Our mission
Built by someone who lives here, for neighbors
Living in Hawai‘i means living with some of the most powerful natural forces on earth, hurricanes, tsunamis, volcanic eruptions, earthquakes, flooding. When something happens, information is scattered across dozens of government sites, social media accounts, and news outlets. During the 2026 Kona Low, it took checking five different websites just to figure out if roads were open.
Pacific Watch was built to fix that. One dashboard pulling real-time data from official sources so you can see what's happening and what's coming, plus preparation tools like an energy planner, emergency checklists, tsunami zone maps, shelter locations, and more.

An emergency tool should work for you, not against you
When an emergency hits, the last thing you need is a pop-up ad blocking critical information. Pacific Watch will always be free, no ads, no cookies, no paywalls.
Running the app takes real time and money, servers, databases, and countless hours. If you find it useful, a coffee keeps the lights on. To everyone who has shared the site or emailed kind words, mahalo.
