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. ************************************************************************* Storm Name: BABIOLA Cyclone Number: 04S Basin: SIO Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 00 JAN 03 0600 12.0 S 82.4 E 1001 25 Meteo France Warning 00 JAN 03 1200 12.3 S 82.2 E 1001 25 25 JTWC-1630Z: 13.2S,82.2E 00 JAN 03 1800 12.5 S 81.8 E 1001 25 00 JAN 04 0000 12.6 S 81.6 E 1000 25 00 JAN 04 0600 12.4 S 81.7 E 999 25 00 JAN 04 1200 12.0 S 82.3 E 999 30 25 JTWC Formation Alert 00 JAN 04 1800 11.7 S 82.6 E 999 25 00 JAN 05 0000 11.5 S 82.9 E 999 25 00 JAN 05 0600 10.4 S 84.4 E 999 25 00 JAN 05 1200 11.5 S 84.0 E 999 30 25 JTWC Formation Alert 00 JAN 05 1800 12.0 S 83.9 E 999 35 25 JTWC: 12.2 S, 82.8 E 00 JAN 06 0000 12.0 S 82.8 E 997 30 00 JAN 06 0600 12.6 S 81.7 E 994 45 35 00 JAN 06 1200 13.2 S 81.7 E 994 35 00 JAN 06 1800 13.7 S 80.5 E 994 45 35 00 JAN 07 0000 14.1 S 79.6 E 994 35 00 JAN 07 0600 14.4 S 78.7 E 988 50 43 00 JAN 07 1200 15.1 S 77.6 E 985 50 00 JAN 07 1800 15.7 S 75.8 E 980 55 55 00 JAN 08 0000 15.7 S 75.0 E 978 55 00 JAN 08 0600 16.2 S 73.3 E 976 65 57 00 JAN 08 1200 16.9 S 72.0 E 965 70 00 JAN 08 1800 17.1 S 70.9 E 960 75 75 00 JAN 09 0000 17.5 S 70.1 E 960 75 00 JAN 09 0600 18.3 S 68.9 E 960 75 75 00 JAN 09 1200 18.8 S 67.9 E 954 80 00 JAN 09 1800 19.6 S 67.6 E 954 90 80 00 JAN 10 0000 20.3 S 67.2 E 954 80 00 JAN 10 0600 20.6 S 67.2 E 954 90 80 00 JAN 10 1200 21.5 S 67.0 E 956 80 00 JAN 10 1800 22.0 S 67.0 E 965 65 70 JTWC: 22.6 S, 67.6 E 00 JAN 11 0000 23.0 S 67.2 E 970 65 00 JAN 11 0600 23.6 S 67.7 E 980 45 55 JTWC: 23.7 S, 68.4 E 00 JAN 11 1200 24.8 S 68.4 E 985 50 00 JAN 11 1800 25.4 S 68.8 E 990 35 45 00 JAN 12 0000 26.7 S 69.4 E 990 45 00 JAN 12 0600 27.7 S 70.1 E 995 25 40 See Note 00 JAN 12 1200 28.5 S 71.3 E 995 40 " 00 JAN 12 1800 29.5 S 72.3 E 998 30 Note: Winds to 40 kts forecast to be occurring up to 120 nm from center in southeast quadrant. ************************************************************************* Storm Name: Trop.

