Striking Florida on June 6, the storm brought localized flooding to portions of Cuba and the Southeastern United States, leaving about $1 million in damage.

[nb 1] Dora lashed much of North Florida and southeastern Georgia with hurricane-force winds, leaving five fatalities and around $280 million in damage.

The strongest storm of the season, Cleo, peaked with maximum sustained winds of 150 mph (240 km/h) and a minimum barometric pressure of 938 mbar (27.7 inHg).

[7] A disturbance that moved out of the Intertropical Convergence Zone (ITCZ) developed into a tropical depression to the east of British Honduras (modern day Belize) on June 2.

Some areas in North Florida experienced considerable damage from strong winds and hail associated with thunderstorm, particularly in Cross City.

Due to its association with a mid to upper-level trough through July 25, the depression may have been a subtropical cyclone, though such a classification could not be confirmed prior to when satellite imagery became routine.

[3] Based on ship data and baroclinic intensification, the storm likely peaked with maximum sustained winds of 60 mph (97 km/h) just before becoming extratropical about 205 mi (330 km) of Nantucket, Massachusetts, around 12:00 UTC on July 26.

[10]: 389 Television Infrared Observation Satellite (TIROS) indicated an area of disturbed weather with a weak surface circulation in the vicinity of Cape Verde on July 25.

The Atlantic hurricane database indicates that the depression strengthened into a tropical storm at 18:00 UTC on July 31, due to ships reports of winds reaching 46 mph (74 km/h).

[3] A weak trough developed into a tropical depression late on August 5 while located about 225 mi (360 km) south of Dauphin Island, Alabama.

[17] Advisories on Brenda were not initiated until 18:00 UTC on August 8, due to sparsity of data, making it difficult to confirm the existence of a tropical cyclone.

[3] The cyclone emerged into the Gulf of Guacanayabo, before striking Sancti Spíritus Province as a minimal hurricane early on August 26.

Now moving north-northwestward, the system reached Category 2 intensity early on August 27, hours before striking Miami Beach, Florida, with winds of 110 mph (180 km/h).

Cleo briefly re-emerged into the Atlantic off the coast of North Florida, before making another landfall on St. Simons Island, Georgia, early on August 29 with winds of 60 mph (97 km/h).

[8]: 180 [23] A tropical depression developed from a low-pressure area on August 28, shortly after moving offshore the west coast of Africa near Dakar, Senegal.

The remnants emerged into the Atlantic near Cape Hatteras, North Carolina, and continued northeastward, striking Newfoundland on September 15,[3] shortly before being absorbed by a larger extratropical cyclone.

[27] Heavy rainfall damaged many unharvested crops and inundated numerous of roads and bridges, isolated some communities for several days.

[3] By late on September 12, the storm curved northeastward and passed to the northeast of Bermuda early the next day,[3] bringing 4.05 in (103 mm) of precipitation and wind gusts up to 70 mph (110 km/h).

[8]: 183  The wave quickly developed into a tropical depression at 06:00 UTC on September 5, while located about 40 mi (64 km) west of Dakar, Senegal.

[32] Tracking westward, it developed into Tropical Storm Gladys while centered about midway between the Lesser Antilles and Cape Verde early on September 13.

By the next day, the cyclone quickly intensified, briefly peaking as a Category 4 hurricane with maximum sustained winds of 130 mph (210 km/h) around 18:00 UTC.

[33][34] In the former, high tides inundated homes and buildings with 2 ft (0.61 m) of water in two small villages on the Outer Banks and flooded a highway to Manteo.

After briefly re-emerging into the northwestern Caribbean Sea later that day, the depression strengthened into Tropical Storm Hilda at 11:00 UTC on September 29 while making landfall near Sandino, Cuba.

Isbell curved northwestward on October 16, weakening to a tropical storm just before making landfall in Atlantic Beach, North Carolina, with winds of 70 mph (110 km/h).

[46] Three deaths occurred in the state, one due to a heart attack and two from drowning in Florida Keys when their shrimp boat sank.

[8]: 177 An area of disturbed weather within the ITCZ developed into a tropical depression early on November 5, while located about 135 mi (215 km) north-northwest of Colón, Panama.

Several hours later, it weakened to a tropical depression along the north coast of Honduras early on November 8, shortly before re-emerging into the Caribbean.

In Puerto Castilla, large amounts of precipitation caused flooding and destroyed a bridge, leaving part of the population out of communication.

However, a re-examination of the satellite imagery as part of the Atlantic hurricane reanalysis project did not depict tropical depressions, while ship data was unavailable for either potential cyclone.

In addition, the names Ethel, Florence, Isbell, and Winny would be removed but not retired and replaced by Edna, Frances, Ingrid, and Wesley for the 1968 Atlantic hurricane season with no reason cited.
