Image of the Keetch-Byram Drought Index

Keetch-Byram Drought Index (KBDI) is an index used to determining forest fire potential. The drought index is based on a daily water balance, where a drought factor is balanced with precipitation and soil moisture (assumed to have a maximum storage capacity of 8-inches) and is expressed in hundredths of an inch of soil moisture depletion.

The Wildland Fire Assessment System (WFAS) is a public website hosted by the United States Forest Service – Rocky Mountain Research Station that collects and displays fire danger information for the United States.

 

The WFAS website contains a variety of fire danger information including:

  • Daily fire danger maps using National Fire Danger Rating System values from Weather Information Management System.
  • Access to historical fire danger maps and some tabular data.
  • Historical fire weather products including lightning /Haines Index information.
  • Fuel moisture /drought information.
  • Experimental fire potential products.

Learn more about WFAS and what it has to offer.
