g aria,Beulah. Allen. Aficia, They may not sound like killers, but they are. Theyare hurricanes that have caused death and costly destruction along the Texascoast. For newcomersto Texas,however, these names and the memoryof theirdevastation can have little meaning.Indeed, the ~isks to life andproperty from these storms have probably increased because many new settlersin coastalcounties have had no personalexperience with the energy lockedup in thesestorms or with theiroffspring, floods, lightning storms and tornadoes. Thispublication is designedto reducethe risks from severe coastal storms and hurricanesby describng whatthey are, how they work, the reasonswhy they can beso destructive,and the steps that individuals can take to protectthemselves, theirfamilies and their property, It includesstep-by-step instructions In both Englishand Spanish! for hurricanepreparation and evacuation plans, tracking charts,suggestions for recoveryafter a storm,and lists of additionalpublications on hurricanes and hurricane awareness.

Shoreline Krosion Another hurricane-related problem occurs when a hurricane hits a coastline. Erosion at the beach sometimes moves the shiireline several hundred feet. When a hurricane cros- ses offshore barrier islands, the pov crful currents can cut channels completely through an island. Hurricane Allen cut through South Padre island in 69 places. In 1983 Alicia eroded more than 100 feet of shoreline on Galveston Island in a single day, says Dr. Biib Benton, a TexasARM University civil engineer.On the island, and in fact on much of thc Gulf coast, shoreline erosionoccurs primarily becauseof hur- ricanesand tropical storms, hc says. The Texas coast has been mapped showing ero- sion zones and washovcr channels. The in- formation is public, but many existing home and condominium owners frequently arc not aware of these natural hazards. Meanwhile. there are many problemsin trying to evacuatehighly populatedcoastal areas. Often thcrc arc few evacuations routes, some with only two traffic lanes. Many of theseroutes are only a few fee above sea level. This means they can be flooded by rising waters hiiurs before land- fall. And with high winds, heavy rain and a hasty cvacuatiiin. accidentsare inevitable, slowing the process even morc. Hurricane Watch The National Hurricane Center in Miami is responsiblefor tracking and forecasting Atlantic hurricanes. They have three main tools for tracking the storm. Satellitestake pictures every 30 minutes, showing how the storm is miiving, in addi- ion to helping provide estimateson how When hurricane center officials feel that a ing doescome, it implies an urgent needfor strong it is, and on how much rain it might certain area is thrcatcned, a "hurricane action. produce.As a hurricanegets closer t
