NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180


                          Sources of Information
                          ----------------------

     The track coordinates and 1-minute average maximum sustained wind
  values in general were taken from operational warnings issued by the
  Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and Navy,
  located at Pearl Harbor, Hawaii.  The central pressure and 10-minute
  average maximum sustained wind estimates for most systems were obtained
  from warnings issued by the Japanese Meteorological Agency (JMA), which
  is the World Meteorological Organization's Regional Specialised Meteor-
  ological Centre for the basin.  In a few instances, information from
  warnings issued by other Asian warning centers may have been utilized.
  The center position coordinates from JMA and other centers were com-
  pared with those from JTWC and annotations made in the Remarks column
  when the differences in general amounted to 40-50 nm or more.

     Michael V. Padua of Naga City in the Philippines, owner of the
  Typhoon 2000 website, sends me cyclone tracks based upon warnings
  issued by the Japanese Meteorological Agency and the Philippines'
  Atmospheric, Geophysical & Astronomical Services Administration
  (PAGASA).  A special thanks to Michael for his efforts.

  NOTE: No tropical or subtropical cyclone warnings were issued for the
  first system below.  The track was pieced together from SAB satellite
  bulletins and High Seas Bulletins issued by JMA.

Tomas was 35 kts from 18/0600 through 18/1800 UTC, the system being
downgraded to a tropical depression at 19/0000 UTC.  As is evident from
the above table, JTWC never upgraded this system to tropical storm
status.

Note: This tropical cyclone formed within the same general area of 
disturbed weather associated with Tropical Disturbance 04.  The first 
MFR warning on Tropical Disturbance 05 stated (slightly edited):

"THE LOW-LEVEL CIRCULATION CENTER MONITORED AND NUMBERED 4 HAS DISSIPATED
BUT THE CONVECTIVE ACTIVITY ASSOCIATED WITH EX-TROPICAL DISTURBANCE NR 4 
HAS PERSISTED.   DURING THE NIGHT, SEVERAL RELATIVE AND SHORT-LIVED 
CENTERS HAVE PROBABLY EXISTED AT THE MERCY OF CONVECTIVE PULSATIONS, 
MAINLY EAST OF 55E.  LAST SATELLITE IMAGERY SHOWS NOW A NEW CLOCKWISE 
CIRCULATION ORGANIZING AROUND A NEW CENTER WHICH APPEARS TO BE THE MAIN
ONE.  THE DISSIPATION OF THE FIRST MONITORED SYSTEM AND THE GENESIS OF 
THIS NEW ONE JUSTIFIES THE RE-NUMBERING."

              !!!!!!  IMPORTANT NOTE - PLEASE READ  !!!!!!

     To repeat the caveat which is included in the Author's Note
  at the end of the cyclone summaries--the tropical cyclone tracks
  I prepare are based upon the operational warnings/advisories/
  advices/bulletins which are issued by the various tropical cyclone
  warning agencies around the world.   Users of these tracks should
  be aware that they are preliminary and subject to revision during
  post-seasonal analyses of the cyclones by the forecasters and
  analysts at the several warning centers.

     For the Atlantic and Northeast Pacific basins, official tropical
  cyclone reports and "best tracks" can be found at the website of
  the Tropical Prediction Center/National Hurricane Center:

     http://www.nhc.noaa.gov>

     The Joint Typhoon Warning Center's website contains links to their
  Annual Tropical Cyclone Reports which include that agency's "best
  tracks" for tropical cyclones in the Northwest Pacific basin, the
  North Indian Ocean, and the Southern Hemisphere:
