE (TC) 13P (KATE), LOCATED APPROXIMATELY 120 NM
SOUTH-SOUTHWEST OF PORT MORESBY, PAPUA NEW GUINEA, HAS TRACKED
SOUTHEASTWARD AT 07 KNOTS OVER THE PAST SIX HOURS. TC 13P IS
BEING STEERED BY NEAR EQUATORIAL RIDGING TO THE NORTH. AFTER
THE DEPARTURE OF A MERIDIONAL TROUGH TO THE EAST OF THE SYSTEM,
RIDGING WILL BUILD INTO THE CORAL SEA AND BEGIN TO STEER THE
STORM ON A MORE SOUTHERLY TRACK. A MODERATE SHEAR ENVIRONMENT
WILL KEEP TC 13P AS A MODERATE STRENGTH STORM OVER THE NEXT
48 HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 230600Z IS 15 FEET.
