If you have been affected by a disaster, the Red Cross "Safe and Well" website provides a way for you to register yourself as "safe and well."
Concerned family and friends can search the list of registrants to view a loved one’s First Name, Last Name, an "As of Date", and selected "safe and well" messages. More resources are available on the "Safe and Well" website.
During a disaster, communicate to your family members, letting them know of your well-being.
