Monthly Global Tropical Cyclone Summary November 1997
[Summaries and Track Data] [Prepared by Gary Padgett]


                             NOVEMBER, 1997

    Since we've changed some of the dissemination routes since the
 October summary was released, I'll repeat the introductory remarks
 for the benefit of any person who did not receive that summary.

    This is the second of what I hope will be many such monthly summaries
 chronicling tropical cyclone activity around the globe.  These should
 be considered as a very preliminary, "quick look" overview of the
 tropical cyclones that occur in each month.   The cyclone tracks (that
 will be provided separately) will generally be based upon operational
 warnings issued by the various tropical cyclone warning centers. The
 information contained therein may differ somewhat from the tracking
 and intensity information obtained from a "best track" file which is
 based on a detailed post-seasonal analysis of all available data.
 Information on where to find official "best track" files from the
 various warning centers will be passed along from time to time.

    A very, very special thanks is due to Dr. Chris Landsea of NOAA's
 Hurricane Research Division for asking me to write these summaries;
 for all his excellent and very helpful suggestions; and for offering
 to archive the summaries on AOML/HRD's computer system.  A very
 special thanks is due also to Dr. Jack Beven of TPC/TAFB for all the
 information and suggestions he passed along to me.    Two other
 persons who have been most helpful in providing me with information
 on South Pacific cyclones are Mark Kersemakers at the Fiji Tropical
 Cyclone Warning Centre and Steve Ready of the Meteorological Service
 of New Zealand.  A special thanks to these gentlemen also.

    Chris and I made the decision not to send the track files via
 e-mail.  They can be retrieved in the following manner:

      (a) FTP to: []
      (b) Login as: anonymous
      (c) For a password use your e-mail address
      (d) The files will be named with an obvious nomenclature--using
          October as an example:   oct97.tracks

    Both the summaries and the track files are standard text files
 created in DOS editor.  Download to disk and use a viewer such as
 Notepad or DOS editor to view the files.

    If anyone did not receive the October summary and would like a copy,
 please e-mail me a request and I'll be happy to forward it to them.

                        NOVEMBER HIGHLIGHTS

 --> Southern Mexican coast experiences another hurricane strike
 --> Southern Marianas and Vietnam struck by typhoons
 --> Most active November on record in the South Pacific
 --> Cook Islands and French Polynesia struck by cyclones


                           ACTIVITY BY BASINS

 ATLANTIC (ATL) - North Atlantic Ocean , Caribbean Sea , Gulf of Mexico

 Activity for November:  No tropical cyclones


 NORTHEAST PACIFIC (NEP) - North Pacific East of Longitude 180

 Activity for November:  1 tropical depression
                         1 hurricane

               Hurricane Rick (TC-19E)   7-10 November

      An area of disturbed weather a few hundred miles south of the
   Mexican coast had become sufficiently organized by 7 Nov that
   advisories were initiated on Tropical Depression 19-E at 2100 UTC
   with the system centered about 500 nm south of Manzanillo.  The
   depression drifted slowly and erratically northward for the next 24
   hrs with only slow intensification.  A ship located about 30 nm south
   of the center reported 25-kt winds and a pressure of 1006 mb at 1200
   UTC on 8 Nov.     By 2100 UTC the system had turned to a more
   northeasterly course and was upgraded to Tropical Storm Rick about
   250 nm southwest of Acapulco.

      Rick continued to intensify, becoming a hurricane at 0600 UTC on
   9 Nov when located about 125 nm south-southwest of Acapulco.  The
   hurricane was by this time moving on a more east-northeasterly course
   toward the same portion of the southern Mexican coast that was struck
   by Hurricane Pauline a month earlier.  Peak intensity of 75 kts and
   an estimated central pressure of 980 mb were attained at 1500 UTC when
   the hurricane was centered about 100 nm southeast of Acapulco.  The
   east-northeasterly movement continued, bringing the center of Rick
   onshore near Puerto Escondido at around 0300 UTC on 10 Nov with
   maximum sustained winds estimated near 65 kts.   At 2145 UTC on 9 Nov
   Puerto Escondido was reporting a sustained wind of 26 kts with gusts
   to 35 kts.  The last advisory on Rick at 2100 UTC on 10 Nov located
   the dissipating depression in the Mexican state of Chiapas near the
   Guatemalan border.

