REMAINS LOW

THE AREA OF CONVECTION (REMNANTS OF 01W) PREVIOUSLY
LOCATED NEAR 4.0N 164.5E, IS NOW LOCATED NEAR 5.2N 159.4E,
APPROXIMATELY 125 NM SOUTHEAST OF POHNPEI. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY AND A 110309Z AMSR2 GW1 89GHZ MICROWAVE IMAGE
DEPICT A BROAD, POORLY DEFINED LOW LEVEL CIRCULATION (LLC) COVERED
BY A LARGE AREA OF FLARING CONVECTION WITH A SMALL AREA OF DEEP
CONVECTION TO THE NORTHEAST. THE REMNANTS OF 01W ARE CURRENTLY IN A
FAVORABLE ENVIRONMENT FOR FUTURE DEVELOPMENT WITH WARM (28 TO 30
CELSIUS) SEA SURFACE TEMPERATURES, LOW (10 TO 15 KNOTS) VERTICAL
WIND SHEAR (VWS), AND STRONG POLEWARD AND WESTWARD UPPER LEVEL
OUTFLOW. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT THE SYSTEM WILL
CONTINUE TO TRACK WESTWARD WITH MINIMAL INTENSIFICATION OVER THE
NEXT SEVERAL DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
15 TO 20 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.

I never considered that the models are getting excited about this remnant again because it didn't last long enough to be a trend, in short the current high probability outcome of this remnant is either a TD or dissipation

Favorable environment for future development.

THE AREA OF CONVECTION (INVEST 01W) PREVIOUSLY LOCATED
NEAR 5.2N 159.4E, IS NOW LOCATED NEAR 5.5N 158.2E, APPROXIMATELY 84
NM SOUTH OF POHNPEI. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS AN IMPROVING LOW LEVEL CIRCULATION (LLC) COVERED BY A LARGE
AREA OF FLARING CONVECTION. THE SYSTEM IS CURRENTLY IN A FAVORABLE
ENVIRONMENT FOR FUTURE DEVELOPMENT WITH WARM (28 TO 30 CELSIUS) SEA
SURFACE TEMPERATURES, LOW (10 TO 15 KNOTS) VERTICAL WIND SHEAR(VWS),
AND STRONG POLEWARD AND WESTWARD UPPER LEVEL OUTFLOW. GLOBAL MODELS
ARE IN GOOD AGREEMENT THAT THE SYSTEM WILL CONTINUE TO TRACK
WESTWARD WITH CONSISTENT INTENSIFICATION OVER THE NEXT SEVERAL DAYS.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 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 IS UPGRADED TO MEDIUM.

ScatSat indicated a well-defined but broad LLC 24 hours ago. Looks like it's well on its way to developing. I'd give it a 60-70% chance.
