              GLOBAL TROPICAL CYCLONE TRACKS - JANUARY 2000


  SOUTH INDIAN OCEAN (SIO) - South Indian Ocean West of Longitude 90E

  NOTE:  The tracking coordinates, 10-min avg MSW, and estimates of
         central pressure were obtained from the RSMC La Reunion's
         advisories, while the 1-min avg MSW were taken from JTWC's
         warnings.

         A special thanks is due to Patrick Hoareau of Rennes, France,
         (and a former resident of La Reunion) for preparing the track
         for Tropical Cyclones Babiola and Connie.      Patrick is a
         dedicated enthusiast and student of tropical cyclones and quite
         a knowledgeable chap about many aspects of the storms.   Also,
         a special thanks to Philippe Caroff of the La Reunion TCWC for
         sending me the information on Tropical Disturbance 03.

Note:  The only reason for including this system is that MFR issued
three warnings on it, numbering it as Tropical Disturance 03.  Since
there was an 11-day gap between the second and third warnings, I went
back and gleaned some information from JTWC's daily Significant Tropical
Weather Outlooks.     Apparently disturbed weather persisted in the
Mozambique Channel for a rather extended period.    JTWC dropped the
system on 17 Jan but began mentioning an area of disturbed weather in
the Channel again on 22 Jan.  Apparently there was some continuity with
the earlier system since MFR maintained the same disturbance number for
the latter warning.

AUSTRALIAN REGION (AUS) - From Longitude 90E Eastward to Longitude 160E

NOTE:  The tracking information presented below was obtained from
       operational warnings issued by the Tropical Cyclone Warning
       Centres at Perth, Western Australia; Darwin, Northern Territory;
       and Brisbane, Queensland.    JTWC warnings were utilized for
       making comparisons and for supplying information for times when 
       the Australian warnings were unavailable.   The 10-min MSW values
       were obtained from the Australian warnings while the 1-min MSW 
       values were assigned by JTWC.

       The tropical cyclone warnings from Perth report the analyzed
       cyclone positions at 0400, 1000, 1600, and 2200 UTC instead of
       the more familiar 0000, 0600, 1200, and 1800 UTC utilized by most
       TC warning agencies.

       A special thanks is due to Matthew Saxby of Queanbeyan, New
       South Wales, Australia, for sending me tabulated tracks of the
       Australian centres' tracking information.  Matthew is also a very
       knowledgeable and dedicated tropical cyclone enthusiast.

SOUTHWEST PACIFIC (SWP) - South Pacific Ocean East of Longitude 160E

NOTE:  The tracking and intensity information for Southwest Pacific
       Basin tropical cyclones was taken from real-time operational
       warnings issued by the Nadi TCWC, Fiji for positions north of
       25S and from the Wellington, New Zealand office for positions
       south of 25S.     Warnings from JTWC (west of 180) and from
       NPMOC (east of 180) were utilized for the purpose of making
       comparisons and for supplying information for times when the
       Nadi or Wellington warnings were unavailable.  The 10-min avg
       MSW values were taken from the Fiji or New Zealand warnings
       while the 1-min avg MSW values were obtained from the JTWC or
       NPMOC warnings.

       A special thanks to Alipate Waqaicelua, Chief Forecaster at the
       Nadi, Fiji, TCWC for sending me summaries and tabulated tracks
       of Tropical Cyclones Iris and Jo.

Note:  During the pre-cyclone tropical depression stage, gales were
occurring only in the northeastern semicircle.   The final warning at
10/1800 UTC, which downgraded Iris back to a depression, indicated that
some gales were still occurring in the eastern semicircle.   It should
be noted that objective (digital) Dvorak analysis yielded T-numbers
up to T6.5 at one point (this from Mark Lander), and a Satellite Bulletin
from JTWC indicated that IR analysis yielded a T-number of T6.0 while
the Dvorak rating based upon visible imagery was T4.0.

Note #1: 10-min MSW values prior to the first warning at 23/1800 UTC are
my estimates based upon the reported pressure and the fact that regular
warnings were not being issued.

Note #2: Gales were in the southeastern semicircle only but were reported
to be occurring within 40 nm of center.
