.. this is the third comment of the National Geographic article above ..
The link below will always display the most recent perimeter of the Rim Fire and current hot spots straight from the GeoMAC server. This is the same server that also provides data to the crews on the fire line. Sometimes the data on the InciWeb site is not as current as the data that comes from the GeoMAC server. (The InciWeb site gets its data from GeoMAC.)
The map also shows wind speed and direction. Note that the wind data is always 3 hours old.
For more information regarding this map, you can follow the “About” link in the upper left corner of the map.
