Storms

Hurricane One

Category 1 hurricane (SSHS)
Duration June 16 – June 26
Intensity 90 mph (150 km/h) (1-min),  980 mbar (hPa)

A tropical storm formed in the western Caribbean before moving across the Yucatan peninsula into the southern Gulf of Mexico. The storm recurved towards the north, strengthening into a category 1 hurricane before it struck Sargent, Texas. During the night of June 21, winds increased to 68 miles per hour (109 km/h) at Corpus Christi, Texas. A barge with 18,000 gallons of oil sank in Port Aransas, Texas. A storm surge of 7.1 feet (2.2 m) was measured at Pass Cavallo. As the cyclone moved inland, it passed directly over Palacios, Texas, Wharton, Texas, and Wallis, Texas. Winds gusted to 60 miles per hour (97 km/h) at both Galveston, Texas and Houston, Texas. Heavy rains accompanied the system, with 10.10 inches (257 mm) recorded at Matagorda, Texas.[1]

Hurricane Two

Category 1 hurricane (SSHS)
Duration September 4 – September 8
Intensity 80 mph (130 km/h) (1-min),  985 mbar (hPa)

A category 1 struck Tampico, Mexico in early September after moving northwest from the Gulf of Mexico. After it dissipated on September 8, an extremely heavy rainfall event ensued across central Texas, which continued into September 11. In Williamson County, Texas, a new 18-hour rainfall record was set for the United States as 36.40 inches (925 mm) was recorded. The deluge led to one of the most destructive floods in the history of San Antonio, Texas. Water rose to 7 feet (2.1 m) deep in the city, forcing people to evacuate vertically within taller buildings. The most significant river floods occurred on the Little and San Gabriel rivers, where 159 people perished. Combined with the death toll from elsewhere across the region, 215 people died due to this storm and damages were estimated at $19 million (1921 USD).[1]

Hurricane Three

Category 3 hurricane (SSHS)
Duration September 6 – September 17

Another notable system was a tropical storm that made a transatlantic journey from off the coast of South Carolina to just southwest of the Azores. It was later determined that it was extratropical for most of the journey.

Hurricane Six

Category 4 hurricane (SSHS)
Duration October 20 – October 30
Intensity 140 mph (220 km/h) (1-min),  941 mbar (hPa)
Main article: 1921 Tampa Bay hurricane

The most notable storm of the season, was the Tampa Bay Hurricane of 1921. It developed in the southwestern Caribbean Sea on October 20. It tracked north-northwestward, steadily strengthening into a hurricane on October 22. The storm turned more north-northeastward, and upon reaching the Gulf of Mexico on October 24 it rapidly intensified to a 140 mph Category 4. It weakened as it continued to the northeast, making landfall north of Clearwater on October 25 as a Category 3 hurricane. It crossed Florida, turned eastward across the Atlantic, and became extratropical on October 28 southwest of Bermuda. Its small and quick nature, as well as well-executed warnings, only caused $3 million in damage (1921 USD), with 6 casualties.

Tropical Storm Seven

Tropical storm (SSHS)
Duration November 19 – November 25
Intensity 60 mph (95 km/h) (1-min),  1007 mbar (hPa)
