How to get warned in Hawaii
- Keep Wireless Emergency Alerts on. They reach every compatible phone in the affected area, for extreme weather, evacuations and AMBER alerts. No sign-up is needed.
- Sign up for your county or city alerts. Most counties in Hawaii run their own opt-in text and email system, which sends more local messages than WEA (road closures, boil-water notices, shelter openings). Find yours through your county emergency management office or the state agency.
- Get a NOAA Weather Radio. It sounds an alarm for warnings in your county even at night and during power or cell outages. Pick a model with SAME coding so it only alerts for your area.
- Know the difference: a watch means conditions are right for a hazard, so get ready; a warning means it is happening or about to, so act now.
