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. Extremely critical areas are issued only several times a year when forecasters at the SPC are confident of extremely dangerous wildfire conditions on a given day. These are typically reserved for the most extreme events.

Therefore, it is likely that there were additional extremely critical days from 1998 to 2000 that were not documented.
