Fire Season Waking Up, plus Dramatic 7-Day KDBI Change
The state forestry division has tracked 18 fires since July 15th east of U.S. Hwy 69. This isn't a large number for July, but it does indicate that the summer fire season is beginning, according to Forestry Division assistant director Pat McDowell.
Earlier this week, the Ticker touched on a significant four-day change in Keetch-Byram Drought Index (KBDI) conditions. Today, we've included two more maps, seven days apart (Jul 15 and 22), which show a dramatic increase.
The KBDI implies the state of near-surface soil moisture. On the images, hotter colors indicate higher KDBI values, which indicate more drying of the topmost layers of soil. The moisture content of these layers can have a significant impact on wildfire intensity
