In an island state where natural hazards like hurricanes, tsunamis, and severe weather are a constant possibility, staying informed is a critical component of public safety. The City and County of Honolulu employs a comprehensive, multi-layered strategy to alert its residents and visitors during emergencies. Understanding these systems is essential for ensuring you receive timely and accurate information when it matters most.
The foundation of Honolulu’s emergency notification strategy consists of three primary systems designed to capture the public’s immediate attention without requiring any prior sign-up.
- Wireless Emergency Alerts (WEA): These are text-like messages sent directly to WEA-capable mobile phones within a specific geographic area. Authorized by federal, state, or local agencies, these alerts are used for imminent threats to life, AMBER alerts for missing children, or national emergencies. They are automatically received and accompanied by a distinct sound and vibration.
- Emergency Alert System (EAS): This national system allows authorities to interrupt local radio, television, and cable broadcasts to deliver urgent information. It is most frequently activated by the National Weather Service for weather warnings but can also be used by local officials for evacuation orders or other critical instructions.
- Statewide Outdoor Warning Sirens: Maintained by the Hawaiʻi Emergency Management Agency (HI-EMA), these sirens are a crucial tool for broad, island-wide alerts. When you hear a steady tone, it is a signal to immediately tune into local media for detailed instructions. The sirens are tested on the first business day of every month at 11:45 a.m.
While these systems are designed for urgent, life-threatening situations, the Department of Emergency Management (DEM) offers a more detailed and customizable notification service called HNL Alert. This free, opt-in service provides residents with more in-depth information about developing situations, from weather conditions to impacts on city services. Unlike the brief WEA messages, HNL Alerts can include images, maps, and links to real-time data.
There are two ways to subscribe:
- Customized Alerts: By creating an account at hnlalert.gov, users can choose to receive notifications via text message, email, or push notifications through the “Public Safety by Everbridge” mobile app. This allows for tailored alerts for specific locations like home or work.
- Urgent Alerts Only: For a quick subscription to the most critical text alerts, you can text “HNLALERT” to 888777.
In addition to these systems, the city offers the HNL Info mobile app, available on both the Apple App Store and Google Play Store. The app aims to be a one-stop source for information on traffic, weather advisories, and public safety events. However, user reviews on both platforms indicate some public frustration. Several users have reported issues with notifications not functioning correctly and have expressed disappointment with changes from a previous system, Nixle. Some recent reviews note a shift in the app’s focus, suggesting that emergency alerts are now handled through the separate HNL Alert (Everbridge) system.
For comprehensive preparedness, officials recommend having multiple ways to receive emergency information. Following official social media accounts, such as the Oʻahu Department of Emergency Management on X, and keeping a NOAA Weather Radio in your emergency kit are excellent backup measures. These tools ensure that even if one system fails or is unavailable, you can still access the life-saving information you need.
