Warning, watch or advisory?

  • Warning — the hazard is happening or about to. Act now: take shelter, leave, or stay off the roads.
  • Watch — conditions could produce it. Have a plan and keep checking.
  • Advisory — less serious, but a nuisance or a risk for some people, such as drivers or those sensitive to heat.
  • Statement — information that does not reach advisory level.

Receiving alerts on your phone: Wireless Emergency Alerts are on by default for the most serious warnings. A NOAA Weather Radio keeps working when the power and the mobile network do not.

What this page shows, and what it misses

Alerts come straight from the US National Weather Service (api.weather.gov), refreshed every five minutes. The most serious appear first. Alert text is the NWS's own; times in each headline are the issuing office's local time. Local emergency managers sometimes issue orders — evacuations, boil-water notices — that are not weather alerts and do not appear here. Severe and extreme alerts also go into our United States incident record. Method: about · credits: licences.
