     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 located in Miami, Florida.   A 1-minute averaging
  period is the standard used by all U. S. civilian and military
  warning services for tropical cyclone warnings.

     A special thanks to David Roth of the Hydrometeorological Prediction
  Center (HPC) for compiling and sending me the track for the early,
  non-tropical stage of Tropical Storm Peter.  The official TPC/NHC
  Best Tracks for Odette and Peter can be found along with the storm
  reports on NHC's website:

Note: The portion of the track above prior to 09/1200 UTC was provided by
David Roth, a meteorologist at the Hydrometeorological Prediction Center
in Maryland.  The CP and MSW values for that portion of the track were
gleaned from ship reports.   The TPC/NHC Best Track for Peter indicates
that the system had achieved subtropical storm status at 07/1800 UTC
and had become a tropical storm at 09/0600 UTC.  The first operational
advisory naming Peter was issued at 09/1500 UTC.  Along with Tropical
Storm Odette a few days earlier, the development of Peter makes December
of 2003 the first time since 1887 that two tropical storms have formed
in the month of December.  Also, these two cyclones along with Tropical
Storm Ana in April makes 2003 the first year since 1887 that three
tropical storms have formed outside the nominal June to November season.

                        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: The 10-min MSW estimates after 25/1800 UTC were taken from PAGASA's
bulletins.  JMA downgraded the system to weak depression status (25 kts
or less) at 26/0000 UTC.  NMCC did not issue warnings on TC-27W as they
normally issue warnings only for tropical storms/typhoons and did not
adjudge this system to be of tropical storm intensity.  HKO classified
the system as a tropical depression but did not issue normal warnings
as the depression remained outside that agency's AOR.  Neither were
any local numbered warnings issued by CWBT (Taiwan), but the agency
did upgrade the disturbance to depression status at 24/0000 UTC, and
then downgraded it back to a LPA at 27/1200 UTC.  No specific wind
estimations were given, but CWBT did not forecast the system to reach
tropical storm intensity.

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.

     Thanks to Huang Chunliang for compiling, typing and sending me
  the tracks for TC-03B based on bulletins from the meteorological
  departments of India (IMD) and Thailand (TMD).

Note: Huang Chunliang compiled tracks based on operational warnings
from both the India Meteorological Department (IMD) and the Thai
Meteorological Department (TMD).  Initially, I attempted to supplement
the JTWC-based track with positions and intensities gleaned from the
IMD and TMD tracks in a manner similar to the way I treat the multiple
tracks I normally have available for Western Pacific cyclones, but
because those tracks contained data points at irregular hours and not
at the standard synoptic hours, and also because JTWC's track was at
only 12-hourly intervals, it quickly became very messy and subjective
(on my part).  So I've simply included the tracks based on IMD's and
TMD's operational warnings below (with minor editing).

     The track coordinates as well as the central pressure and 10-minute
  average maximum sustained wind estimates were obtained from warnings
  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.

                        ----------------------

     The track coordinates as well as the central pressure and 10-minute
  average maximum sustained wind estimates were obtained from warnings
  issued by the Tropical Cyclone Warning Centres at Darwin, Northern
  Territory; Brisbane, Queensland; and Port Moresby, Papua New Guinea.
  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 the
  Australian centres and annotations made in the Remarks column when the
  differences in general amounted to 40-50 nm or more.

             !!!!!!  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:

     http://199.10.200.33/jtwc.html>


  SPECIAL NOTE:  Back issues of the global tropical cyclone summaries
  and monthly cyclone track files can be obtained at the following
