A trio of tropical storms already has soaked the Atlantic and Gulf coastlines, and more are surely on the way. As hurricane season officially got underway on June 1, the Census Bureau and Department of Housing and Urban Development relased these "facts for features" about the people and places that populate the vulnerable coastal areas of the USA. Data from the American Community Survey gives communities a detailed look at neighborhood-level statistics for real-time emergency planning for the nation's growing coastal population. The statistics in the Emergency Preparedness section of this Facts for Features are released jointly with the U.S. Department of Housing and Urban Development.

The number of types of weather-related events — hurricanes and tropical storms, wildfires, flood outlook areas, disaster declaration areas and winter storms — that the Census Bureau's OnTheMap for Emergency Management tool tracks. OnTheMap for Emergency Management provides reports on the workforce and population for current natural hazard and emergency related events.

Emergency Preparedness

Statistics Released Jointly with the U.S. Department of Housing and Urban Development

51.5%
The percentage of U.S. homes that have a prepared emergency evacuation kit. The level of preparedness varies by metro area, with about 70 percent of households in the Miami and Tampa, Fla., metro areas having emergency supplies readily available in the event of an evacuation. The Austin (Texas), Chicago and Minneapolis metro areas had among the lowest rate of homes with an emergency preparedness kit. The rates for Austin, Chicago and Minneapolis were not significantly different from one another.

69.7%
The percentage of homes where the occupants said they would likely stay with relatives or friends during a two-week evacuation to a safe place that was at least 50 miles away. This was followed by staying at a hotel or motel (18.1 percent) or public shelter (4.1 percent).

History of Hurricane Naming Conventions

Alex
The name of the first Atlantic storm of 2016. Hurricane names rotate in a six-year cycle with the 2016 list being a repeat of the 2010 names. The names Igor and Tomas were retired from the 2010 list and were replaced with Ian and Tobias.
Source: NOAA's National Hurricane Center

78
The number of Atlantic hurricane and tropical cyclone names officially retired by the World Meteorological Organization. Although hurricane names are recycled every six years, for reasons of sensitivity, hurricanes and tropical storms that were so deadly and costly that re-use of the name would be considered inappropriate are retired.

1950
The year the Weather Bureau officially began naming hurricanes.
Source: NOAA's Atlantic Oceanography and Meteorological Laboratory

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 in which seven were major (Category 3 or higher). Four hurricanes reached Category 5 status (Emily, Katrina, Rita and Wilma).

2013
Despite preseason forecasts for an active hurricane season, that year had the fewest Atlantic hurricanes since 1982. While the year had a slightly above-average number of named storms (14), only two of these storms became hurricanes. For the first time since 1994, no hurricane reached major hurricane strength (Category 3 or higher). No hurricanes and only one tropical storm, Andrea, made landfall in the U.S., causing one fatality.
