1858/01: No major changes from Partagas and Diaz's (1995a) analysis. No
track available, only one point. Storm is determined to have reached
hurricane status based upon observations from ship "L. H. Sampson".

1858/02: No major changes from Partagas and Diaz's (1995a) analysis. No
track available, only one point. Storm is determined to have reached
hurricane status based upon observations from ship "Shelter".

1858/03: Only major change to Partagas and Diaz's (1995a) analysis was to
extend the track 12 hr into Canada to account for observations in Maine.
Utilized the northern wind-pressure relationship of hurricanes for winds at
landfall. A peripheral pressure reading of 978 mb (around 17 UTC on the
16th) suggests winds of at least 75 kt - 80 kt chosen for the best
track. Central pressure observation of 979 mb gives 74 kt, for the second
landfall in Connecticut/Rhode Island - 70 kt is utilized for the second
landfall. Both of these pressure measurements support hurricane status for
this storm. Also used the Kaplan and DeMaria's (1995) inland decay model
for winds over New England. Ludlum (1963) referred to this storm as the
"New England Tropical Storm of 1858".

As the first Kaplan and DeMaria inland decay model was utilized for this
hurricane, it was appropriate to review the results with the inland
decay model explicitly designed for New England landfalling tropical
cyclones (Kaplan and DeMaria 2001). This model does decay systems faster
and suggests a downward revision to the winds at 00 and 06Z on the 17th,
which is reflected in the revised HURDAT.
Additional information on this hurricane was also obtained by Boose et al.
(2001). They analyzed this hurricane as a Category 2 at U.S. landfall based
upon a Fujita-style analysis of hurricane wind-caused destruction, but had a
slight high bias in the reconstructed versus actual damage in their damage-
based empirical wind modeling work. Thus landfall as a high end Category 1
hurricane (80 kt) in New York is reasonable to retain. Boose et al. (2001)
also estimated a RMW of 45 nmi at landfall.

1858/04: Combined Partagas and Diaz's (1995a) analysis of storms #4 and #5
into one continuous track. No other changes from Partagas and Diaz's (1995a)
analysis. The storm is determined to have reached hurricane status based
upon observations from the ships "Phantom", "Hudson" and "City of
Washington".
********************************************************************************
1858/05: Storm was originally #6 in 1858 in Partagas and Diaz's (1995a)
analysis. No major changes from Partagas and Diaz's (1995a) analysis. Storm
is determined to have reached hurricane status from observations from ship
"Priscilla".

Track adjusted slightly to allow for a more realistic translational velocity.

1858/06: Storm was originally #7 in 1858 in Partagas and Diaz's (1995a)
analysis. No major changes from Partagas and Diaz's (1995a) analysis. Storm
is determined to have reached hurricane status from destruction in Bermuda
and several ship reports.

1858 - Additional Notes:
1. The tropical storm listed as #5 in 1858 in Partagas and Diaz (1995a) was
not included into the HURDAT because we determined that this storm and
storm 1858/04 were likely the same system. Thus information on this
storm is now carried in its entirety as 1858/04, while Partagas and Diaz's
storm #5 in 1858 is removed.
