The above track is based on the "working" Best Track file taken from NHC's FTP site. Interest in the system centers on the night of 27-28 October when convection had been increasing slightly near the sheared center, and an ASCAT pass revealed the existence of 35-kt wind vectors. Advisories were almost initiated on what would have been Tropical Storm Shary, but since by the 28/0300 UTC advisory time the convection was beginning to wane and the center appeared to be somewhat elongated, the decision was made to wait and see if convective organization returned before upgrading. Continued weakening ensued so the system was not named. About 24 hours later another disturbance to the west became Tropical Storm Shary. As the above track shows, the existence of gales was substantiated, and the LOW did not appear to be frontal. There is a possibility that this system could be added as an unnamed tropical storm pending further analysis. ************************************************************************* Storm Name: SHARY Cyclone Number: 20 Basin: ATL Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 10 OCT 26 1800 21.5 N 52.0 W 1009 25 From working BT file 10 OCT 27 0000 21.7 N 52.3 W 1009 25 10 OCT 27 0600 21.9 N 52.7 W 1009 25 10 OCT 27 1200 22.2 N 53.1 W 1009 25 10 OCT 27 1800 22.6 N 54.0 W 1010 25 10 OCT 28 0000 22.9 N 55.3 W 1010 25 10 OCT 28 0600 23.5 N 56.7 W 1009 30 10 OCT 28 1200 24.1 N 58.7 W 1009 30 10 OCT 28 1800 25.6 N 61.2 W 1006 30 10 OCT 29 0000 26.8 N 62.7 W 1004 35 First adv on TS Shary 10 OCT 29 0600 28.1 N 64.6 W 1004 35 10 OCT 29 1200 29.3 N 65.9 W 1004 35 10 OCT 29 1800 30.2 N 65.8 W 1000 50 10 OCT 30 0000 31.3 N 64.3 W 994 60 10 OCT 30 0600 32.9 N 60.9 W 989 65 10 OCT 30 1200 35.1 N 57.2 W 989 65 10 OCT 30 1800 37.9 N 52.9 W 991 60 Final NHC advisory 10 OCT 31 0000 41.0 N 49.0 W 1000 45 Post-tropical 10 OCT 31 0600 44.0 N 43.0 W 1002 45 Note: The OPC High Seas warning for 31/1200 UTC did not reference any LOW which could be connected with Post-tropical Shary, so it appears that the former tropical cyclone was absorbed by an advancing cold front. ************************************************************************* Storm Name: TOMAS Cyclone Number: 21 Basin: ATL Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 10 OCT 26 1800 5.0 N 37.0 W 1009 25 Tropical disturbance 10 OCT 27 0000 5.3 N 38.5 W 1009 25 From working BT file 10 OCT 27 0600 5.5 N 40.0 W 1009 25 10 OCT 27 1200 5.8 N 41.5 W 1008 25 10 OCT 27 1800 6.0 N 43.0 W 1008 25 10 OCT 28 0000 6.4 N 44.8 W 1007 30 10 OCT 28 0600 6.8 N 46.8 W 1006 30 10 OCT 28 1200 7.2 N 48.6 W 1006 30 10 OCT 28 1800 7.7 N 50.4 W 1006 30 10 OCT 29 0000 8.3 N 52.2 W 1006 30 10 OCT 29 0600 9.0 N 53.8 W 1006 30 10 OCT 29 1200 9.7 N 55.4 W 1005 30 10 OCT 29 1800 10.8 N 56.8 W 998 35 10 OCT 30 0000 11.9 N 57.8 W 999 50 First advisory 2100Z 10 OCT 30 0600 12.7 N 58.9 W 997 55 Just south of Barbados 10 OCT 30 1200 13.1 N 60.1 W 993 60 10 OCT 30 1800 13.4 N 61.0 W 992 65 In St. Vincent Passage 10 OCT 31 0000 13.5 N 61.7 W 982 80 10 OCT 31 0600 13.8 N 62.4 W 982 85 10 OCT 31 1200 14.0 N 63.3 W 983 85 10 OCT 31 1800 14.2 N 64.3 W 994 65 10 NOV 01 0000 14.2 N 66.0 W 997 55 10 NOV 