When danger develops nearby, reliable information can help you decide whether to shelter, evacuate, avoid roads, or check on someone vulnerable. The safest approach is to use several official sources and know how to verify an alert before acting on rumors or forwarded messages.
Start with your local emergency alert system
Most counties, cities, and towns operate an opt-in emergency notification service. These systems may send text messages, phone calls, emails, or app notifications about evacuation orders, severe weather, missing people, hazardous materials, road closures, and other local threats.
To find yours:
- Search for your official county, parish, borough, or city website. Use a search phrase such as
your county emergency alertsoryour city emergency notification system. - Check that the website address belongs to a government organization. Common endings include
.gov, although some official local agencies use other domains. - Look for links labeled “Emergency Alerts,” “Emergency Notifications,” “Sign Up for Alerts,” “CodeRED,” “Everbridge,” “Smart911,” “Notify Me,” or similar wording.
- Register more than one contact method if available. Add your mobile number, email address, home phone, and the address or locations you want monitored.
- Read the location settings carefully. Some services send alerts based on your registered address, while others use your current phone location or selected geographic areas.
Do not assume that registering with one nearby city automatically registers you with the county, state, or neighboring communities. If you live near a boundary, work in another jurisdiction, or regularly care for relatives elsewhere, sign up for each area’s official system.
Use government websites and social media carefully
During an emergency, official websites may publish the most complete instructions, including maps, shelter locations, evacuation zones, road restrictions, and updates to earlier messages. Bookmark the websites for your local emergency management agency, sheriff or police department, fire department, public health department, and state emergency management office before an emergency occurs.
Official agencies may also post on platforms such as Facebook, X, Instagram, or other social networks. Social media can be useful for quick updates, but it should not be your only source because accounts can be impersonated, platforms can delay posts, and internet access may fail.
Before trusting an account, verify it from the agency’s official website. Follow the link from the government website rather than relying only on an account name, profile picture, or a shared post. Watch for small spelling differences in usernames, unusual payment requests, shortened links, or messages asking for personal information.
If an official page is overloaded, try the agency’s alternate channels. A county emergency management page may repeat information from the sheriff, fire department, transportation department, or state emergency office. When several verified agencies provide the same instruction, confidence in the information is stronger.
Check wireless emergency alerts on your phone
Wireless Emergency Alerts, often called WEAs, are short government messages delivered through participating cellular networks. They can include imminent threat alerts, public safety messages, AMBER Alerts, and national alerts. They are generally targeted to a geographic area, so you may receive one while traveling or miss one if your phone is outside the affected area.
On most iPhones, open Settings, choose Notifications, scroll to the bottom, and review the Government Alerts section. Make sure the alert categories you want are enabled. The exact options can vary by country, carrier, iOS version, and region.
On many Android phones, open Settings and search for Emergency alerts, Wireless emergency alerts, or Government alerts. The setting may be under Notifications, Safety and emergency, or Connections. Review the categories and allow emergency notifications, sound, vibration, and repeated reminders if those options are available.
Menu names differ between manufacturers and operating-system versions. If you cannot find the setting, use your phone’s Settings search tool, consult the manufacturer’s support page, or ask your carrier for the correct path.
Do not disable all emergency alerts because a category is inconvenient. If your phone offers separate options, adjust nonessential categories while keeping imminent-threat alerts enabled. Also check that the phone is not in a mode that silences emergency notifications, such as a special Focus, Do Not Disturb, or battery-saving configuration.
Keep a weather and broadcast backup
Internet-based alerts are valuable, but they depend on working power, cellular service, data networks, or Wi-Fi. A battery-powered or hand-crank NOAA Weather Radio with Specific Area Message Encoding can provide alerts when internet service is unavailable. Program it for your county or nearby counties and keep spare batteries available.
Local television and radio stations often broadcast emergency information, evacuation instructions, shelter notices, and weather warnings. A battery-powered AM/FM radio gives you another way to receive updates during a power outage. Some communities also use outdoor sirens, public-address announcements, highway signs, and door-to-door notifications.
