THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED
NEAR 23.1N 175.0E IS NOW LOCATED NEAR 24.7N 176.5E, APPROXIMATELY
390 NM WEST-SOUTHWEST OF MIDWAY ATOLL. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A COMPACT, DEFINED LOW-LEVEL CIRCULATION
CENTER (LLCC) WITH PERSISTENT DEEP CONVECTION OVER THE EASTERN SEMI-
CIRCLE. A 030217Z SSMI 85GHZ IMAGE SHOWS SHALLOW BANDING WRAPPING
INTO A DEFINED CENTER WITH WEAK CURVED DEEP CONVECTION OVER THE EAST
QUADRANT OF THE LLCC. UPPER-LEVEL ANALYSIS INDICATES AN UNFAVORABLE
ENVIRONMENT WITH STRONG VERTICAL WIND SHEAR AND DIFFLUENT FLOW
ASSOCIATED WITH TS 13W'S OUTFLOW. GLOBAL MODELS INDICATE SIGNIFICANT
DEVELOPMENT AFTER TWO TO THREE DAYS AS TS 13W TRACKS NORTHWARD AND
UPPER-LEVEL CONDITIONS IMPROVE. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 12 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 27.3N
175.5E, IS NOW LOCATED NEAR 28.3N 174.2E, APPROXIMATELY 440 NM WEST
OF MIDWAY. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS AN
EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH NO ASSOCIATED
CONVECTION. A 032222Z METOP-B ASCAT PASS SHOWS AN INCREASE OF WIND
SPEEDS AROUND THE EASTERN PERIPHERY OF THE LLCC WITH THE PRESENCE OF
25 KNOTS. UPPER-LEVEL ANALYSIS INDICATES AN UNFAVORABLE ENVIRONMENT
WITH STRONG VERTICAL WIND SHEAR ASSOCIATED WITH THE UPPER-LEVEL JET.
THIS SYSTEM IS BEING ASSESSED AS SUBTROPICAL IN NATURE DUE TO THE
ABSENCE OF A WARM CORE. GLOBAL MODELS CONTINUE TO STRUGGLE WITH
POSITION AND MOVEMENT OF THIS SYSTEM OVER THE NEXT 48 HOURS, BUT THE
GENERAL MOVEMENT OVER THE LAST SIX HOURS WAS TO THE NORTHWEST AT 16
KNOTS AND DOES NOT INDICATE IT WILL TRANSITION INTO A TROPICAL
SYSTEM. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS REMAINS LOW.

THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED
NEAR 28.3N 174.2E, HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
