1949 Florida hurricane
Encyclopedia
The 1949 Florida hurricane was the second recorded storm and the strongest and most intense tropical cyclone
Tropical cyclone
A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. Tropical cyclones strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor...

The Atlantic hurricane season is the period in a year when hurricanes usually form in the Atlantic Ocean. Tropical cyclones in the North Atlantic are called hurricanes, tropical storms, or tropical depressions. In addition, there have been several storms over the years that have not been fully...

Meteorological history

On August 23, a moderate tropical storm developed 200 miles (323 km) east of Sint Maarten. Operationally, the system was treated as an easterly wave until it moved through the Bahamas. It is believed that the system originated near the Cape Verde

, and then strengthened to a minimal hurricane with 75 mph (120 km/h) winds on August 25. Subsequently, it strengthened rapidly, and the cyclone was noted as "well developed" when it passed near Nassau with 115 mph (185 km/h) winds on the morning of August 26. At the time, it was the equivalent of a Category 3 hurricane on the Saffir-Simpson Hurricane Scale. The storm strengthened further over the Gulf Stream, and it moved ashore over the city of West Palm Beach as a strong Category 4 hurricane around 7:20 p.m. EDT. The city's airport reported calm conditions from 7:20–7:40 p.m., and the minimum central pressure of 954 mbar (28.18 inHg) was measured at the site. Peak gusts were recorded at 125 mph (205 km/h) before the anemometer blew away. A maximum sustained wind of 153 mph (246 km/h) was reported from the Jupiter Inlet Light
Jupiter Inlet Light

 lists the cyclone as a strong Category 4 hurricane at landfall. The wind reading is the basis for the Category 4 designation in the Atlantic hurricane database, although a reduction from the anemometer's elevated location lends credence to the concept of a weaker system. Originally, the system was designated as a Category 3 hurricane in the state of Florida, based on the minimum central pressure reading of 954 mbar (28.18 inHg); this pressure corresponds to the original classification of a Category 3 hurricane on the Saffir-Simpson Hurricane Scale. However, modern analysis applies Saffir-Simpson rankings based on maximum sustained wind speeds. The 1949 Florida hurricane will be eventually reanalyzed by the Atlantic hurricane reanalysis project

, which may find a weaker hurricane in Florida. The central pressure of 954 mbar (28.18 inHg) is unusually high for a strong Category 4 hurricane; the reanalysis project has discovered that hurricanes erroneously featured stronger winds than the typical pressure/wind relationship in the 1940s–1960s, unlike subsequent hurricanes in the 1970s–1980s. The evidence suggests wind speeds may have been overestimated for hurricanes in the 1940s–1960s.

Preparations

On August 25, the northern Bahamas were advised to initiate hurricane precautions, and a hurricane warning was issued for the islands. South Floridians were encouraged to closely monitor the progress of the storm. On August 26, hurricane warnings were released from Miami to Vero Beach; officials decided to cancel proposed evacuations of the Lake Okeechobee region, as the presence of the Herbert Hoover Dike was expected to prevent flooding.
