Part of the 1933 Atlantic hurricane season

The 1933 Florida–Mexico hurricane was the first of two Atlantic hurricanes to strike the Treasure Coast region of Florida in the very active 1933 Atlantic hurricane season. It was one of two storms that year to inflict hurricane-force winds over South Texas, causing significant damage there; the other occurred in early September. The fifth tropical cyclone of the year, it formed east of the Lesser Antilles on July 24, rapidly strengthening as it moved west-northwest. As it passed over the islands, it attained hurricane status on July 26, producing heavy rains and killing at least six people. Over the next three days, it moved north of the Caribbean, paralleling the Turks and Caicos Islands and the Bahamas. The storm produced extensive damage and at least one drowning as it crossed the Bahamas. On July 29, the cyclone came under the influence of changing steering currents in the atmosphere, which forced the storm into Florida near Hobe Sound a day later. A minimal hurricane at landfall, it caused negligible wind damage as it crossed Florida, but generated heavy rains along its path, causing locally severe flooding. The storm turned west, weakened to below hurricane status, and later exited the state north of Charlotte Harbor on July 31.

Once over the eastern Gulf of Mexico, the storm shifted its course to the west-southwest and gradually recovered its intensity. The path of the storm brought it close to the mouth of the Rio Grande in early August. Few ships encountered the small storm as it regained hurricane status on August 4, just a day before striking northern Mexico with winds of 90 mph (145 km/h)—making it close to a modern-day Category 2 hurricane on the Saffir–Simpson hurricane wind scale. Striking close to the border between the United States and Mexico, the storm caused extensive damage in both countries. Winds damaged buildings and crops in Tamaulipas and the southern regions of Texas, with heavy losses to citrus production in the Rio Grande Valley. While only one person died in the United States, heavy rains led to catastrophic flooding that claimed at least 31 lives in northern Mexico; the worst-hit areas were in and near the city of Monterrey. While monetary losses in Mexico were unclear, the storm did at least $3,000,000 in damages in the United States, measured in contemporary U.S. dollars.

Historical context

The July storm was not the last to damage the Treasure Coast of Florida in 1933: a much stronger cyclone in September, with winds of 125 mph (200 km/h), extensively damaged the same area that the July storm affected. This storm overshadowed memories of the earlier hurricane, and would be remembered as among the worst on the Treasure Coast as late as the 1980s.[1][2] The occurrence of two hurricanes on the east coast of Florida in the same season is a relatively rare event in historical records, but not unprecedented: for instance, forensic research by weather historian David M. Ludlum suggests that two or more hurricanes in 1837 may have affected the region. Citing reports from William Reid in Law of Storms (1838), Ludlum noted that two hurricanes affected Central and Northeast Florida on August 1–2 and September 6, respectively, while other storms, potentially hurricanes, may have done so later in September. The September hurricane struck between St. Augustine and Jacksonville. Incidentally, the 1837 Atlantic hurricane season was apparently very active, like 1933; as in 2004, a record four hurricanes hit the state of Florida, including the infamous Racer's hurricane in October.[3]
