Agencies use this same data to help identify fires and their hot spots. The hot spots are an approximation and do not include all areas affected by fire, nor do they indicate with certainty an area was affected.

Hot spots are locations identified by satellite analysts from the National Oceanic and Atmospheric Administration (NOAA). But because of the distance of the satellites, the nature of the measurements and obfuscation by smoke, the resolution is coarse and not 100 percent accurate. Agencies use this data to help identify fires and their hot spots. They are an approximation and do not include all areas affected by fire, nor do they indicate with certainty an area was affected. The perimeters are intended to provide an idea of the scope and extent of the fires with the most current data possible. Perimeters are not available for every incident.įire perimeters for incidents before Jare based on infrared and thermal imaging from NASA's MODIS and VIIRS-I products. Perimeters do not include prescribed or incident complex fires. This map displays all current wildfire fire perimeters available through NIFC that have not been 100% contained. Fire Perimetersįire perimeters are based on geographic data from the National Interagency Fire Center, updated once an hour. Butte/Tehama/Glenn Lightning Complex (Butte Zone)įires are labeled when they are larger than 500 acres, cause damage to property, or when people are injured or killed as a result of the fire.
