What's with the funky looking cloud over Covington?

    MAPLE VALLEY, Wash. -- A surreal sight popped up over the foothills as a big hole appeared in cloud deck midday Thursday.

    The "rip" in the clouds is actually called a "Hole Punch" cloud, or some call it a "Fall streak cloud.

    It's a pretty simple explanation: They're caused by the airplanes.

    When a plane either ascends or descends through that particular type of cloud, it creates a hole in the cloud.

    The clouds are made from super-cooled water droplets that freeze and "fall" out of the cloud when the plane passes through