      Hurricane Rick brought over 10 inches of rain to the state of
   Oaxaca, causing mudslides and flash floods in some of the same areas
   severely affected by Pauline in October.  More than 2000 persons were
   left homeless, but no fatalities have been reported.

      The preliminary storm report on Hurricane Rick, which includes
   the analyzed "best track", can be found on the Tropical Prediction
   Center's website at>.

          Tropical Depression 04-C   31 October-1 November

      Tropical Depression 04-C, which had developed on 31 Oct, was
   located at 0300 UTC on 1 Nov about 425 nm southwest of Johnston Atoll
   and was already weakening.  By 1200 UTC the weak depression, with
   only 20-kt winds, was dissipating about 125 nm east of the dateline,
   far to the southwest of Johnston.


 NORTHWEST PACIFIC (NWP) - North Pacific West of Longitude 180

 Activity for November:  2 typhoons
                         1 supertyphoon

        Supertyphoon Keith (TC-29W)   27 October-8 November

      As the month of November opened, Supertyphoon Keith was located
   about 500 nm east-southeast of Guam moving on a west-northwesterly
   course toward the southern Marianas.   At 1800 UTC on 1 Nov Keith
   reached its estimated peak intensity of 160-kt sustained winds
   (1-min avg).   There were some reports stating that Keith appeared to
   be almost on a par with Supertyphoon Tip of October, 1979, in which a
   reconnaissance flight measured the world's lowest known sea level
   pressure of 870 mb.   Since no flights were made into Keith, the
   actual central pressure will never be known.

      The eye of Supertyphoon Keith moved through the Marianas Islands
   about 0600 UTC on 2 Nov (late afternoon local time), passing between
   the islands of Rota and Tinian with maximum sustained winds estimated
   at 150-155 kts.  Keith continued on its west-northwesterly heading
   until it recurved to the northeast early on 5 Nov about 650 nm west-
   northwest of Guam.  Peak winds had dropped to 110 kts by this time.
   Keith continued to accelerate to the east-northeast and slowly
   weakened. The storm passed only about 50 nm north of Iwo Jima at 
   0600 UTC on 7 Nov with maximum winds estimated at 75 kts.  Keith
   became extratropical about 1200 UTC on 8 Nov when located about 
   850 nm northwest of Wake Island.

      Dozens of homes and buildings on Rota and Tinian were reported to
   have been destroyed or heavily damaged, but no reports of deaths or
   injuries have been received by the author.

              Typhoon Linda (TC-30W)   31 October-9 November

      Tropical Depression 30-W, which had formed late on 31 Oct west
   of northern Borneo, reached tropical storm intensity by 0000 UTC
   on 1 Nov about 425 nm east-southeast of Ho Chi Minh City, Vietnam
   (formerly Saigon).  Linda moved on a westerly to west-northwesterly
   course which took it across the southern tip of Vietnam in the
   Mekong River delta region.  At the time of landfall the operational
   JTWC track assigns Linda maximum sustained winds of 55 kts.
   After emerging into the Gulf of Thailand, Linda reached minimal
   typhoon intensity of 65 kts at 1800 UTC on 2 Nov.  The typhoon
   continued across the Gulf of Thailand, making landfall again on the
   Malay Peninsula in southern Thailand, about 120 nm south-southwest
   of Bangkok.  As Linda approached land it began to weaken somewhat,
   with winds estimated at 50 kts near the time of landfall in Thailand.

      By 0000 UTC on 4 Nov the center was beginning to emerge into the
   Andaman Sea.  The subsequent history of Linda can be found in this
   summary in the section covering the North Indian Ocean basin.

