National Weather Service Risk Layersįire risk data come from National Weather Service and are updated once every hour. The current map may contain hot spots up to 48 hours old. Hot spots should be considered points with no radius or resolution. every 30 minutes, and otherwise as time permits. NOAA's Hazard Mapping System Fire and Smoke Product (HMS) is based on locations of fires and significant smoke plumes detected by meteorological satellites. But because of the distance of the satellites, the nature of the measurements and obfuscation by smoke, the resolution is coarse and not 100% accurate.
Agencies use this same data to help identify fires and their hot spots. Start at the home and work your way out to 100 feet or to your property line, whichever is closer. The intensity of wildfire fuel management varies within the 100-foot perimeter of the home, with more intense fuels’ reduction occurring closer to your home. 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. Defensible space is the first line of defense for your home against wildfire. 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.
