Hurricane over hilly terrain of Baja California for 36 hours and couldnít have 
maintained hurricane intensity.  System dissipates before reaching southern 
California and best track change smoothes the dissipation stage.

Change to make the Great Hurricane of 1959 become a Cat 5 over water instead of 
over land.  Kept intensity inland the same because of 135+ kt wind report in 
Manzanillo.  May have been stronger than 140 kt offshore.

Recommend deleting as a landfall.  MWL states that Hyacinth rapidly dissipated 
as it approached the coast.  Original track never brought it inland, even after 
extrapolation in the 1970s.  Suggested changes show a smooth dissipation and 
keep with general intensity assignments of the era.

This is to take out the hurricane over Arizona that is currently in the best 
track.  MWL says that its remnants made it into Arizona, not a full hurricane.  
It is highly unlikely that it kept hurricane strength over the southwestern US. 
 Recommend weakening to TS over Arizona and show a typical dissipation thereafter.

Change is based on a ship report of 939 mb.  In addition, wind report of 110 kt 
matches approximate pressure/wind relationship that confirms the ship.  
Recommend Category 3 for hurricane landfall based on ship and land station (all MWL).

Also add landfall x=1 because system crossed the coast as a TS


For whatever reason, Simone 1968 is not in the best track, despite its existence 
chronicled in many publications.

The track of the system is based off the 1968 Navy Annual Tropical Cyclone Report,
 Annex A.  No intensities are noted in the Navy report.  However the 1968 MWR 
article says that winds of 40 to 45 kt were reported as the ship was (apparently) 
moving through the center.  MWL mentions the same short-lived storm, though it has 
the ship reporting 40-50 kt maximum winds and a pressure of 1005.4 mb in the center.  
45 kt is chosen as the maximum intensity, which better fits the relatively high 
pressure of 1005 mb reported than 50 kt.  45 kt is also a useful value because of 
the uncertainty involved since it is the value of generic tropical storms in the 
EPAC database.

Change is based on a reconnaissance report of 110 kt (measured) by an Air Force 
plane.  The level is unknown so used a conservative 80% reduction to reach a 
landfall intensity of 90 kt.  MWL states the hurricane rapidly intensified right 
before landfall.

This adjustment is to move the track inland based on MWL and extrapolation.  For 
the 1981-1987 period, many storms simply stopped near or offshore because Redwood
 City stopped writing advisories on them before moving inland.  Changes are 
cosmetic to show actual landfalls.
