The 1931 Atlantic hurricane season included the deadliest hurricane in the history of Belize (then known as British Honduras). A total of 13 tropical storms were recorded during the season, which was the most since 1916. However, only three of them intensified into hurricanes and just one reached major hurricane intensity, which is Category 3 or higher on the modern-day Saffir–Simpson scale. Nine of the tropical cyclones were identified in real-time, while evidence of the existence of four other tropical cyclones was uncovered by the Atlantic hurricane reanalysis project in 2012 and added to the Atlantic hurricane database. Additionally, two of the tropical storms were upgraded to hurricane status as part of the reanalysis. Overall, the first four tropical cyclones left mostly minor impact on land. In early September, the fifth system caused severe flooding in Puerto Rico, leaving considerable damage to sugarcane crops and causing at least 30 deaths. Just days later, the British Honduras hurricane formed in the Caribbean Sea. The most intense tropical cyclone of the season, it peaked as a Category 4 hurricane with maximum sustained winds of 130 mph (215 km/h). Striking British Honduras at peak intensity, the hurricane caused about 2,500 deaths and about $7.5 million (1931 USD) in damage there. It remains the deadliest hurricane in the history of Belize. The next hurricane caused significant damage in Puerto Rico and resulted in at least two fatalities. The remaining six tropical cyclones left little to no impacts on land. Season summary Tropical cyclogenesis began in late June, with a system developing over the western Caribbean Sea on June 24. The storm struck Mexico's Yucatán Peninsula and Texas before dissipating on June 28. In July, a cyclone also developed over the western Caribbean and struck the Yucatan Peninsula and Louisiana. August was slightly more active, featuring two tropical systems. Four cyclones originated in the month of September, including all of the season's three hurricanes. The sixth system, also known as the British Honduras hurricane, developed over the southeastern Caribbean on September 6. It became the most intense cyclone of the season, peaking as a Category 4 hurricane on the modern day Saffir–Simpson scale with maximum sustained winds of 130 mph (215 km/h). The hurricane made landfall in Belize at peak intensity on September 10. In October, two additional cyclones formed, though both remained well under hurricane intensity. The season's final three tropical cyclones developed in
