Lisbon weather: Waterspout looms over Vasco da Gama bridge

A large waterspout - a rotating column of mist and spray - has been spotted over the Vasco da Gama bridge in the Portuguese capital, Lisbon.

Video shows the waterspout rising above the waters of the Tagus Estuary on Thursday.

Waterspouts are similar to tornadoes, but they form over a body of water.
