Northwest of Guam.

AN AREA OF CONVECTION HAS PERSISTED NEAR 19.9N 141.5E,
APPROXIMATELY 440 NM NORTH-NORTHWEST OF GUAM. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS A FULLY EXPOSED LLCC TRACKING QUICKLY TO THE
NORTH-NORTHWEST. THERE HAS BEEN DEEP CONVECTION LOCATED TO THE WEST
OF THE LLCC OVER THE PAST 12 TO 24 HOURS. UPPER LEVEL ANALYSIS
INDICATES THE LLCC IS LOCATED UNDER A SUBTROPICAL RIDGE AXIS WHICH
IS CREATING MODERATE VWS (15 TO 20 KNOTS). THE VWS IS CAUSING THE
SEPARATION OF THE LLCC AND DEEP CONVECTION. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. BASED ON THE STRUCTURE OF
THE LLCC BUT A LACK OF DEEP CONVECTION, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
