     The track coordinates, central pressure and 1-minute average
  maximum sustained wind values were obtained from the operational
  forecast/advisories issued by the Tropical Prediction Center/National
  Hurricane Center in Miami, Florida, for locations east of longitude
  140W, and from the Central Pacific Hurricane Center in Honolulu,
  Hawaii, for locations west of longitude 140W.  A 1-minute averaging
  period is the standard used by all U. S. civilian and military
  warning services for tropical cyclone warnings.

                       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).  Also, Huang Chunliang of Fuzhou City, China, sends me
  each month tracks obtained from warnings issued by the National
  Meteorological Center of China (NMCC), the Central Weather Bureau
  of Taiwan (CWBT) and the Hong Kong Observatory (HKO).    A very
  special thanks to Michael and Chunliang for the assistance they so
  reliably provide.

Note: NMCC did not issue any warnings on this system, as they normally
only do so for systems which reach tropical storm intensity.  However,
the Guangzhou Regional Meteorological Center (GRMC) did issue bulletins
on the tropical depression, and Huang Chunliang sent me their track.
No intensities were indicated, but the coordinates compared remarkably
well with those from JTWC, and the final one, at 29/1800 UTC, was very
close to PAGASA's position.   Since the coordinates from PAGASA's track
at times differed significantly from both JTWC's and JMA's, I am
including them in the table below along with PAGASA's 10-min avg MSW
values.

NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea

                        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.   Occasionally some information may
  have been gleaned from the daily tropical weather outlooks and other
  bulletins issued by the Indian Meteorological Department (IMD), which
  is the World Meteorological Organization's Regional Specialised Meteor-
  ological Centre for the basin.
 
     The reported maximum sustained winds are based on a 1-minute
  averaging period, which is used by all U. S. civilian and military
  weather services for tropical cyclone warnings.     For synoptic
  observations in the North Indian Ocean region, both 10-minute and
  3-minute average winds are employed, but IMD makes no attempt to
  modify the Dvorak scale for estimating tropical cyclone intensity;
  hence, a 1-minute average MSW is implied.

  NOTE: In the case of the third system included below, the LOW was
  classified as a tropical depression only by the Meteorological
  Department of Thailand.   Huang Chunliang sent me their track for
  this depression--a special thanks to Chunliang for sending the
  information.

02 MAY 10 1200  17.5 N   53.3 E         35        Inland in Oman

Note: IMD never classified this system as a cyclonic storm (i.e., a
tropical storm), at least through early on 9 May, the highest Dvorak
classification being T2.0.  However, I do not have available any IMD
bulletins from late on the 9th and early on the 10th as the system
re-intensified and reached its peak intensity as it approached Oman.

Note: JTWC issued a TCFA at 17/2000 UTC, and the coordinates annotated
at 17/2100 UTC above were based on satellite imagery taken at 17/1930
UTC.  The TCFA cancellation at 18/1600 UTC noted that the LLCC had moved
inland at 18/0900 UTC near the location annotated above--in western
Myanmar.    I do not know if the MSW estimates in the track from TMD
supplied by Chunliang represent 1-min avg or 10-min avg values, but
since JTWC estimated the highest 1-min avg MSW in this system at only
20-25 kts, I chose to treat them as 1-min avg winds.  The two central
pressure estimates given above were obtained from JTWC's TCFA and
subsequent STWO.

     The track coordinates as well as the central pressure and 10-minute

  issued by Meteo France's Tropical Cyclone Warning Centre on Reunion
  Island (MFR), which is the World Meteorological Organization's Regional
  Specialised Meteorological Centre for the basin.  The 1-minute average
  maximum sustained wind estimates were taken from warnings issued by the
  Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and Navy,
  located at Pearl Harbor, Hawaii.  The center position coordinates from
  JTWC were compared with those from MFR and annotations made in the
  Remarks column when the differences in general amounted to 40-50 nm
  or more.

Note: Normally for Southern Hemisphere tropical cyclones, I obtain the
coordinates from the official responsible warning agency.  In the case
of Tropical Cyclone Upia, the track presented above was taken from
JTWC's warnings except for the last three positions.  The reasons for
excepting my normal procedure were: (1) Port Moresby had computer
problems which prevented their earlier warnings from being received,
(2) Brisbane apparently placed some of their own analyses of Upia on
BoM's website for certain synoptic hours due to the unavailability of
Port Moresby's warnings, and (3) even with Brisbane helping out, I
still missed some of the warnings, which explains the gaps in the
Central Pressure and 10-min avg MSW columns.  However, the center
position coordinates in general agreed quite well with those from
JTWC with only three annotations needed in the Remarks column.

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

     It has been brought to my attention that I should repeat in the
  cyclone tracks file the caveat which is included in the Author's
  Note at the end of the cyclone summaries.   The tropical cyclone
  tracks which I prepare are based upon the operational warnings/
  advisories/advices/bulletins from 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:

     http://199.10.200.33/jtwc.html>

     In the near future I shall contact the other tropical warning
  centers to see if I can locate any links to sites where their "best
  tracks" might be archived.
