The portion of the track from 1200 UTC on 29 Nov through 0000 UTC on 1 Dec was based primarily on information sent to me by John Wallace. This gale center was mentioned in the Tropical Weather Outlooks issued by TPC/NHC from 24-30 Nov. On 30 Nov, the last day of the official Atlantic Hurricane Season, the system appeared to be developing significant tropical characteristics, but this trend was soon halted and the LOW began to slowly weaken. ************************************************************************* ************************************************************************* NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180 NOTE: The tracking information for Northwest Pacific Basin tropical cyclones is based primarily upon operational warnings from the Joint Typhoon Warning Center of the U.S. Air Force and Navy at Pearl Harbor, Hawaii. Comparisons were made with track coordinates given in advisories from the meteorological services of Japan (JMA) and the Philippines (PAGASA). In general, whenever the center position differed by more than 40-50 nm from JTWC's, an entry was made in the Remarks column. The 1-min avg MSW were taken from the JTWC advisories while the 10-min avg MSW were obtained from PAGASA's advisories if the storm was in PAGASA's area of responsibility; otherwise, they were gleaned from JMA's advisories or high seas forecasts. In a few cases the 10-min MSW given by PAGASA and JMA did not agree; in those cases I reported the higher value. The estimates of central pressure were obtained from JMA's advisories. Michael V. Padua, owner of the Typhoon '99 webpage sent me the PAGASA and JMA tracks for these systems--a special thanks to Michael for his assistance. ************************************************************************* Storm Name: Tropical Depression Cyclone Number: 28W Basin: NWP Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 99 NOV 05 0600 19.6 N 147.9 E 1004 30 JMA Warning 99 NOV 05 1200 18.6 N 145.9 E 1004 30 " 99 NOV 05 1800 18.1 N 146.2 E 1004 30 30 JMA: 18.6 N, 147.7 E 99 NOV 06 0000 18.2 N 146.1 E 1004 30 30 JMA: 19.5 N, 147.5 E 99 NOV 06 0600 17.7 N 145.6 E 30 See Note 99 NOV 06 1200 16.7 N 145.3 E 1002 25 30 JMA: 22.9 N, 149.5 E 99 NOV 06 1800 23.7 N 151.0 E 1000 30 JMA Warning - See Note 99 NOV 07 0000 25.7 N 151.6 E 1000 30 " 99 NOV 07 0600 26.0 N 151.0 E 1004 25 " 99 NOV 07 1200 27.0 N 153.0 E 1004 25 " 99 NOV 07 1800 28.0 N 155.0 E 1004 25 " Note: This is most perplexing! Initially JMA was certainly tracking the same LLCC as JTWC, but from 06/1200 UTC it appears that JMA was following another LLCC. Since I don't have any JMA information at 0600 UTC and since, unfortunately, JMA doesn't have any numbering or otherwise identification scheme for tropical depressions, I have no idea exactly what lies behind this huge discrepancy. Since the 1200 UTC warning was the last from JTWC, the coordinates from that point forward represent whatever it was that JMA was tracking. Perhaps this wasn't the best procedure to follow, but hopefully this explains it adequately. ************************************************************************* Storm Name: FRANKIE/SENDANG Cyclone Number: 29W Basin: NWP Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 99 NOV 06 0600 11.0 N 134.9 E 25 99 NOV 06 1200 11.6 N 132.9 E 30 99 NOV 06 1800 10.9 N 131.7 E 1002 25 30 PAGASA: 11.0 N, 134.0 E 99 NOV 07 0000 10.8 N 130.8 E 1002 25 30 PAGASA: 11.3 N, 133.3 E 99 NOV 07 0600 10.2 N 129.5 E 1000 25 30 PAGASA: 11.5 N, 129.7 E 99 NOV 07 1200 10.2 N 128.6 E 1000 25 30 PAGASA: 11.5 