Hurricane Alert Apps: How to Get Reliable Phone Warnings

Card No. 06·52306 · Updated · Standard formula, shown below

When a hurricane is bearing down, your phone can be the difference between getting to safety and being caught off guard. This guide shows you how to set up your phone to receive the most reliable, life-saving weather alerts, from official government warnings to local emergency notifications, and how to make sure they actually get through when the power and cell towers start failing.

What You’ll Need

  • A smartphone (iPhone or Android) with a working cellular or Wi-Fi connection
  • A charged battery or portable power bank
  • Your phone’s settings menu (for enabling Wireless Emergency Alerts)
  • Optional but recommended: a NOAA Weather Radio app or a dedicated hurricane tracker app

Step-by-Step

  1. Enable Wireless Emergency Alerts (WEA) on your phone. These are the official, government-issued alerts that appear as a loud, text-like notification on your screen. They are sent by FEMA and the National Weather Service and are the most reliable source for hurricane warnings. On an iPhone, go to Settings > Notifications and scroll to the very bottom. Make sure Government Alerts are toggled on, including Extreme Alerts, Severe Alerts, and Emergency Alerts. On Android, the path varies by manufacturer, but usually it’s Settings > Apps & Notifications > Advanced > Emergency Alerts or Settings > Safety & Emergency. Look for options like Extreme threats, Severe threats, and Amber alerts and turn them all on. These alerts are free and do not count against your text message plan.
  2. Download a reliable hurricane tracking app. While WEA is the gold standard, dedicated apps provide more detail and predictive tracking. Choose a reputable one from the official app store for your platform. Look for apps that use data from the National Hurricane Center (NHC) directly. Some popular, widely-used options include the American Red Cross app (which also provides shelter locations and safety tips) and the official FEMA app. Avoid apps that are ad-heavy or ask for excessive permissions. Read recent reviews to ensure the app is actively maintained and not prone to crashing.
  3. Set up local emergency alerts. Many counties and cities have their own alert systems for evacuation orders, shelter information, and localized flooding. These are often separate from WEA. Search online for your county’s name plus “emergency alerts” or “reverse 911.” You will typically need to register your phone number and address. Some systems use apps like Everbridge or CodeRED, while others send text messages directly. Sign up for these before a storm is imminent, as registration can take a few minutes and may be delayed during high traffic.
  4. Turn on background app refresh and disable battery saver for your alert apps. If your phone kills background processes to save battery, your weather apps might not update or deliver alerts in real time. On iPhone, go to Settings > General > Background App Refresh and ensure it’s enabled for your weather and emergency apps. On Android, go to Settings > Apps > [App Name] > Battery and select Unrestricted or Optimize (not Restricted). This ensures the app can run in the background and send you notifications even when you’re using other apps.
  5. Set up a second, independent alert method. Do not rely solely on your phone. A NOAA Weather Radio with battery backup is the most reliable backup, as it receives broadcasts directly from the National Weather Service and works even when cell towers are down. If you don’t have one, consider a portable hand-crank radio. For your phone, enable Test Emergency Alerts if available (on some Androids) to see how the alert will look and sound. Also, make sure your phone’s volume is turned up and that Do Not Disturb is turned off during the storm, or set Do Not Disturb to allow emergency alerts to break through (this is usually the default).
  6. Keep your phone charged and protect it from water. Before the storm hits, charge your phone to 100% and keep a portable power bank fully charged. Put your phone in a waterproof bag or a Ziploc bag to protect it from rain and flooding. If you lose power, conserve battery by reducing screen brightness, closing unnecessary apps, and switching to airplane mode when you don’t need to make calls (you can still receive Wi-Fi alerts if you have power for your router, but cellular is more likely to work).
  7. Know what to do when you receive an alert. When a WEA alert comes through, it will sound a special, loud tone and vibrate. Read the message carefully. If it’s a warning (not a watch), take action immediately. For a hurricane warning, that means sheltering in place or evacuating if ordered. Do not call 911 for information; use local news or the apps for updates. Remember that alerts are location-based, so if you have location services turned off, you might not receive them. Keep location services on for your emergency apps.

