I learned a new word today. "Extratropical cyclone".
The Environment Agency has issued 24 severe flood warnings.
The latest warnings are for various places along the south coast of England.
The Met Office said that following the heavy rain that had fallen in many places during the day, it expected "potentially damaging" severe gales in southern England during the evening and into Saturday morning.
BBC Weather's Peter Gibbs said that with gusts of up to 80 mph likely, there was a danger of high tides bringing fresh coastal flooding.
About 2,200 armed forces personnel - regulars and reserves - are helping the flood relief effort and a further 3,000 are on standby to respond within two hours. Flood defenses in Gloucester are succeeding in holding back the water, according to the Environment Agency. Council staff in Hampshire have been moved from their "normal day jobs" to help the flood relief effort. The prime minister said UK businesses were offering "free help" to those affected by the flooding. Major supermarkets are providing supplies such as waders, food parcels, batteries and torches.
Police have appealed to drivers across Northern Ireland to take extra care as rain and snow disrupt travel.
