   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION IS LOCATED NEAR 12S3
179E7.  SATELLITE IMAGERY AND SYNOPTIC DATA INDICATE THAT
THE CONVECTION HAS SUSTAINED ITSELF FOR SEVERAL DAYS AND
HAS AN ASSOCIATED SURFACE CIRCULATION. THIS DISTURBANCE
HAS CROSSED OVER THE DATELINE INTO JTWC=S AOR. THE
POTENTIAL FOR SIGNIFICANT TROPICAL CYCLONE DEVELOPMENT
WITHIN THE NEXT 24 HOURS IS GOOD. THIS AREA IS THE
SUBJECT OF A TROPICAL CYCLONE FORMATION ALERT ISSUED BY
NPMOC, PEARL HARBOR, HI. SEE REF B (TROPICAL CYCLONE
FORMATION ALERT (WPS21 PHNC 272100)) FOR FURTHER DETAILS.