      Information obtained by the author, which includes some reports
   from the Vietnamese Minister of Agriculture and Rural Development,
   placed the death toll in Vietnam at over 500, with over 3300 persons
   missing.  Most of the dead or missing were fishermen lost at sea.
   Many thousands of homes were damaged or destroyed, and more than
   450,000 hectares of rice paddies were inundated.    Linda was
   reportedly the deadliest typhoon to affect Vietnam since 1904.

               Typhoon Mort (TC-31W)   10-16 November

      Warnings were begun on Tropical Depression 31-W at 1800 UTC on
   10 Nov placing the developing system about 300 nm west-southwest
   of Guam with 25-kt winds.  The system was upgraded to Tropical
   Storm Mort 12 hrs later about 100 nm farther west.  Mort continued on
   a west-northwesterly track throughout most of its lifetime.  Typhoon
   status was reached at 1800 UTC on 12 Nov about 375 nm north-northwest
   of Palau.     Mort's winds never increased above minimal typhoon
   strength of 65 kts.  Late on 13 Nov the storm began to encounter
   strong upper-level shear.  The warning issued at 0000 UTC on 14 Nov
   abruptly downgraded the system to a minimal tropical storm with
   35-kt winds.  Mort at this time was located about 475 nm east of
   Manila.  Over the next couple of days, Mort re-intensified back to
   55 kts, but began to weaken again as it approached the island of
   Luzon.  The last warning on Mort at 0600 UTC on 16 Nov downgraded
   the storm to a 25-kt depression near Baler on the central coast of
   Luzon.  The dissipating system moved inland and dissipated over
   central Luzon.


 NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea

 Activity for November:  1 tropical cyclone of gale intensity
                         1 tropical cyclone of storm intensity
                         1 tropical cyclone of typhoon intensity

             Typhoon Linda (TC-30W)   31 October-9 November

      Tropical Storm Linda emerged into the Andaman Sea around 0000 UTC
   on 4 Nov, moving off the coast of Myanmar about 275 nm southeast of
   Yangan (formerly Rangoon).   Estimated maximum sustained winds at
   this time were 45 kts.  For the next several days Linda moved slowly
   and sometimes erratically on a general westerly to west-northwesterly
   track which took the storm through the Andaman Islands and into the
   Bay of Bengal proper.  Linda regained typhoon intensity on 6 Nov at
   1200 UTC when centered about 450 nm south of Chittagong, Bangladesh.
   Typhoon intensity persisted for only about 18 hrs, then the storm
   began to slowly weaken.  Linda moved slowly and erratically in the
   central Bay of Bengal as it weakened--the last warning being issued
   at 0600 UTC on 9 Nov.  The dissipating depression at this time was
   located about 450 nm south-southeast of Calcutta.

                   Tropical Cyclone 03-A   8-9 November

      Tropical Cyclone 03-A was a short-lived system of minimal tropical
   cyclone intensity which formed in the western Arabian Sea.  The first
   warning,  issued at 0600 UTC on 8 Nov,  located the cyclone about
   150 nm south of Socotra Island with 35-kt winds.  The system moved
   inland over the northeastern peninsula of Somalia around 0000 UTC on
   9 Nov.  Although subsequent warnings tracked the system northward
   back out over the Gulf of Aden, the final warning issued at 1800
   UTC stated that the system had dissipated over Somalia.

      No reports of any adverse effects of this cyclone have been
   received by the author.

                  Tropical Cyclone 04-A   10-14 November

      The second tropical cyclone in the Arabian Sea within less than a
   week was first classified as a depression at 0000 UTC on 10 Nov about
   550 nm south-southwest of Bombay.  Tropical Cyclone 04-A moved on a
   fairly smooth west-northwesterly course until around 0600 UTC on
   13 Nov, when it curved to the southwest from a location about 450 nm
   southeast of Masirah Island off the coast of Oman.   The system
   by this time was beginning to weaken due to the effects of strong
   vertical wind shear.

