With Hurricane Irma expected to make landfall in Florida this Saturday it’s more important than ever to be prepared, especially if you don’t have cellular service following the storm.

Also on Vigliarolo’s list is the FEMA mobile app. It displays warnings, survival tips, and shelter locations near you–all indispensable information when a hurricane is bearing down. The FEMA app’s most important feature, finding nearby shelters, does require an internet connection. You should use it before any storms hit to find out where to go in an emergency.

Lastly, Vigliarolo says the Red Cross’ suite of first aid apps are all must-haves during a disaster. General first aid, pet first aid, and a variety of natural disaster aid apps are available. You should download the ones that could pertain to your situation.
