            Social media user on X (formerly Twitter)
            posted a few pictures of a small funnel
            cloud in response to one of our posts.
            Location is approximate but nearby Mission
            Peak Regional Park. Pictures are also
            consistent with an ALERT CA camera capture
            located on Mission Peak.
