This map provides a number of layers from external fire agencies and organizations that provide consistently updated map layers regarding the location and status of active and past wildfires managed by CalFire as well as federal agencies. In addition, a NOAA weather warnings layer is included to get perspective on weather conditions that may affect the behavior of active fires. And, there is also a 2013 wildland fire potential map included in the table of contents. Please turn the layers on and off and explore the various information available in the map. This list includes all of the data sources for the map: Wildfire_Activity - Active perimeter:The Geospatial Multi-Agency Coordination Group (GeoMAC) is an internet-based mapping tool originally designed for fire managers to access online maps of current wildland fire locations and perimeters in the continental United States and Alaska. Perimeters are submitted to GeoMAC by the incident commands via FTP and web sites for downloading. This file contains all wildland fire perimeters that were submitted to GeoMAC by the incidents for the current year. The projection is geographic and the datum is NAD83. Last updated February 27, 2013, SPW. For more metadata see here CalFireData - Perimeters:Data originates from CalFire; however, metadata is not available. http://services.arcgis.com/QJfoC7c7Z2icolha/arcgis/rest/services/CalFireData/FeatureServer/1WildlandFire - Fire Location:Wildlandfire.com(www.wildlandfire.com) invites you to view and interact with a continuously updated map of current U.S. wildfire locations, fire potential areas, meteorological observations and radar imagery. These real-time layers provide insight into where a fire is located, its intensity and the localized weather patterns. Information from wildlandfire.com is professionally sourced fire intel from the boots on the ground, eyes in the sky, and ears on the radio. Chances are that information will come here first before anywhere else.

As the user interacts with the map more information becomes available. Other available tools such as measuring distance or getting a view of the terrain are available to help in assessing fire danger. We encourage you to turn on and off layers that suit your viewing preferences. The Weather Observation (Radar) and Fire Potential layers are initially turned off. Please find an area and view them as you interact with the map. The US Wildfire Locations layer displays large active fire incidents entered into the National Interagency Fire Center (NIFC) database by local emergency response groups. This layer is generated and maintained as part of the Geospatial Multi-Agency Coordination Group (GeoMAC) application, and also accessed by Natural Hazards Support System (NHSS).

Wildland Fire Potential layer was provided by the USFS and indicates zones of high, medium and low fire potential. Potential Fire

The Active Fire Perimeters layer is a product of Geospatial Multi-Agency Coordination (GeoMAC). Near real-time information for fire perimeter data is updated daily from incident sources, GPS data, infrared (IR) imagery such as fixed wing and satellite platforms.

The Federal Emergency Management Agency (FEMA) layer is created by FEMA and provides information regarding fire relief shelters locations, current status (open or closed) and number of occupancy. This near real-time layer is updated daily from FEMA Shelters.

The Moderate Resolution Spectroradiometer (MODIS thermal) layer is created from the MODIS satellite detection system and indicates hot spots that could be future fire locations identified in the last 24 hour period. Data source is the EOSDIS website hosted by NASA.

The Current Wind Conditions layer is created from hourly METAR/TAF data provided from NOAA. This layer uses arrow vectors and wind speeds to provide real-time wind flow dynamics.

Radar (Weather Observation) and weather (Red Flag Warnings) are both continuous real-time layers provided by NOAA. The weather observations layer provides high temperatures, surface pressure and wind barbs along with radar return. The weather warning layer provides an array of warnings that are available with pop-up windows. Weather_Warnings_Watches_Advisories_Statements - NOAA Weather Warnings, Watches, Advisories, and Statements:FROM NOAATitle: weather warnings, watches, advisories, and statements Author: The Yeti Team Comments: Weather Watches, Warnings, Advisories, and Statements are products of the National Weather Service (NWS).We automatically check these products for updates every 5 minutes from the NWS Public Alerts. The NWS XML Feed is parsed using the Aggregated Live Feeds methodology to take the returned information and serve the data through ArcGIS Server as a map service.

The GeoMAC web site allows users in remote locations to manipulate map information displays, zoom in and out to display fire information at various scales and detail, and print hard copy maps for use in fire information and media briefings, dispatch offices and coordination centers. The fire maps also have relational databases in which the user can display information on individual fires such as name of the fire, current acreage and other fire status information.See the Help page for more specific information.SNC - Sierra Nevada Conservancy:The Sierra Nevada Conservancy (SNC) is a California state agency created by bi-partisan legislation (AB 2600) and signed into law in 2004. The SNC was created with the understanding that the environmental, economic and social well-being of the Sierra Nevada and its communities are closely linked and that the Region and the State of California would benefit from an organization providing a strategic direction. The SNC Region, made up of all or part of 22 counties covering over 25 million acres, is one of the most significant natural and biologically diverse regions in the world. The Sierra Nevada constitutes about 25 percent of California’s land area and is the state’s principal watershed, supplying more than 60 percent of the developed water supply to residents, agriculture, and other businesses/industries across the state.Additional CalFire Layers: California Fire Perimeters - fire history:California Fire Perimeters Grouped By Year:CalFire KML Feed:CAL FIRE, USDA Forest Service Region 5, BLM, NPS, Contract Counties and other agencies jointly maintain a comprehensive fire perimeter GIS layer for public and private lands throughout the state. The data covers fires back to 1878. For the National Park Service, Bureau of Land Management, and US Forest Service, fires of 10 acres and greater are reported. For CAL FIRE, timber fires greater than 10 acres, brush fires fires greater than 50 acres, grass fires greater than 300 acres, and fires that destroy three or more residential dwellings or commercial structures are reported. Copyright Text: CAL FIRE recognizes the various federal, state, and local agencies that have contributed to this dataset, including USDA Forest Service Region 5, BLM, National Park Service, and numerous local agencies.WLFP_2013-Wildland Fire Potential 2013:For more information and access to download the GIS data, please see the Fire, Fuel, and Smoke Science Program website. The wildland fire potential (WFP) map is a raster geospatial product produced by the USDA Forest Service, Fire Modeling Institute that is intended to be used in analyses of wildfire risk or hazardous fuels prioritization at large landscapes (100s of square miles) up through regional or national scales. The specific objective of the 2012 WFP map is to depict the relative potential for wildfire that would be difficult for suppression resources to contain, based on past fire occurrence, 2008 fuels data from LANDFIRE, and 2012 estimates of wildfire likelihood and intensity generated for the Fire Program Analysis system (FPA) using the Large Fire Simulator (FSim). Areas with higher WFP values, therefore, represent fuels with a higher probability of experiencing high-intensity fire with torching, crowning, and other forms of extreme fire behavior under conducive weather conditions. On its own, WFP does not provide an explicit map of wildfire threat or risk, because no information on the effects of wildfire on specific values such as habitats, structures, or infrastructure is incorporated in its development. It is important to note that the WFP is also not a forecast or wildfire outlook for any particular season, as it does not include any information on current or forecasted weather or fuel moisture conditions.
