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...

Meteorological history

Frederic originated as a tropical wave which moved off the west coast of Africa late on August 27, 1979, and became a tropical depression at 0600 (GMT) on August 29. Moving westward with a steady forward speed of 18 knots, it strengthened into Tropical Storm Frederic at 1200 (GMT) on August 30 and was further upgraded to a hurricane at 0600 (GMT) on September 1, while centered approximately 650 miles (1045 km) east of Barbados

Although conditions were initially very favorable for significant intensification, Frederic began to experience the outflow of Hurricane David

 (which had greatly intensified in the same area just days before). Subsequently, Frederic began a weakening trend early on September 2, when it weakened back to tropical storm status: this weakening trend would continue for several days as the storm followed in David's wake. Frederic passed over Puerto Rico and approached the Dominican Republic

 on September 6. Further weakening caused Frederic to drop below tropical storm strength later on the 6th just north of Haiti.

Continuing westward, Frederic crossed southeastern Cuba before paralleling the island's southern coast for the next four days. During this period, Frederic eventually escaped the unfavorable conditions left behind by David and regained tropical storm strength 100 miles (160 km) east of Cuba's Isle of Pines at about 0000 (GMT) on September 9. A turn towards the northwest followed, and Frederic became a hurricane once more near 1200 (GMT) on September 10, as it moved away from the western tip of Cuba. Frederic achieved this despite its center of circulation remaining close to land, probably because of sea surface temperature

, reaching peak intensity on 1200 (GMT) on September 12: at this time, Frederic had maximum sustained winds of 135 mph (215 km/h) and a central pressure of 943 mb (HPa), making a Category 4 hurricane.

Frederic weakened slightly before it made landfall on Dauphin Island, Alabama at 0300 (GMT) on September 13. Sustained winds were estimated at 125 mph, making Frederic a strong Category 3 hurricane at the time. The central pressure at the time was 946 mb. Landfall on the mainland occurred about an hour later near the Mississippi state line.

Moving inland, Frederic turned north and northeast and was downgraded to a tropical storm near Meridian, Mississippi

Preparations

Up to 500,000 were evacuated from the U.S. Gulf Coast in anticipation of Frederic's arrival. At the time, this was the largest evacuation in Gulf Coast history. The picture is from the aftermath of the storm. People are lined up outside of an Ice House to get ice for keeping food cool.

Caribbean

Sustained winds of 25-35 kn with gusts up to 60 kn buffeted the northeastern Caribbean. In St. Barthelemy they reported a 144 km/h gust and St. Martin at least got a 70 kn gust where damages were moderate. Frederic brought heavy rains from the northern Leeward Islands and Virgin Islands, where some tornadoes were also reported; in Guadeloupe and St. Thomas, 12 inches (300 mm) of rain fell in the space of 24 hours, while 24 inches (600 mm) fell in the space of 30 hours in St. Croix. At St. Maarten, a fishing boat sank killing seven people and killing others while the total still unknown in this island.

As much as 10 inches (0.3 m) of rain falling in 12 hours was reported in the eastern part of Puerto Rico. There were also some reports of tornadoes.

Heavy rains of up to 24 inches (.6 m) in total were experienced in the Dominican Republic for several days after the center of Frederic's circulation passed, which worsened the damage caused by David just a week earlier.

Frederic had minimal impact in eastern Cuba, but damage estimates were high in western Cuba due to a strengthening Frederic bringing tropical storm-force winds and heavy rains.

 and Gulf Shores, the latter seeing 80% of its buildings completely destroyed. The causeway linking Dauphin Island to the mainland was swept away in many areas.
Wind damage was also severe, especially across southern Alabama. Hurricane-force gusts were felt as far inland as Choctaw County. Structural failure was widespread in the immediate landfall area with industrial, residential and governmental buildings as well as hospitals suffering heavy damage. Nearly 90% of the Mobile area lost electricity, and the historic City Hall experienced heavy roof damage. Many small beach houses were completely destroyed by high winds before the storm surge could add any effects.

Tree damage with broken limbs was extensive, leaving thousands of tall pine trees all tilted, leaning in the direction the wind had come.
Frederic also dumped heavy rainfall across much of the eastern United States: 8 to 12 inches (.3 m) of rain fell from Pascagoula

Aftermath

Eleven counties in Alabama, sixteen in Mississippi, and five in Florida were declared eligible for disaster aid.

In retrospect, Frederic has been credited with spurring redevelopment in Mobile and the surrounding Gulf Coast region. For example, in testimony before Congress
in 1992, Robert Sheets (then the director of the National Hurricane Center

Retirement
