What the Fog?! Californians Witness the End of the World

In this eye-popping video, a huge fog cloud can be seen sweeping across the Natural Bridges Beach in Santa Cruz, California.

According to witnesses who captured the footage on August 2, it was really hot that day. Suddenly the sky darkened and the wind picked up, and then this massive fog cloud rapidly rolled in. "Umbrellas were flying, sand was pelting me in the face and people were quickly leaving the beach. After only a few minutes, the fog cloud passed and the sun came out," the author of the video wrote.
