An interactive map shows where lightning strikes are occurring as the North East is braced for thunderstorms from tomorrow.
LightningMaps shows in real-time where strikes and flashes occur with a simulation of the event rendered over the affected area.
Using a network of station operators, who have their own lightning detectors, the map is based on hundreds of them to transmit their data as soon as it happens.
It means there could be a slight delay in the playback of a lightning strike, but it is believed to carry a high accuracy rate in the reporting of location and time.
