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

                        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.   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.

Note: The center fix from the final SAB satellite bulletin at
07/1430 UTC places the center just inland from the coast of Iran,
whereas the final JTWC position at 07/1800 UTC is just offshore.
At 06/0600 UTC I chose to use IMD's MSW of 80 kts since it was more in
line with the consensus of Dvorak estimates from the several agencies.

The IMD estimate of 90 kts at 06/1200 UTC was equated with a T-number
of T4.5, and seems too high considering the fact that Gonu was weakening,
and given that on the previous day 970 hPa was matched with a MSW of
80 kts.

Note:  The IMD classified this system as a deep depression, implying
peak winds of 30 kts.  While JTWC assigned a peak 1-min avg of 35 kts,
neither JTWC nor AFWA assigned Dvorak T-numbers exceeding T2.0.  The only
bulletin available to the author with a Dvorak estimate of T2.5 was the
SAB bulletin issued at 22/0230 UTC.  However, Dr. Karl Hoarau performed
his own Dvorak analysis of the system and assigns a peak intensity of
45 kts at 22/0000 UTC, shortly before landfall in India.

The preceding comments apply only to the Bay of Bengal portion of this
system.  In its Arabian Sea phase the system was considerably stronger, 
and based on most Dvorak intensity estimates, microwave imagery, and at 
least one SLP observation a few hours after landfall, the storm was 
probably a Category 1 hurricane when it made landfall in Pakistan.  
IMD, who has official naming responsibility for the North Indian Ocean 
basin, again did not classify the system above deep depression status;
hence, they did not name the storm.  However, the Meteorological Service
of Pakistan applied the name Yemyin to the cyclone in their warnings,
and this was picked up by the press and given widespread dissemination.

              !!!!!!  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:

     http://www.nhc.noaa.gov>

     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:
