Rare Waterspout Touches Down On Lake Berryessa

NAPA COUNTY (CBS) -- A fisherman on Lake Berryessa in Napa County didn't catch any trout Wednesday, but he did capture video of a rare waterspout.

The clip, provided by Matt Allen's Bassin Guide Service, showed the spout briefly touching down on the lake at around 2:30 p.m. Wednesday afternoon.

A second video clip of the spout was posted on YouTube.

The waterspout was a type referred to as a "tornadic waterspout," or essentially a tornado that formed over water. They have the same characteristics as a land tornado and often appear amid severe thunderstorms and are sometimes accompanied by high winds, large hail and lightning.

The waterspout was driven by the same storm caused hail and lightning from Angwin south and east to Fairfield.