Common Mistakes

  • Ignoring the difference between a watch and a warning. A watch means conditions are possible; a warning means they are expected. Many people wait for a warning, which may be too late. Treat a hurricane watch as a signal to prepare, and a warning as a signal to act.
  • Turning off government alerts. Some people disable WEA because they find the test alerts annoying. This is a critical mistake. Keep them on, even if you receive occasional tests.
  • Relying solely on social media. Facebook and Twitter can be useful, but they are not official sources. Information can be outdated or inaccurate. Always cross-reference with official NWS or local emergency management posts.
  • Not signing up for local alerts. WEA covers federal and state-level alerts, but local evacuation orders and shelter openings are often only sent via county systems. Missing these can be dangerous.
  • Forgetting to charge your phone. A dead phone is useless. Even if you have a power bank, you need to charge it beforehand. Many people wait until the power goes out to realize their phone is at 20%.

Tips

  • Test your alerts before the season. Some phones allow you to send a test alert. Use this to verify your settings are correct and that you can hear the tone. If you can’t find the test option, set a reminder on your calendar to check your settings at the start of hurricane season (June 1).
  • Use multiple apps for redundancy. If one app fails to update, another might work. Just don’t let too many apps drain your battery. Two or three reliable ones is enough.
  • Know your evacuation zone. Your local emergency management website will have a map of zones. Know which zone you are in and what the evacuation routes are. This will help you respond quickly to alerts.
  • Keep a written list of emergency contacts. If your phone is lost or damaged, you’ll need a physical list of family, friends, and emergency services numbers.
  • Consider a satellite messenger. If you live in a remote area or plan to ride out the storm in a place with poor coverage, a device like a Garmin inReach can send text messages via satellite. This is an expensive option but can be a lifesaver.

Troubleshooting

  • No alerts are coming through. First, check that WEA is enabled in your phone’s settings. Then, make sure you have a cellular signal. If you’re in airplane mode, you won’t receive them. Restart your phone. If you’re in a building with poor reception, move to a window or go outside. Also, verify that your phone’s software is up to date, as older versions may have bugs.
  • Alerts are too quiet or not sounding. Check your phone’s volume settings. WEA alerts have a dedicated volume that may be separate from your media volume. On some phones, you can adjust this in the emergency alert settings. Also, check if Do Not Disturb is on; by default, emergency alerts should bypass it, but some custom Android skins may not allow that. Ensure your phone is not in silent or vibrate mode.
  • The app is not updating. Close the app and reopen it. Check your internet connection. If you’re on Wi-Fi, try switching to cellular data. Clear the app’s cache (on Android) or delete and reinstall the app (on both platforms). If the app is still not working, it may be down due to high demand; rely on WEA and local news instead.
  • You’re not receiving local alerts. Verify that you completed the registration for your county’s alert system. Check your spam folder for a confirmation email. Ensure you provided a valid phone number and that you opted in for text messages. Some systems require you to text a keyword to a short code to activate.
  • Phone is dead and you have no power. Use a car charger if you have access to a car. Many public libraries and community centers serve as charging stations during outages. A hand-crank charger is a good investment for long-term outages.

Frequently Asked Questions

Q: Are Wireless Emergency Alerts really free?
A: Yes, WEA messages are sent by the government and do not count against your text message plan. You will not be charged for receiving them.

Q: Will my phone receive alerts if I’m not in the hurricane zone?
A: It depends. WEA alerts are location-based, so you will only receive them if your phone is in the affected area. If you are traveling, you may receive alerts for the area you are currently in.

Q: Can I opt out of WEA alerts?
A: You can opt out of severe and extreme alerts on some phones, but you cannot opt out of presidential alerts, which are only used for national emergencies. It is strongly recommended that you keep all alerts enabled.

Q: What is the difference between a hurricane watch and a hurricane warning?
A: A hurricane watch means hurricane conditions (sustained winds of 74 mph or higher) are possible within 48 hours. A hurricane warning means those conditions are expected within 36 hours. A warning is more urgent and requires immediate action.

Q: Should I trust third-party weather apps over the National Weather Service?
A: No. The National Weather Service is the official source for hurricane forecasts and warnings. Third-party apps can be helpful for visualization and tracking, but they should not be your primary source for life-safety alerts.

Q: What if I have an older phone that doesn’t support WEA?
A: Most phones from the last decade support WEA. If yours does not, you can still receive alerts via weather apps and local news. Consider upgrading your phone if you live in a hurricane-prone area.
