A remarkable video from a beach in Santa Cruz, California shows an enormous and ominous cloud come sweeping across the sky.
To the bewilderment of beachgoers, the huge cloud briefly darkened the sky and actually caused temperatures to drop as it blocked out the sun.
Fortunately for those hoping for a fun day at the beach, the 'fognado' only last a few minutes as it quickly exited the area and conditions returned to normal.
Although the odd event appeared rather spectacular, meteorologists say that there was nothing particularly paranormal about the 'fognado' and that it was actually just a massive weather phenomenon known as a 'roll cloud.'
