Get more information, more quickly during an emergency by signing up for HNL Alert, the City and County of Honolulu’s mass notification system for O’ahu’s residents and and visitors. With HNL Alert, subscribers can choose the types events to be alerted about and how they wish to be notified. Subscribers can even enter one or more addresses to get targeted alerts about events impacting specific areas of concern, including home and workplaces.
The City uses HNL Alert in addition to warning systems that don’t require sign up, such as wireless alerts that sound on your mobile device, sirens, and alerts that interrupt radio and TV. While some warning systems are intended for urgent emergency situations, HNL Alert can keep you informed about developing weather conditions and other situations affecting City services that our communities rely on. HNL Alert messages can contain more details, include images and links to real-time information, and don’t disappear quickly from subscribers' devices so they have more time to read and understand the information or share it with others.
