Lightning and hail storms described by locals as like walking through a 'zombie apocalypse' have caused flooding and travel chaos in Brighton.
The storms hit the Hove, Brighton and Worthing areas of Sussex at the start of the morning rush-hour, causing disruption to trains along the south coast.
Lightning which struck an electricity sub-station caused power cuts to the coastal rail route, although the main line to London was running normally, Network Rail said.
Most services have resumed to normal now but earlier delays of up to 30 minutes were expected until at least 9am this morning and could extend beyond that.
Staff at Brighton Station described the hail storms as being like a 'zombie apocalypse.'
The weather is a far cry from what it was in Brighton when temperatures hit 28C last week.
