A funnel cloud – a funnel-shaped cloud of condensed water droplets – was spotted at about 2.30 pm.
Joanna Chambers, duty forecaster for Jersey Met, said several sightings had been reported to them. She explained that the funnel would be classed as a tornado if the spout touched the land. Similarly, if the spout touched the sea it would be called a waterspout.
'It is a bit like a mini tornado,' the forecaster said. 'They tend to come out of cumulonimbus clouds which tend to be quite unstable.' On average Britain experiences 33 tornadoes per year.
