Weather warnings strong winds apply across south-west England, the Midlands and the South East, and for wind and rain in Wales, whilst flood warnings are in place for Wales and southern England as the weather system moves east.
BBC weather forecaster Laura Gilchrist said: "This weather would not be unusual in October or November, but as it's coming in June the trees are more in leaf and people are carrying out more outdoor activities than then, so there's more risk of disruption than at other times of the year."
Many trees have been uprooted in the South, and a pre-Olympic canoe slalom competition has had to be postponed in Cardiff.
However, things are looking brighter for the weekend, with more sun and less wind on Saturday (finally!).
