Britain is on tornado alert after weather experts issued a warning.
The Tornado and Storm Research Organisation (Torro) forecasts isolated severe thunderstorms or weak tornadoes during the next few days.

The warning, published on Torro's website, applies to parts of south-west England, east Wales, South Wales and much of southern, central and eastern England.

"The highest tornado risk would appear to be along and close to the south coast,'' it said.

More than 20 properties have already been affected by what is believed to have been a tornado in west Wales.

Emergency services were called to Bow Street in Aberystwyth after damage was caused by high winds.

A spokesman for Dyfed Powys Police said: "It was apparent that what is believed to be a tornado had struck parts of the village. Commercial and residential premises, vehicles and caravans were damaged.''

No one was thought to have been injured.

Rachel Vince, forecaster at the MeteoGroup UK, said: "We have had reports of a tornado near Portsmouth on Saturday. The main concern is general wind and heavy rain through the next 24 to 48 hours.''
