Stay Informed
When it comes to disasters, it's important to be prepared, know your zone, and get timely, accurate information. Emergency Management regularly posts preparedness information, hazard alerts, and suggested protective measures to Facebook, Nextdoor, and X. During an emergency or disaster you can trust the information you find on these official accounts. Be sure to have multiple ways to get alerts and warnings from the EOC's Joint Information Center, even during power outages. ​
-
Keep your phone, charger, radio, spare batteries, solar and car charger adapters in an easily accessible place. Make sure back-up power packs are charged and consider placing these items in a waterproof bag or container.
-
Create a list of emergency phone numbers. Include insurance company and power company, as well as your friends and family. Program these numbers into your phone and consider store at least one contact in your phone as "ICE" - In Case of Emergency.
Keep a hard copy of the list just in case your phone dies. -
Download a weather-related or local news media app to your smartphone, like this one from FEMA. These can help you keep track of approaching storms, changing conditions, and evacuation notices. AlertNassau has a mobile app option, too.
AlertNassau is part of Florida's Statewide Mass Notification System, a tool that helps public safety officials rapidly warn the population about imminent hazards in a specific area (i.e. severe weather, police activity, wildfire) via phone, text message, email, social media, and smartphone applications.
Residents who want to receive these notifications must “Opt-In” -
-
Create an account (with your own username and password) through AlertNassau
-
Provide one or more addresses in Nassau County (without a complete address, you will not receive any messages)
-
Enter details for you desired contact modes (i.e. text, e-mail, or voice call).
-
Check the "Smart Weather Alerts" you want from the National Weather Service - these NWS alerts are specific to the address(es) you enter in your AlertNassau account.
Information provided in your AlertNassau account can be updated anytime.
To opt-in only for short countywide text notices (burn bans, evacuation shelter openings, etc.) from Nassau EM via "Nixle" text the keyword OneNassau to the short phone number 888777. There is an option to use your ZIP code to get community area-specific messages like boil water notices and rabies alerts. Nixle messages are not based on a specific address and Smart Weather Alerts are not available through this system. ​
Nassau County Emergency Management uses Facebook, Nextdoor, and X platforms to engage the public and promote our mission to help the whole community before, during, and after disasters. Residents can trust that messages shared from the @NassauEM social media accounts contain the best available information at the time they are posted.
The Nation's Integrated Public Alert & Warning System (IPAWS) - WEA, EAS, and NOAA Weather Radio
IPAWS is used by authorized public safety officials to push critical information to the public in a specific area. They are used in life-safety situations when it is important to reach everyone immediately. There are three IPAWS systems that can be utilized:
-
The Wireless Emergency Alert (WEA) system transmits text to all mobile phones within range of specified cell towers.
-
The Emergency Alert System (EAS) broadcasts messages through specified radio and television stations.
-
The National Oceanic and Atmospheric Administration's (NOAA) Weather Radio system sends messages to all weather radios programmed with the Specific Area Message Encoding (SAME) code for the targeted area.
