More bad weather.

A strong solar storm is expected to hit Earth shortly, and experts warn it could disrupt power grids, satellite navigations systems and plane routes.

The storm - the largest in five years - will unleash a torrent of charged particles between 06:00 GMT and 10:00 GMT, US weather specialists say.

They say it was triggered by a pair of massive solar flares earlier this week.

It means there is a good chance of seeing the northern lights at higher latitudes, if the skies are clear.

The effects will be most intense in polar regions, and aircraft may be advised to change their routings to avoid these areas.

In the UK, the best chance to see them will be on Thursday night, the British Geological Survey says.
