A very strong thunderstorm went through a portion of Contra Costa County near Brentwood and Discovery Bay on Saturday, January 23rd. The following pictures were taken by Diane Rybicki of the Contra Costa Water District and are used here with her permission and the permission of the Contra Costa Water District.

A low topped super cell produced an EF0 tornado near Brentwood. The tornado crossed power lines and destroyed a utility pole. An eyewitness described the tornado as high winds from swirling white cloud. The pole was twisted to the ground and the top one-third of the 40-foot pole was splintered. Fifty-five customers lost power at 12:54 p.m. PST.
