There are two types of waterspouts i.e.
tornadic and fair-weather.
The clouds from which waterspouts descend are much fast-moving, so fair-weather waterspouts are often static.

The average spout is around 50 metres in diameter, with wind speeds of 80 kilometres per hour.
‘Most waterspouts final for up to one hour, though average lwhetheretime is just 5 to 10 minutes&, he added.The formation of a waterspout takes place over five stages; first stage is formation of a disk on surface of water, known as a dark spot; moment stage is a spiral sample on water surface; third stage is a formation of a spray ring; fourth stage is where waterspout becomes a visible funnel; and lwhetherecycle ends and fwhetherth stage where waterspout decays.
