The Keetch-Byram Drought Index (KBDI) indicates the potential for forest fires in an area. The index is a value from 0 to 800 where higher values indicate greater drought conditions and chances for fires. When the KBDI is high (600 or higher) or if there are "no burn" orders in effect in the area, ROCK launches are rescheduled or cancelled.
- KBDI = 0 - 200: Soil moisture and large class fuel moistures are high and do not contribute much to fire intensity.
- KBDI = 200 - 400: Typical of late spring, early growing season. Lower litter and duff layers are drying and beginning to contribute to fire intensity.
- KBDI = 400 - 600: Typical of late summer, early fall. Lower litter and duff layers actively contribute to fire intensity and will burn actively.
- KBDI = 600 - 800: Associated with more severe drought with increased wildfire occurrence. Intense, deep burning fires can be expected.
The Florida KBDI information is updated daily and reported on the Florida Forest Service website.
