Four previously unknown tropical cyclones were identified using records, including historical weather maps and ship reports, while information on the known storms was amended.

The storm devastated southwestern Louisiana in early August, especially Cameron Parish, leaving 34 fatalities and approximately $5 million (1918 USD) in damage.

After reaching the Gulf of Mexico, the storm strengthened into a Category 1 hurricane on the modern day Saffir–Simpson scale at 12:00 UTC on August 5.

[5] In Lake Charles, debris from destroyed homes and downed electrical wires left nearly all streets impassable.

On August 25, the hurricane peaked with maximum sustained winds of 105 mph (165 km/h) and a minimum barometric pressure of 968 mbar (28.6 inHg).

Early the following day, the storm briefly re-emerged into the Caribbean before making landfall near Monkey River Town, Belize.

[3] A low-pressure area developed into a tropical storm by 06:00 UTC on August 23, while located about 240 mi (390 km) east-northeast of the northern Bahamas.

Around 18:00 UTC on August 24, the cyclone intensified into Category 1 hurricane, peaking with maximum sustained winds of 75 mph (120 km/h).

[3] While moving across coastal North Carolina, the cyclone weakened to a tropical storm early on August 25, several hours before re-emerging into the Atlantic.

[3][4] Abnormally high tides and strong winds left some damage to crops, fencing, and buildings,[3] especially at Atlantic, Ocracoke, and Harkers Island.

[3] A low-pressure area of non-tropical origins developed into a tropical storm about 815 mi (1,310 km) east-northeast of Bermuda on August 31.

[4] Early on September 4, the system peaked with maximum sustained winds of 70 mph (110 km/h) and a minimum barometric pressure of 992 mbar (29.3 inHg).

[4] The cyclone moved west-northwestward and reached hurricane status early on September 3, based on a ship observation of 81 mph (130 km/h) winds.

[4] While passing west of Bermuda early the following day, winds of at least 60 mph (100 km/h) bring down trees and shatter windows, while many boats were swamped or blown aground.

[8][9] Early on September 5, the hurricane peaked with maximum sustained winds of 110 mph (175 km/h) and a minimum barometric pressure 972 mbar (28.7 inHg).

[3] Upon reaching the northwestern Caribbean on September 14, the storm weakened to a tropical depression, before dissipating about 170 mi (270 km) west of the Cayman Islands around 12:00 UTC.

While tracking northwestward, the depression experienced little change in intensity and made landfall in Louisiana three days after formation.
