SOUTH PACIFIC OCEANS/230600Z-240600ZMAR2017//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION (INVEST 91P) PREVIOUSLY LOCATED
NEAR 12.4S 154.0E, IS NOW LOCATED NEAR 13.5S 154.1E, APPROXIMATELY
290 NM NORTHEAST OF WILLIS ISLAND. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY AND A 222252Z AMSU-B METOP A MICROWAVE IMAGE SHOW PATCHES OF
CONVECTION BEGINNING TO WRAP INTO A SLIGHTLY ELONGATED LOW LEVEL
CIRCULATION CENTER (LLCC). THE DISTURBANCE IS CURRENTLY LOCATED IN
AN AREA OF GOOD POLEWARD OUTFLOW ALOFT, LOW VERTICAL WIND SHEAR (10-
15 KNOTS), AND WARM SEA SURFACE TEMPERATURES (29-30 C). GLOBAL
MODELS ARE IN AGREEMENT THAT THE DISTURBANCE WILL CONTINUE TO TRACK
TO THE SOUTHWEST WITH INTENSIFICATION GRADUALLY OCCURRING OVER THE
NEXT SEVERAL DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
(2) NO OTHER SUSPECT AREAS.//
