I’m sure there was a similar peak in 2009 for the Station Fire. I remember seeing the pyrocumulus cloud in Glendale/Pasadena all the way down to San Diego.

It’s also the last time that Mt. Wilson was threatened, though tonight it’s from the East side of the mountain. I’m watching closely because I’m 8 miles from the Bobcat Fire to the East and we’re under an evacuation warning. Fortunately the live cam has some reasonably clear footage of the immediate danger as the observatory is 4 miles up the hill above us.

Bobcat Fire update
I’m just South and slightly West of the Wilson Observatory which is at the top of the mountain just above our house. Fortunately we’re not in any of the preliminary evacuation zones which are all immediately South of the fire. We won’t really need to worry heavily unless it gets closer to the observatory.
