How often do the fire boundary lines (on Inciweb and/or WatchDuty) usually get updated?
If I'm not mistaken, the outline has been the same since yesterday, when it was listed at under 100 acres. Overnight, Joe Schmoe noted the fire was already much larger than the boundaries showed. At 10:50 this morning, they updated to 115 acres with no change in the boundary drawing. And now, the size is listed as as 588 acres, but I don't think the lines have changed.
Naturally, I'm interested in the direction(s) it is moving and growing...
***EDIT: A little while after I posted, it looks like Inciweb updated their map, and WatchDuty hadn't yet updated theirs. Just visually comparing the two, it looks like most of the spread has been toward the south and east, with some westward as well. I don't know the geography in that area, but based on the satellite views, it looks like a natural fire break (perhaps one of the feeders into Lytle Creek?) has, as of now, stopped the fire from spreading northward.
