The Two River's Chapter of the American Red Cross included Clarksville TN. The Red Cross has developed Emergency Disaster Apps to help people prepare for oncoming disasters, alerts them to warnings in their area, and helps them know what to do after a disaster strikes. The three biggest apps for the Clarksville Area are the Tornado App, Flood App, and Earthquake App.
To download an app, first go to the settings on your mobile device and turn your location services on. This helps not only you, because you are then updated on the disasters occurring around you, but the chapter is able to use the information to make sure the community is informed. Once location services are on, go to either the App Store (f Apple devices) or the Google Play Store (for Android devices) and search 'Red Cross.' Many apps will come up in the search, but you are free to download the apps you feel are most suited to your area.
