Arlene

The name of the first Atlantic storm of 2011. Hurricane names rotate in a six-year cycle with the 2011 list being a repeat of the 2005 names. The World Meteorological Organization retired the names of four major hurricanes that made landfall in the United States during 2005: Dennis, Katrina, Rita and Wilma. Stan, a Category 1 storm, was also retired after causing extensive loss of life in Central America. They have been replaced by Cindy, Franklin, Irene, Katia and Sean.

2005

In one of the busiest Atlantic hurricane seasons on record, 28 named storms formed, forcing use of the alternate Greek alphabet scheme for the first time. When the National Hurricane Center's list of 21 approved names runs out for the year, hurricanes are named after Greek letters. Of the 28 named storms in 2005, 15 were hurricanes, with four storms reaching Category 5 status (Dennis, Katrina, Rita and Wilma) and three more being considered major.

Preparing for Emergencies Using Census Data

The growth in population of coastal areas illustrates the importance of emergency planning and preparedness for areas that are more susceptible to inclement weather conditions. The U.S. Census Bureau's official decennial census and population estimates, along with annually updated socioeconomic data from the American Community Survey, provide a detailed look at the nation's growing coastal population. Emergency planners and community leaders can better assess the needs of coastal populations using census data.

Hurricane Andrew and Homestead, Fla.

1992

Hurricane Andrew forms in the Atlantic Ocean and makes landfall in Florida on Aug. 24, destroying a large swath of South Florida, most notably the city of Homestead. Andrew later made landfall on the central Louisiana coast on Aug. 26 as a Category 3 hurricane. Hurricane Andrew was the second costliest tropical cyclone in U.S. history and killed 23 in the U.S.
