Got the image above from MODIS. It shows hot spots found by satellite. As we see, the hot spots (all orange dots) are up the Little Tujunga Canyon in the mountains next to Sunland and San Fernando, just above the Foothill Freeway.
So far the only blog report I see by that tag is Mary Lu’s. (Why does Google Blogsearch still not search for tags?) Others reporting: Firefighter Blog, W.I.S.E. Fire Tracking Site, Wildfire Today and LAist.
I learned from the CA Santa Ana/Fire thread on a weather forum that it’s also called the “Little T Fire”, I’m sure because it’s in Little Tujunga Canyon.
GEOmac doesn’t seem to have anything about either fire yet. Nor MODIS’ big map. Too small, I guess. But you can download the .kml file that displays the satellite-detected hot spots plotted in Google Earth. (You can do .wms from that same page too, but I’m new to that one.)
