The 1920 Louisiana hurricane was a strong tropical cyclone that caused significant damage in parts of Louisiana in September 1920. The second tropical storm and hurricane of the annual hurricane season, it formed from an area of disturbed weather on September 16, 1920, northwest of Colombia. The system remained a weak tropical depression as it made landfall on Nicaragua, but later intensified to tropical storm strength as it moved across the Gulf of Honduras, prior to making a second landfall on the Yucatán Peninsula. Once in the Gulf of Mexico, the storm quickly intensified as it moved towards the north-northwest, reaching its peak intensity as a Category 2 hurricane with winds of 100 mph (160 km/h) prior to making landfall near Houma, Louisiana with no change in intensity. Afterwards, it quickly weakened over land, before dissipating on September 23 over eastern Kansas.
As it approached the United States Gulf Coast, the hurricane forced an estimated 4,500 people to evacuate off of Galveston Island, and numerous other evacuations and precautionary measures to occur. At landfall, the hurricane generated strong winds along a wide swath of the coast, uprooting trees and causing damage to homes and other infrastructure. Heavy rainfall associated with the storm peaked at 11.9 in (300 mm) in Robertsdale, Alabama. The heavy rains also washed out railroads, leading to several rail accidents. Across the Gulf Coast, damage from the storm totaled to $1.45 million,[nb 1] and one death was associated with the hurricane.
