SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND
/SOUTH PACIFIC OCEANS/230600Z-240600ZFEB2018//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED
NEAR 5.5N 143.8E, IS NOW LOCATED NEAR 5.9N 134.2E, APPROXIMATELY 90
NM SOUTH-SOUTHWEST OF PALAU. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS FLARING, DISORGANIZED CONVECTION. HOWEVER, THE 230004Z
OSCAT AND 230052 ASCAT IMAGES SHOW STRAIGHT-LINE FLOW AT THE SURFACE
WITH A SMALL POCKET OF 15-20 KNOT WINDS. ENVIRONMENTAL ANALYSIS HAS
WARM (28-30 CELSIUS) SEA SURFACE TEMPERATURES WITH THE UPPER LEVEL
CHARACTERIZED BY LOW (5-15 KNOT) VERTICAL WIND SHEAR AND ADEQUATE
DIVERGENCE ALOFT DUE TO POLEWARD OUTFLOW. GLOBAL DYNAMIC MODELS
MAINTAIN A WEAK CIRCULATION AT LEAST OUT TO THE MIDDLE TAUS, BUT DO
NOT PREDICT DEVELOPMENT TO TROPICAL DEPRESSION STRENGTH AS THE
DISTURBANCE TRACKS WESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED
TO LOW.
(2) NO OTHER SUSPECT AREAS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.//