These systems have different purposes. A siren may tell you to seek information, but it may not explain the hazard or identify the affected streets. If you hear a siren, turn on a local broadcast, check an official agency source when possible, and follow instructions from emergency responders.
| Source | Best use | Important limitation |
|---|---|---|
| County or city alert signup | Local warnings and instructions | Usually requires registration |
| Wireless Emergency Alerts | Fast, location-based phone messages | May not include detailed instructions |
| Official emergency management website | Maps, updates, and full guidance | Can be slow or unavailable during heavy traffic |
| NOAA Weather Radio | Weather warnings during outages | Requires proper setup and batteries |
| Local radio and television | Broad public updates | May not cover every neighborhood |
| Verified agency social media | Rapid status updates and links | Accounts and platforms can be impersonated or delayed |
Verify an alert before sharing it
A message can look urgent and still be false, outdated, or taken out of context. Before forwarding an alert, compare it with at least one official source. Search the name of the agency and the main phrase from the message, then open the agency’s website directly rather than clicking a suspicious link.
Check four details:
- Who issued it? Identify the agency, department, or public safety authority.
- What area is affected? Confirm the alert applies to your neighborhood, route, workplace, or family member.
- When was it issued or updated? An old evacuation notice may have been lifted, expanded, or replaced.
- What action is required? Distinguish between a watch, advisory, warning, shelter-in-place order, and evacuation order.
Screenshots and forwarded text may omit important information. Look for the original announcement, official map, phone number, or incident page. If officials say information is unconfirmed, do not present speculation as fact.
An alert does not become false merely because you cannot find it immediately online. Agencies may first send a targeted phone alert, publish through dispatch channels, or issue information through local broadcasters. Continue checking multiple official sources while taking reasonable protective action.
Understand the difference between warnings and orders
Emergency terminology varies by location, but the wording usually signals urgency. A watch means conditions are possible and you should prepare. An advisory generally describes a hazard that may cause inconvenience or require caution. A warning means a threat is occurring or imminent in the specified area.
An evacuation warning may mean residents should prepare to leave, gather medications, secure pets, and monitor instructions. An evacuation order means authorities are directing people to leave or move to a safer location. A shelter-in-place instruction means you should remain indoors or in another designated safe place and follow specific protective steps.
Read the entire official message. It may specify which roads to use, which routes are closed, where not to go, whether shelters accept pets, or when the order will be reviewed. Never enter an evacuated area simply to inspect property unless authorities explicitly allow it.
Troubleshoot missing or delayed alerts
If you are not receiving messages, work through the likely causes:
- Confirm that your phone number, email address, and physical address are correctly registered with the local system.
- Check the alert account’s spam, junk, blocked-message, and email-filter folders.
- Make sure cellular service, Wi-Fi, notifications, location permissions, and emergency-alert settings are enabled as appropriate.
- Restart the phone and install pending operating-system updates when it is safe to do so.
- Check whether your carrier supports the relevant alert service and whether your phone is compatible.
- Look at the agency’s website or call its published non-emergency number for registration help.
- Add a second source, such as weather radio or local broadcast radio, rather than relying on one delivery method.
Alerts may be delayed by network congestion, power failures, damaged infrastructure, poor reception, roaming, phone settings, or the geographic limits of the system. Some local services do not send a message for every incident, and some warnings are targeted only to a small area. No notification system guarantees delivery.
If you receive a message after conditions have changed, find the latest update from the issuing agency. Do not assume that silence means the danger has ended.
Prepare your household to use alerts
Discuss alert terms and actions before an emergency. Decide who checks official information, who contacts relatives, where everyone meets, and how you will communicate if cellular service is intermittent. Keep a written list of important phone numbers, addresses, medications, and emergency contacts.
Make sure children, older adults, visitors, and people with disabilities know how alerts will reach them. Arrange accessible formats, language support, visual or vibrating notifications, and backup assistance where needed. Include pets and livestock in evacuation planning.
Save the official websites and phone numbers offline or on paper. Keep phones charged, maintain a portable power bank, and store spare batteries for radios. If you lose internet access, continue monitoring broadcast radio, weather radio, emergency responders, and public announcements.
The most dependable approach is layered: enroll in your local notification system, keep wireless emergency alerts enabled, bookmark verified government sources, maintain a battery-powered backup, and verify the latest instruction before sharing information. When an official alert tells you to evacuate, shelter, avoid an area, or seek assistance, act promptly and use the designated official channels for updates.