01 0600 13.9 N 67.1 W 1003 45 10 NOV 01 1200 13.6 N 68.2 W 1005 40 10 NOV 01 1800 13.4 N 69.2 W 1005 40 10 NOV 02 0000 13.5 N 70.3 W 1005 40 10 NOV 02 0600 13.5 N 71.3 W 1003 45 10 NOV 02 1200 13.4 N 72.2 W 1003 45 10 NOV 02 1800 13.4 N 74.2 W 1006 35 10 NOV 03 0000 13.6 N 74.8 W 1006 35 10 NOV 03 0600 13.4 N 75.3 W 1006 35 10 NOV 03 1200 13.9 N 75.7 W 1006 30 Downgraded at 0900Z 10 NOV 03 1800 14.8 N 74.8 W 1006 30 10 NOV 04 0000 15.2 N 75.1 W 1003 40 Upgraded at 2100Z 10 NOV 04 0600 15.6 N 76.0 W 1001 40 10 NOV 04 1200 15.9 N 76.0 W 998 45 10 NOV 04 1800 16.3 N 76.2 W 996 45 10 NOV 05 0000 17.0 N 75.7 W 993 50 10 NOV 05 0600 17.7 N 75.2 W 989 55 10 NOV 05 1200 18.7 N 74.7 W 987 75 Upgraded at 0900Z 10 NOV 05 1800 19.8 N 74.0 W 987 75 In Windward Passage 10 NOV 06 0000 20.4 N 73.1 W 994 65 10 NOV 06 0600 21.4 N 71.8 W 992 65 Just S of Caicos Is. 10 NOV 06 1200 22.6 N 70.9 W 991 55 Downgraded at 0900Z 10 NOV 06 1800 23.8 N 70.1 W 991 55 10 NOV 07 0000 24.9 N 69.7 W 986 70 10 NOV 07 0600 26.0 N 69.0 W 989 65 10 NOV 07 1200 25.8 N 69.6 W 997 50 10 NOV 07 1800 26.0 N 69.5 W 997 50 Final NHC advisory 10 NOV 08 0000 26.0 N 67.0 W 994 50 Post-tropical 10 NOV 08 0600 26.0 N 67.0 W 994 50 10 NOV 08 1200 26.0 N 66.0 W 997 50 10 NOV 08 1800 26.0 N 65.0 W 998 40 10 NOV 09 0000 27.0 N 62.0 W 998 30 10 NOV 09 0600 28.0 N 60.0 W 998 40 10 NOV 09 1200 30.0 N 59.0 W 1000 35 ************************************************************************* ************************************************************************* 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.

Following is some information on the peak winds measured by a SFMR instrument onboard a reconnaissance aircraft supplied by Dr. Karl Hoarau: "The more reliable was 169 knots at 1302Z and then 165 knots at 1318Z. The SFMR recorded 171 knots at 1113Z, 173 knots at 1203Z, 170 knots at 1303Z, 172 knots at 1317Z. But the quality code of 05 meant that the temperature, the dew point temperature and the SFMR were questionable. The 169 knots at 1302Z and then 165 knots at 1318Z had a good quality data. Moreover, the 700 hPa flight wind was at 190 knots. Using 90% of the flight wind, this gave a surface wind of 170 knots." A dropsonde released in the eyewall reported 174 kts at the surface, but the duration of this wind is unknown. These observations from the SFMR are of inestimable value, recording such high winds at the surface in a tropical cyclone. Hopefully, this will help to dispel the notion that no typhoon since STY Tip of 1979 has had winds exceeding 160 kts (several have had better satellite signatures). ************************************************************************* Storm Name: CHABA Cyclone Number: 16W Basin: NWP PAGASA Internal Name: KATRING JMA Tropical Storm Number: 1014 Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 10 OCT 20 0000 16.0 N 148.0 E 1006 25 10 OCT 20 1200 16.0 N 145.8 E 1004 30 10 OCT 20 1800 16.1 N 144.8 E 1004 30 10 OCT 21 0000 16.7 N 143.3 E 1004 30 10 OCT 21 0600 17.2 N 142.4 E 1002 30 10 OCT 21 1200 17.2 N 141.3 E 1002 25 30 JTWC warnings. 