N, 127.6 E 99 NOV 07 1800 10.9 N 126.9 E 1000 25 30 PAGASA: 12.2 N, 125.5 E 99 NOV 08 0000 11.4 N 126.0 E 1000 30 40 PAGASA: 11.7 N, 125.7 E 99 NOV 08 0600 12.3 N 124.5 E 998 35 40 Over island of Samar 99 NOV 08 1200 12.5 N 122.5 E 994 35 40 PAGASA: 12.2 N, 123.5 E 99 NOV 08 1800 12.4 N 122.5 E 996 30 40 In Central Philippines 99 NOV 09 0000 12.1 N 122.7 E 30 30 99 NOV 09 0600 12.3 N 123.3 E 30 25 99 NOV 09 1200 12.6 N 123.4 E 25 99 NOV 09 1800 12.8 N 123.5 E 25 99 NOV 10 0000 12.8 N 123.6 E 20 Note: The 10-min avg MSW estimates for this system were all taken from PAGASA warnings since JMA did not consider Frankie/Sendang to have reached tropical storm intensity. ************************************************************************* Storm Name: GLORIA/TRINING (9922) Cyclone Number: 30W Basin: NWP Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 99 NOV 13 0600 14.3 N 131.3 E 25 99 NOV 13 1200 15.5 N 131.5 E 1002 30 30 99 NOV 13 1800 16.2 N 131.7 E 1000 30 30 99 NOV 14 0000 17.7 N 132.6 E 998 30 30 PAGASA: 17.8 N, 130.7 E 99 NOV 14 0600 18.5 N 130.4 E 996 40 35 JMA: 19.0 N, 130.9 E 99 NOV 14 1200 20.0 N 130.3 E 994 45 40 99 NOV 14 1800 21.0 N 130.5 E 985 45 45 99 NOV 15 0000 22.3 N 131.3 E 985 45 45 99 NOV 15 0600 24.0 N 132.0 E 980 45 50 99 NOV 15 1200 25.7 N 134.1 E 980 40 50 JMA: 25.5 N, 133.3 E 99 NOV 15 1800 27.6 N 137.6 E 980 65 50 See Note 99 NOV 16 0000 29.9 N 141.4 E 980 65 50 JMA: 30.0 N, 142.1 E 99 NOV 16 0600 32.3 N 146.1 E 980 55 50 JMA: 32.5 N, 147.1 E 99 NOV 16 1200 35.3 N 152.9 E 990 45 JMA Wrng/Extratropical Note: The sudden increase in JTWC's MSW estimate from 40 kts to 65 kts suggests that quite likely the 40-kt value at 15/1200 UTC was too low. ************************************************************************* ************************************************************************* ADDITIONAL TRACKS for NORTHWEST PACIFIC BASIN TROPICAL CYCLONES The following tracks are for three interesting systems which occurred in the Northwest Pacific basin during November and for which tropical cyclone warnings were not issued. With the exception of the first, the tracks were supplied by Dr. Mark Lander, a professor at the Water and Environmental Institute of the Pacific at the University of Guam. >From 1988 to 1998, Dr. Lander (who earned his Doctorate from the University of Hawaii in 1986) was funded by the Office of Naval Research to conduct research on tropical cyclones. During much of this time Mark worked at JTWC alongside the forecasters and satellite analysts, helping them to decide what basic research could best help them solve some of the problems encountered in their day-to-day work. In keeping with the policy I established a few months ago, I have chosen to unofficially refer to these systems with letters of the Greek alphabet. These Greek letter designations are just for the purpose of having some "handle" by which to refer to interesting systems which are both unnamed and unnumbered. Any person doing further research or analysis on them is free to use the names if they choose--they need not feel compelled to do so. ************************************************************************* Storm Name: "ZETA" Cyclone Number: None Basin: NWP Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 99 NOV 02 0600 10.5 N 109.5 E 1008 15 See Note 99 NOV 03 0600 9.0 N 109.0 E 1007 15 99 NOV 04 0600 9.0 N 110.7 E 1005 15 99 NOV 04 2230 12.0 N 109.5 E See Note 99 NOV 05 0600 11.0 N 111.0 E 1003 20 Note: No regular warnings were issued by JTWC on this system, which was a monsoon depression.

