Hurricane Ida struck the Gulf Coast on Sunday as a Category 4 hurricane bringing driving rains and flooding, and knocking out power for hundreds of thousands of people in Louisiana and Mississippi. So far, four people have been found dead in the two states. As of Monday, at least 670 people had been rescued. A new storm, Kate, reached land on Monday, before being downgraded to a tropical depression. If you live in surrounding areas that were affected, a Facebook tool can let your friends and family know you're safe.

The feature, called Safety Check, is part of the Crisis Response page Facebook developed to help people quickly stay in the know about worldwide disasters. The page can also be used to donate money to the areas affected by these events. 

If you're in a location that has experienced a hurricane or other crisis, Facebook says a notification should automatically appear when you log in to let your friends know you're safe. However, if you don't see a notification, we'll explain how to find the tool.