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. ************************************************************************* Storm Name: CONNIE Cyclone Number: 08S Basin: SIO Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 00 JAN 25 0600 15.0 S 56.0 E 999 25 Meteo France Warning 00 JAN 25 1200 15.1 S 55.1 E 997 30 30 JTWC Formation Alert 00 JAN 25 1800 15.2 S 55.2 E 991 35 40 JTWC: 15.7 S, 56.3 E 00 JAN 26 0000 15.2 S 55.4 E 991 35 40 00 JAN 26 0600 14.8 S 55.3 E 988 35 45 00 JAN 26 1200 14.4 S 55.3 E 988 45 45 00 JAN 26 1800 14.2 S 55.7 E 988 55 45 00 JAN 27 0000 14.6 S 55.6 E 986 60 45 00 JAN 27 0600 15.2 S 56.4 E 975 65 60 00 JAN 27 1200 15.6 S 56.5 E 955 85 80 00 JAN 27 1800 16.1 S 56.8 E 940 115 90 00 JAN 28 0000 16.4 S 57.0 E 940 115 90 00 JAN 28 0600 16.6 S 57.1 E 938 110 90 00 JAN 28 1200 17.0 S 57.0 E 938 110 90 00 JAN 28 1800 17.7 S 56.6 E 928 105 100 00 JAN 29 0000 18.1 S 56.2 E 930 95 100 00 JAN 29 0600 18.9 S 55.2 E 930 90 100 00 JAN 29 1200 19.8 S 54.5 E 950 80 85 00 JAN 29 1800 20.9 S 53.7 E 960 80 80 00 JAN 30 0000 22.0 S 53.0 E 968 70 70 00 JAN 30 0600 23.1 S 51.6 E 970 65 70 00 JAN 30 1200 24.4 S 50.6 E 972 60 00 JAN 30 1800 25.5 S 50.2 E 976 60 55 00 JAN 31 0000 26.5 S 50.0 E 976 55 00 JAN 31 0600 27.5 S 50.5 E 980 55 55 00 JAN 31 1200 28.6 S 51.1 E 980 55 See Note 00 JAN 31 1800 29.7 S 51.7 E 985 65 50 00 FEB 01 0000 30.5 S 53.4 E 985 50 MFR: Final Warning 00 FEB 01 0600 31.3 S 52.3 E 55 JTWC Warning 00 FEB 01 1800 32.1 S 53.3 E 35 " 00 FEB 02 0600 33.4 S 54.5 E 25 " Note: Position coordinates for this time were interpolated from the previous and following positions. ************************************************************************* ************************************************************************* 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.

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. ************************************************************************* Storm Name: Tropical Depression Cyclone Number: 08F Basin: SWP Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 00 JAN 20 0600 14.0 S 172.0 W 1003 25 See Note #1 00 JAN 20 2100 14.0 S 172.0 W 1000 25 00 JAN 21 2100 16.5 S 173.8 W 1000 25 00 JAN 22 0600 18.0 S 175.0 W 1000 25 00 JAN 22 2100 18.6 S 176.8 W 1004 25 00 JAN 23 0600 18.9 S 177.4 W 1003 25 00 JAN 23 1800 19.0 S 175.0 W 998 30 00 JAN 24 0000 20.1 S 175.1 W 998 30 00 JAN 24 0600 20.8 S 175.0 W 997 35 See Note #2 00 JAN 24 1200 21.5 S 174.5 W 997 35 00 JAN 24 1800 22.5 S 173.5 W 996 35 00 JAN 25 0000 22.5 S 173.3 W 997 35 00 JAN 25 0600 23.2 S 172.5 W 996 35 00 JAN 25 1200 23.6 S 171.8 W 997 35 00 JAN 25 1800 24.4 S 171.0 W 997 35 00 JAN 26 0000 25.1 S 171.0 W 997 35 00 JAN 26 0500 26.0 S 168.0 W 1000 40 Wellington Warning 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. ************************************************************************* Storm Name: JO (09F) Cyclone Number: 07P Basin: SWP Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 00 JAN 23 0000 14.0 S 172.0 E 997 25 00 JAN 23 0600 14.0 S 172.0 E 997 25 00 JAN 23 1200 16.2 S 172.6 E 997 30 00 JAN 23 1800 17.3 S 172.3 E 995 30 00 JAN 24 0000 18.2 S 173.3 E 995 40 35 JTWC: 17.5 S, 173.1 E 00 JAN 24 0300 18.0 S 173.2 E 995 40 Named as a TC 00 JAN 24 0600 18.4 S 173.1 E 992 40 00 JAN 24 1200 19.6 S 173.3 E 992 45 40 00 JAN 24 1800 19.4 S 173.3 E 985 50 00 JAN 25 0000 19.8 S 174.6 E 985 50 50 00 JAN 25 0600 21.3 S 174.6 E 985 50 00 JAN 25 1200 21.7 S 175.0 E 980 65 55 00 JAN 25 1800 22.7 S 176.0 E 980 55 00 JAN 26 0000 23.2 S 176.8 E 975 65 60 00 JAN 26 0600 24.0 S 177.9 E 975 60 00 JAN 26 1200 25.1 S 179.0 E 975 65 60 00 JAN 26 1800 26.3 S 180.0 E 978 60 Wellington Warnings 00 JAN 27 0000 27.4 S 178.8 W 978 60 60 | 00 JAN 27 0600 28.3 S 176.9 W 980 60 | 00 JAN 27 1200 30.0 S 175.0 W 984 55 | 00 JAN 27 1800 29.9 S 170.7 W 984 55 | 00 JAN 28 0000 31.8 S 165.6 W 984 55 v 00 JAN 28 0600 33.0 S 164.0 W 985 55 Extratropical ************************************************************************* ************************************************************************* *************************************************************************
