The National Weather Service says a tornado has touched down at a Navy air station in Point Mugu.

Meteorologist Curt Kaplan says a waterspout washed ashore at about 7:15 p.m Thursday, tearing the roof off of a building at Naval Base Ventura County.

Vance Vasquez, a public affairs specialist at the naval base confirms "a good portion" of the roof was torn off of Hangar 351, which houses air craft.

Vasquez says debris was scattered on the tarmac and part of the runway, but flight operations at the base were not impacted. There are no reports of any injuries.