10 OCT 21 1800 17.3 N 139.8 E 1002 25 30 JMA: 17.4N/140.2E 10 OCT 22 0000 17.3 N 139.1 E 1002 25 30 10 OCT 22 0600 17.1 N 138.3 E 1002 25 30 10 OCT 22 1200 17.2 N 137.0 E 1004 25 30 10 OCT 22 1800 17.2 N 136.5 E 1004 25 30 10 OCT 23 0000 16.1 N 135.2 E 1004 25 30 JMA: 17.0N/136.0E 10 OCT 23 0600 16.2 N 133.7 E 1002 25 30 JMA: 16.0N/135.1E 10 OCT 23 1200 16.5 N 132.8 E 1004 25 30 JMA: 15.3N/134.4E 10 OCT 23 1800 15.4 N 133.0 E 1004 30 30 JMA: 14.8N/133.8E 10 OCT 24 0000 15.4 N 132.9 E 1004 30 30 JMA: 14.8N/132.8E 10 OCT 24 0600 15.5 N 132.6 E 1000 30 30 10 OCT 24 1200 15.7 N 132.1 E 996 35 35 10 OCT 24 1800 16.8 N 131.2 E 996 35 35 10 OCT 25 0000 16.9 N 130.8 E 992 45 40 10 OCT 25 0600 17.4 N 130.4 E 985 55 50 10 OCT 25 1200 18.0 N 129.9 E 980 60 55 10 OCT 25 1800 19.0 N 129.4 E 975 65 60 10 OCT 26 0000 19.5 N 129.2 E 970 70 70 10 OCT 26 0600 19.9 N 128.6 E 965 70 70 10 OCT 26 1200 20.2 N 128.2 E 965 75 70 10 OCT 26 1800 20.4 N 127.5 E 965 90 70 10 OCT 27 0000 20.7 N 128.0 E 955 95 75 10 OCT 27 0600 21.7 N 127.8 E 955 100 75 10 OCT 27 1200 22.4 N 128.0 E 950 110 85 10 OCT 27 1800 23.3 N 128.3 E 945 110 85 10 OCT 28 0000 24.2 N 128.6 E 945 115 85 10 OCT 28 0600 24.8 N 129.1 E 935 115 90 10 OCT 28 1200 25.7 N 130.0 E 935 110 90 10 OCT 28 1800 26.4 N 130.8 E 945 105 80 10 OCT 29 0000 27.2 N 131.6 E 960 95 70 10 OCT 29 0600 28.3 N 132.7 E 965 90 65 10 OCT 29 1200 29.3 N 134.1 E 970 80 60 South of Japan 10 OCT 29 1800 30.6 N 135.7 E 975 75 60 10 OCT 30 0000 32.0 N 137.2 E 980 70 55 10 OCT 30 0600 33.6 N 139.0 E 985 60 55 Extratropical 10 OCT 30 1200 35.3 N 142.2 E 994 45 50 JMA: 35.3N/142.2E 10 OCT 30 1800 36.0 N 144.0 E 998 50 JMA High Seas bulletins 10 OCT 31 0000 37.0 N 147.0 E 1000 10 OCT 31 0600 38.0 N 149.0 E 1008 10 OCT 31 1200 38.0 N 150.0 E 1012 10 OCT 31 1800 39.0 N 150.0 E 1012 10 NOV 01 0000 40.0 N 151.0 E 1012 ************************************************************************* Storm Name: None Cyclone Number: 17W Basin: NWP PAGASA Internal Name: None JMA Tropical Storm Number: None Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 10 OCT 20 0600 16.0 N 163.0 E 1010 25 JMA bulletins 10 OCT 20 1200 16.0 N 162.0 E 1010 25 10 OCT 20 1800 17.0 N 161.0 E 1008 25 10 OCT 21 0000 19.1 N 160.1 E 1008 30 10 OCT 21 0600 19.9 N 158.6 E 1008 30 10 OCT 21 1200 20.3 N 157.2 E 1006 30 10 OCT 21 1800 20.8 N 156.0 E 1006 30 30 10 OCT 22 0000 21.1 N 155.5 E 1008 30 30 10 OCT 22 0600 21.7 N 154.8 E 1006 30 30 10 OCT 22 1200 22.4 N 153.8 E 1006 30 30 10 OCT 22 1800 22.0 N 152.9 E 1004 30 30 10 OCT 23 0000 22.1 N 153.7 E 1006 30 30 10 OCT 23 0600 22.2 N 154.0 E 1006 30 30 10 OCT 23 1200 22.8 N 154.9 E 1006 25 30 JTWC Final 10 OCT 23 1800 23.0 N 155.0 E 1006 25 10 OCT 24 0000 22.0 N 155.0 E 1008 25 10 OCT 24 0600 22.0 N 155.0 E 1008 25 10 OCT 24 1200 21.0 N 155.0 E 1008 25 10 OCT 24 1800 21.0 N 154.0 E 1008 25 10 OCT 25 0000 21.0 N 154.0 E 1008 25 10 OCT 25 0600 22.0 N 153.0 E 1008 25 10 OCT 25 1200 23.0 N 153.0 E 1010 25 10 OCT 25 1800 23.0 N 153.0 E 1010 25 10 OCT 26 0000 24.0 N 153.0 E 1012 25 10 OCT 27 0000 28.0 N 153.0 E 1012 25 Reinstated 10 OCT 27 0600 29.0 N 153.0 E 1010 25 Note: After dismissing this system as a weak tropical depression after 26/0000 UTC, JMA briefly reinstated it for two warning cycles at 27/0000 UTC.