      Tropical Cyclone 04-A dissipated about 435 nm south-southeast of
   Masirah after 0000 UTC on 14 Nov.  Peak intensity of 55 kts maximum
   sustained winds was reached at 0600 UTC on 11 Nov with the storm
   centered about 535 nm southwest of Bombay.   During the time that the
   cyclone was near peak intensity, maximum wind estimates ran a little
   higher than usual for the given satellite T-numbers due to above-
   normal ambient pressures in the storm's vicinity.


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

 Activity for November:  No tropical cyclones


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

 Activity for November:  1 tropical cyclone of storm intensity **

   ** - possibly reached hurricane intensity -- was classified as a
        hurricane in warnings issued by JTWC

             Tropical Cyclone Nute (TC-05P)   18-21 November

      Tropical Cyclone Nute began in the Southwest Pacific Basin on
   11 Nov and was named by the Fiji TCWC at 1200 UTC when located
   far to the north of Vanuatu.  Nute crossed longitude 160E and
   entered the Brisbane TCWC's area of warning responsibility at
   1800 UTC on 19 Nov.  At this time the storm was located about
   475 nm west-northwest of Vila, Vanuatu.  Maximum 10-min avg winds
   at this time were 60 kts, but there is a possibility that the
   winds will be increased to hurricane force in post-storm analysis.
   A warning issued by the JTWC on Guam at this time reported maximum
   winds in Nute to be 70 kts (1-min avg).   Nute was at peak intensity
   about this time with its central pressure estimated at 975 mb.

      Nute did not move very far into Australian waters before it began
   to weaken and turn southward.  By late on 20 Nov (UTC) Nute had
   rapidly weakened due to strong vertical shear and entrainment of
   dry air, and Guam wrote the last warning on the system.  Brisbane
   downgraded Nute to a depression at 0000 UTC on 21 Nov but reported
   that a few gales remained in the southern semicircle.  The last
   warning issued at 1200 UTC placed the LOW about 375 nm west of
   Noumea, New Caledonia.


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

 Activity for November:  1 tropical cyclone of storm intensity
                         2 tropical cyclones of hurricane intensity

      The month of November continued the active streak which began in
   October.  According to Steve Ready of the New Zealand Meteorological
   Service, this was the most active month of November on record in
   the South Pacific.   Much of the information below was supplied
   by Steve and by Mark Kersemakers of the Fiji Meteorological Service.
   A special thanks to these gentlemen for their assistance.

        Tropical Cyclone Martin (TC-04P)   31 October-5 November

      Tropical Cyclone Martin had formed on 31 Oct a few hundred miles
   northwest of Samoa.  At 0000 UTC on 1 Nov the intensifying cyclone
   was centered about 250 nm west of Manihiki Atoll in the Northern
   Cooks, moving very slowly east-southeastward.  By 0600 UTC on 2 Nov
   the cyclone passed about 60 nm south of Manihiki with maximum winds
   estimated at 60 kts (10-min avg).  Continuing on to the southeast,
   Martin reached hurricane force at 1800 UTC when located about 165 nm
   southeast of the atoll.  As assessed by the Fiji TCWC, Martin reached
   peak intensity of 80 kts on 3 Nov around 1200 UTC about 300 nm west-
   northwest of Tahiti.

      Early on 4 Nov the cyclone began to weaken steadily and accelerated
   to the southeast, passing over 200 nm to the south of Tahiti. Warning
   responsibility was handed over to Wellington when the system crossed
   latitude 25S at 0600 UTC on 5 Nov.   The last warning available to
   the author (at 1200 UTC) placed the minimal tropical cyclone about
   750 nm southeast of Tahiti, or about 550 nm west of Pitcairn Island.

