Red Flag Warning

A Red Flag Warning is issued for weather events which may result in extreme fire behavior that will occur within 24 hours. A Fire Weather Watch is issued when weather conditions could exist in the next 12-72 hours. A Red Flag Warning is the highest alert. During these times extreme caution is urged by all residents, because a simple spark can cause a major wildfire. A Fire Weather Watch is one level below a warning, but fire danger is still high

Radios and public broadcasting are part of the emergency alerting system and are the primary methods when cellular and landlines are down. The PBS WARN site shows WEAs for all areas which may be useful if someone doesn’t receive an alert OR if they are interested in viewing alerts in a different geographical area.
