Comal County’s drought index averaged 567 on Oct. 31, down 17 points from the previous day.
The Texas A&M Forest Service’s daily summary puts the county’s lowest reading at 325 and its highest at 674. That spread means the county average does not describe every location equally.

Residents considering outdoor burning need a separate check of county burn-ban status; this drought reading does not establish whether burning is allowed. The index is a measure of dryness, with 0 representing saturated soil and 800 extreme drought. A lower daily average describes movement in that measure, not a change in county burning rules.
The 17-point decline is a comparison with the previous day, not a forecast. The next Forest Service summary will show whether the county average continues to fall or rises again. Readers can inspect the Comal County row in the Forest Service’s index to compare the average, range and daily change.