      Tropical Cyclone Martin was quite destructive on Manihiki Atoll.
   When the center was closest to the island, the AWS reported a lowest
   pressure of 994 mb, sustained winds of 39 kts (10-min avg), and a
   highest gust of 56 kts. However this was the last official report
   from the station before it was demolished by the storm surge. There
   were 10 known fatalities on Manihiki with 10 more persons reported
   missing (and presumed drowned).  Almost every building on the island
   was destroyed by the storm surge--even a concrete water tank broke
   under the onslaught of the waves.

      At its maximum intensity Martin passed near the westernmost islands
   in the Socitey group (Bellingshausan, Mopelia, and Scilly) where 8
   deaths were reported.

      Tracking positions contained in the warnings issued by the Naval
   Pacific Meteorology and Oceanography Center (NPMOC) at Pearl Harbor
   were in reasonable agreement with Fiji's, though not as close as with
   some other cyclones.  The highest 1-min sustained wind reported by
   NPMOC was 100 kts on 3 Nov, during which time Fiji's maximum 10-min
   avg wind was 80 kts.  Converting 100 kts to its 10-min equivalent
   yields 87 kts, or a difference of only 7 kts.  This is in very good
   agreement, considering the uncertainties inherent in estimating
   tropical cyclone intensities from satellite imagery.

            Tropical Cyclone Nute (TC-05P)   18-21 November

      The first bulletin on a developing tropical depression was issued
   by the Fiji TCWC at Nadi at 0000 UTC on 18 Nov, locating the system
   about 425 nm north-northwest of Vila, Vanuatu.  The depression moved
   southwestward and was upgraded to Tropical Cyclone Nute at 1200 UTC
   when located 450 nm northwest of Vila.  Nute continued to intensify
   as it moved to the southwest with maximum winds reaching 60 kts by
   0600 UTC on 19 Nov.  At 1800 UTC the storm crossed longitude 160E
   and entered the Australian region of warning responsibility.

      Warnings on Nute for the remainder of its life were issued by the
   Brisbane TCWC.    See the portion of this summary covering the
   Australian region for the history of Nute in that area.

            Tropical Cyclone Osea (TC-06P)   22-28 November

      Bulletins were begun on a new tropical depression at 0000 UTC on
   22 Nov located about 250 nm east-northeast of Manihiki Atoll in the
   Northern Cooks.    The depression remained weak and drifted very
   slowly southward for the next couple of days.  Warnings were begun
   by NPMOC at 1200 UTC on 23 Nov.   The system was moving very slowly
   on a southerly course when it was named by the Fiji TCWC on 24 Nov
   at 0000 UTC.  The first warning on Tropical Cyclone Osea placed the
   center about 200 nm east-southeast of Manihiki.

      Osea began to intensify and moved a little faster on a general
   southeasterly course.  Hurricane intensity was reached at 1200 UTC
   on 25 Nov about 300 nm west-northwest of Tahiti with peak winds of
   80 kts occurring from 0000 UTC to 1200 UTC on 26 Nov.  Thereafter
   the cyclone began to steadily weaken.   The center of Osea passed
   over 200 nm south of Tahiti around 0000 UTC on 28 Nov with winds
   of only 35 kts.  The last bulletin issued at 0600 UTC downgraded
   the system to a depression about 250 nm south-southeast of Tahiti.

      Cyclone Osea was quite destructive to some of the islands of
   French Polynesia.  Over 700 homes were destroyed or badly damaged
   on Maupiti, Bora-Bora, and Raiatea.  On Maupiti (pop. 1100) about
   95% of the infrastructure (including the town hall, two schools,
   and an airfield) were destroyed; while on Bora-Bora (pop. 4500)
   roughly 30% of the infrastructure was destroyed.  Very fortunately
   there was no loss of life reported from Tropical Cyclone Osea.

      Comparing tracking and intensity information issued by NPMOC
   to the official warnings from Nadi--the position coordinates were
   in excellent agreement.  There were several instances when NPMOC's
   maximum wind estimates (1-min avg) were somewhat less than Fiji's
   maximum 10-min avg winds; however the peak intensity estimates of
   90 kts (NPMOC) and 80 kts (Fiji) were in excellent agreement.
