The index measures a drought condition; it does not by itself announce a burn-ban decision or establish that a fire occurred. The two-point increase is the change in the county average from the previous day, not a change at every location within the county.
The next official daily summary is the point to check for movement in the average and range. Readers can use the Forest Service’s KBDI page to inspect the county reading and its scale; this reading alone does not establish what action local officials will take.