Likewise, the MSW values given above were taken from the STWOs. According to Dr. Lander, gale-force winds were occurring in the primary cloud band to the north and east of the LLCC and were probably nearing gale-force near the core at landfall. ************************************************************************* Storm Name: "ETA" Cyclone Number: None Basin: NWP Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 99 NOV 08 0000 10.0 N 160.0 E 20 99 NOV 08 0600 10.6 N 159.0 E 25 99 NOV 08 1200 11.3 N 158.1 E 25 99 NOV 08 1800 12.1 N 157.5 E 25 99 NOV 09 0000 13.0 N 156.8 E 25 99 NOV 09 0600 13.8 N 156.3 E 25 99 NOV 09 1200 14.6 N 155.7 E 30 99 NOV 09 1800 15.4 N 155.0 E 30 99 NOV 10 0000 16.2 N 154.4 E 30 99 NOV 10 0600 17.5 N 153.8 E 30 99 NOV 10 1200 19.2 N 153.5 E 30 99 NOV 10 1800 21.0 N 153.9 E 30 99 NOV 11 0000 22.5 N 154.5 E 30 99 NOV 11 0600 24.3 N 155.6 E 30 Merges with shear line 99 NOV 11 1200 25.8 N 157.7 E 30 99 NOV 11 1800 26.7 N 159.8 E 30 99 NOV 12 0000 27.5 N 162.0 E 30 99 NOV 12 0600 28.1 N 164.0 E 30 99 NOV 12 1200 28.2 N 165.4 E 35 Subtropical storm 99 NOV 12 1800 28.3 N 166.2 E 35 99 NOV 13 0000 28.4 N 166.5 E 40 99 NOV 13 0600 28.7 N 166.7 E 40 99 NOV 13 1200 28.8 N 167.0 E 40 99 NOV 13 1800 29.0 N 167.2 E 40 99 NOV 14 0000 29.2 N 167.5 E 45 99 NOV 14 0600 29.5 N 168.0 E 45 99 NOV 14 1200 29.9 N 168.9 E 45 99 NOV 14 1800 30.5 N 170.2 E 50 99 NOV 15 0000 31.2 N 172.0 E 55 99 NOV 15 0600 32.0 N 173.8 E 60 Peak intensity 99 NOV 15 1200 33.2 N 176.2 E 55 99 NOV 15 1800 34.6 N 178.2 E 50 99 NOV 16 0000 35.7 N 179.6 W 45 99 NOV 16 0600 35.9 N 177.2 W 45 99 NOV 16 1200 35.6 N 174.2 W 40 Note: This system did not reach tropical storm intensity while still classifiable as a tropical depression.

This system was likely more of a hybrid depression than purely tropical. ************************************************************************* Storm Name: Depression Cyclone Number: None Basin: SWP Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 99 NOV 13 0000 20.0 S 148.4 W 1003 35 See Note 99 NOV 13 0600 21.5 S 147.0 W 1003 35 99 NOV 13 1200 23.5 S 149.0 W 998 35 99 NOV 13 1800 24.0 S 149.0 W 996 40 99 NOV 14 0000 25.0 S 149.0 W 995 35 99 NOV 14 0600 26.0 S 149.0 W 997 40 99 NOV 14 1200 26.0 S 151.0 W 998 35 Weakening Note: This system was never referred to in warnings from Fiji as a tropical depression, but only as a depression, and from 13/1800 UTC on, it was referred to simply as a LOW. As with the previous system, this disturbance was likely a hybrid or even primarily baroclinic sort of depression. ************************************************************************* ************************************************************************* *************************************************************************
