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. 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.^[1][2]

Progression of a well-anticipated extremely critical event across the Central Plains on March 6, 2017. This event produced wildfires that burned 1,200,000 acres of land, and killed seven people.

Notes

1. All values include fires that took place outside of the extremely critical area(s). Burned area values are listed in acres. Fatality totals only include direct fire-related deaths that occurred on the respective extremely critical days.
2. Number of acres burned for entire event which occurred over a multi-day period.
3. Approximate total number of acres burned for multiple wildfire events between June and September 2000.
4. The Red Flag Threat Index (RFTI) is a fire weather index that was developed in 2011, with values from 0-10 that rates the climatological rarity of combined relative humidity and wind combinations. Historically Critical values of 9 or 10 can only be reached when either relative humidity or wind speed exceed a ten year observational data set.
5. All 85 fatalities were caused by the Camp Fire.^[236]
6. The 102 fatalities associated with the wildfires in Hawaii on August 8, 2023 are excluded, due to the fact that only critical fire conditions were forecasted for that day.
7. There were sixteen fatalities in California from the North Complex Fire,^[270] as well as nine fatalities in Oregon and one fatality in Washington state from various other fires.^[267]
