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. They are only issued for either Day 2 (with the event occurring the following day) or for Day 1 (on the day of the event). In contrast with high risk outlooks for severe weather outbreaks, extremely critical outlooks are commonly issued for Day 2. This is due to the fact that the conditions required for volatile wildfire spread are easier to predict well in advance than the conditions required for a major tornado outbreak or derecho. Similar to high risk outlooks, extremely critical outlooks also cannot be issued for Day 3 of the outlook period.
