The 1919 Atlantic hurricane season ran through the summer and the first half of fall in 1919. The first of the tropical storms formed on July 2, while the last system dissipated on November 15. The season was a below average season. Five tropical cyclones formed and only two became a hurricane. Three of the season's cyclones made landfall. The most damaging storm of the season was the 1919 Florida Keys hurricane, which killed hundreds along its path from the Florida Straits into southern Texas.
The most notable storm of the season, however, was the Florida Keys hurricane. The storm passed south of Key West as a Category 4. The storm passed over the main Gulf of Mexico shipping routes as a strong Category 4 before making landfall just south of Corpus Christi, Texas as a Category 3 hurricane. Damage totaled US$22 million (1919 dollars). The death toll in Texas was officially 286, but the overall death toll of at least 600 was due to ships lost at sea during the cyclone.
On September 2, a tropical depression strengthened to a tropical storm in the western Atlantic Ocean. It intensified to a hurricane, and it rapidly strengthened to a peak intensity of 100 mph (155 km/h) on September 3. A ship reported a pressure of 977 mbar (28.86 inHg) away from the center. The cyclone weakened and transitioned to an extratropical system on September 4.
