Smoke visible

This was taken from my front door. at about 7.15pm facing South.  The cumulus pile is above a fire on the other side of Black Mountain from us. The dirty brown stuff on the right hand side is the smoke plume from a grass fire in the rural part of San Mateo county - there was dramatic underlighting from the setting sun under it shortly afterwards, by which time the nearer plume obscured the further pile.  In extras, the screenshot of the firealert camera on the top of Black Mountain, and the screen which shows its viewpoint on a map. 
Too hot continues. 37C in the afternoon and over 35C well into the evening. No surface wind to speak of.
