"HURREVAC stands for HURRicane EVACuation program on a computer. The program was developed by Sea Island Software, Inc. beginning in 1988, in response to a need for computer based management of data produced by various federal Hurricane Evacuation Studies. These studies were produced for discrete regions of the country (usually a state, or in the case of Florida, a portion of a state). The purpose of the studies, and of HURREVAC, is to assist government emergency managers in making decisions for their states/communities when under a hurricane threat. […] HURREVAC tracks hurricanes on computer plot maps using information from the National Hurricane Center (National Weather Service, NOAA) and does its job of estimating when various evacuation decisions should be made, using data from the federal hurricane evacuation study for the area."
