List of Storm Prediction Center extremely critical days

An extremely critical fire weather event is the greatest threat level issued by the NWS Storm Prediction Center (SPC) for wildfire events in the United States. On the scale from one to three, an extremely critical is a level three; thus, these outlooks are issued only when forecasters at the SPC are confident of extremely dangerous wildfire conditions on a given day, and are typically reserved for the most extreme events.
