In the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher.

Although it is not officially listed in HURDAT, Hurricane "Amanda", named after a ship run aground by the storm, developed in the Gulf of Mexico on May 24.

First documented by Edward N. Rappaport and Fernández-Partagás in 1995, the system capsized several other ships and caused damage along the coast of the Florida Panhandle.

In August, the third official storm capsized the American brig Bainbridge off Hatteras, North Carolina, drowning 80 people.

[3] A hurricane was first seen by the ship Addie Barnes on August 19 in the western Atlantic Ocean, about midway between the southeastern Bahamas and Bermuda.

It headed northwestward, causing heavy rains and damage to the Outer Banks of North Carolina, but remained offshore.

On August 23, the Minor was wrecked on the south side of St Paul Island, off the northeastern tip of Nova Scotia.

The steamship Dolphin, sailing from Key West to New York City, encountered a hurricane on the night of August 27 and for 18 hours thereafter.

[5] The brig Camilla was struck about 200 mi (320 km) from Sandy Hook in New Jersey on August 28 and forced to return to port for repairs.

Thereafter, the storm tracked rapidly north-northeastward and lost tropical characteristics near the Connecticut–Massachusetts–New York state lines early on September 19.

No specific locations are known for these shipwrecks so no complete track for this storm is known, but it was active in the western Gulf of Mexico beginning on September 18.

[5] Based on John Kaplan and Mark DeMaria's inland decay model created in 1995, it is estimated that the cyclone dissipated several hours later.

[3] Climate researcher Michael Chenoweth does not consider this system to have been a tropical cyclone, instead attributing the squally weather to a cold front and high-pressure area.

[9] Three ships reported encountering a tropical storm on September 26 in the western Atlantic, beginning with the Horace E. Bell about 320 mi (510 km) west-southwest of Bermuda.

[5] Chenoweth also proposed the removal of this storm from HURDAT due to "Insufficient supporting evidence from other neighboring data sources".

[9] A tropical storm formed offshore southeast Texas on at 00:00 UTC on September 29,[5] though the system exhibited some non-tropical characteristics.

[5] In Texas, strong winds and tree damage occurred at Sabine Pass, where the schooner Manhasett was driven ashore.

In Louisiana, heavy rainfall at the Atchafalaya Basin over the course of two and a half days forced Confederate troops to remain at Morgan's Ferry.

Early that day, Amanda observed a barometric pressure of 975 mbar (28.8 inHg), the lowest in association with the cyclone, and was analyzed by Chenoweth and Mock as a Category 2 hurricane with 105 mph (165 km/h) sustained winds.

[12] The storm weakened while moving inland, before accelerating ahead of a cold front and becoming an extratropical cyclone over Kentucky late on May 29.