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.

Kevin Boyle, of Stoke-on-Trent, UK, will be preparing the tracks for Northwest Pacific basin tropical cyclones during the most active part of the NWP season from June through December. Michael Bath, of McLeans Ridges, New South Wales, Australia, is now preparing the track files for Australian Region and South Pacific tropical cyclones. Also, Steve Young sends me tracks with data for the pre-warning and post-warning stages of tropical cyclones in all basins, prepared primarily from NCEP re-analysis data or else taken from NRL files. A very special thanks is due to Kevin, Michael and Steve for their assistance. ************************************************************************* SOURCES OF TROPICAL CYCLONE INFORMATION The purpose of this section is to list some websites where many and varied types of tropical cyclone information are archived. Many readers will know about these already, but for the benefit of those who don't, I wanted to include them. (1) Aircraft Reconnaissance Information --------------------------------------- Various types of messages from reconnaissance aircraft may be retrieved from the following FTP site: Information regarding how to interpret the coded reconnaissance messages may be found at the following URL: Links are also included to websites with further information about the U. S. Air Force 53rd Weather Reconnaissance Squadron and the NOAA Air- craft Operations Center. (2) Archived Advisories ----------------------- All the advisory products (public advisories, forecast/advisories, strike probabilities, discussions, various graphics) issued by TPC/NHC are archived on TPC's website. For the current year (using 2004 as an example), the archived products can be found at: Links to tropical products archives for earlier years are available at the following URL: JTWC warnings for past storms are archived on the NRL Monterrey website: On the NRL site, the link to past years can be found in the upper left corner of the screen. I am not aware at the moment of any other TCWC which archives all its tropical cyclone warning/advisory products for public access, but if I learn of any, I will add them to this list. (3) Satellite Imagery --------------------- Satellite images of tropical cyclones in various sensor bands are available on the NRL Monterrey and University of Wisconsin websites, courtesy of Jeff Hawkins and Chris Velden and their associates. The links are: On the NRL site, the link to past years can be found in the upper left corner of the screen. For the CIMSS site, a link to data archives is located in the lower left portion of the screen. Additional tropical satellite imagery, along with looping ability for composite microwave imagery for the Western Hemisphere north of the equator, can be found at: (1) For the Eastern North Pacific: (2) For the Atlantic, Gulf of Mexico and Caribbean Sea: (4) Cyclone Tracking Information -------------------------------- There is a U. S. Navy site that tracks tropical cyclones at 6-hourly intervals which often includes pre and post-advisory positions. The link to the site is: Steve Young has compiled many of these tracks onto a single webpage which is very user-friendly: ************************************************************************* !!!!!! 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: 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: SPECIAL NOTE: Back issues of the global tropical cyclone summaries and monthly cyclone track files can be obtained at the following websites: PREPARED BY: Gary Padgett garyp@alaweb.com Kevin Boyle michaelpace@btinternet.com Michael Bath mbath@ozemail.com.au SIGNIFICANT CONTRIBUTIONS BY: Michael V.
