Ellis' (1988) Hurricane History of the Texas Coast (and mirrored in Roth's
(1997b) Texas Hurricane History website) includes the following description:

"June 25th, 1851:  A short but severe storm which passed over Matagorda Bay and 
 was described as the most disastrous experienced there to date. Caused
 widespread damage at Saluria on Matagorda Island where saltwater contaminated 
 the fresh water cisterns.  Wind damage at Port Lavaca was widespread and
 every wharf destroyed.  Indianola suffered damage to waterfront buildings,
 but the storm tide did not cover the spit of land at Power Horn." 

Based upon this account, a single-point hurricane is analyzed and added to the 
best track database.  It is quite possible that this hurricane was Category 2 
(or stronger) given the sparseness of the population in the region.

1851/02:  No major changes from Partagas and Diaz's (1995a) analysis (was
storm #1 in Partagas and Diaz), except to assume a date of July 5th for 
storm "before July 7th".  No track available, only one point.  Storm 
determined to be a hurricane based upon destruction that occurred in Tampico.

********************************************************************************

1851/03:  No major changes from Partagas and Diaz's (1995a) analysis (was
storm #2 in Partagas and Diaz), though storm documentation is somewhat weak.  
No track available, only one point.

********************************************************************************

1851/04:  No major changes from Partagas and Diaz's (1995a) analysis (was
storm #3 in Partagas and Diaz). Inland winds over Hispanola, Cuba and SE US 
reduced via methodology of Kaplan and DeMaria's (1995) inland decay model, 
but windspeed values over Hispanola and Cuba had an accelerated rate of 
decay due to the enhanced topography.   Storm tide value of 12' obtained from 
Ludlum (1963) and Barnes (1998) for St. Marks, Florida.  Storm determined to 
have reached major hurricane status based upon storm tide and extreme damage 
at landfall.  Ludlum also called this storm the "Great Middle Florida 
Hurricane of August 1851".  The best track provided appears to describe the 
full life cycle of this tropical cyclone (from its formation as a tropical 
storm to its peak as a major hurricane until its dissipation below tropical 
storm strength).

********************************************************************************

1851/05:  No major changes from Partagas and Diaz's (1995a) analysis (was
storm #4 in Partagas and Diaz).  Storm assumed to be stationary for 4 days.

********************************************************************************

1851/06:  No major changes from Partagas and Diaz's (1995a) analysis.
Inland winds over NE US reduced via Kaplan and DeMaria's (1995) inland decay 
model.  The best track provided appears to describe the full life cycle of 
this tropical cyclone (from its formation as a tropical storm until its 
dissipation below tropical storm strength).

1851 - Additional Notes:  
1.  The tropical storm listed as #5 in 1851 in Partagas and Diaz (1995a) was
not included into the HURDAT because of the evidence suggesting that the 
storm did not actually exist.  Partagas and Diaz had found an unsupported 
reference to it in Tannehill (1938), but no other information.
