I’ll preface by saying I am not an expert at reading satellite data, but I will do my best and hope to be corrected in the comments. Here is the latest image from the Forest Service data loaded into Google Earth, screenshotted at 7:20 AM, September 27.
The original cluster from yesterday at 1:00 PM is still visible, and the time stamps haven’t changed — in other words, the data doesn’t say they were still hot at 11:00 PM. That means the satellite data is probably not a very good predictor of what didn’t burn — only what did burn.
The new cluster north of the original shows 6 additional hot spots. These data points were stamped at 11:00 PM last night, except for the bottom right square which is stamped at 2:00 AM.
To make this image yourself, download and install Google Earth (it’s free). Then visit the Forest Service’s Fire Data in Google Earth page and click on the KML link labeled Fire Radiative Power: Current. If your browser asks, tell it to open the KML file in Google Earth.
