Huh. I wonder why this was tagged. The convection looks more tied to divergence aloft east of an upper level low.

00Z PGAC doesn't scream tropical cyclone to me.

Latest visible satellite data shows a developing tropical
disturbance to the east-southeast of Guam. A TUTT cell is seen
just west of the Marianas. Latest PGUA WSR-88D and satellite data
shows numerous showers with isolated thunderstorms over the
region. Buoys show seas remaining between 3 and 5 feet.

A TUTT cell is now just west of the Marianas with a developing
tropical disturbance seen to the east-southeast of Guam. These two
features interacted to bring numerous showers and scattered
thunderstorms to the islands this morning and afternoon. Although
convection has subsided a bit for now, numerous showers and isolated
thunderstorms remain in the forecast as activity is expected to
redevelop over the region this evening. The disturbance will
continue to approach the islands through the night, passing near Guam
over night. A brief period of isolated showers is likely as the
disturbance passes, with scattered showers moving back in during the
day on Monday as the system moves west of the islands. Cloud and
shower coverage are both expected to decrease by monday evening as
the disturbance pulls far enough westward. If the system slows down,
scattered showers could remain a bit longer.
