Fire Weather Point Forecast Matrix
Data Mining Tool
Outreach / Education
The Fire Weather Point Forecast Matrix (PFW) and is generated routinely for the National Fire Danger Rating System (NFDRS) sites or other areas as determined by the users. This additional data will help land management agencies to ensure the safety of fire crews as well as better plan prescribed burns and other projects in a cost and resource effective manner. Also, land managers have expressed a need for better tools to predict and manage smoke dispersion. They have also requested that the NWS include an Atmospheric Dispersion Index (ADI) and Low Visibility Occurrence Risk Index (LVORI) in the PFW product. WFO Fire Weather PFW's are generated for the Remote Automated Weather Station (RAWS)/NFDRS sites using an edited version of the standard PFM formatter. This formatter produces needed fire weather parameters from the local WFO's Digital Forecast Database (DFD). PFW's can be generated for any grid point in a DFD based upon user request. The web delivery of the product for fire weather customers will include a disclaimer at the top of the page stating "This PFW product is for planning and review purposes only and is not to be substituted for an official fire weather spot forecast." The data displayed are calculated from a 5.0 by 5.0 km digital database and only approximates weather conditions in highly varying terrain. Please relay any comments you have to your local NWS office.
