Earlier today at about 2 p.m. the Chimney Fire experienced a wind shift and exploded across the open country southwest and adjacent to Lake Nacimiento. Below are three images of the resulting pyrocumulus cloud that was generated over the convection column. In the fire business they refer to it as "capping out."
