As Britain votes on whether to leave the European Union, storms raged across the country and polls showed inconclusive results. Polling stations have been moved because of flooding, cars were stranded, and transportation throughout London has been disrupted due to the heavy rain. The weather isn’t expected to let up until Friday, forecasters report. Prime Minister David Cameron called the vote over pressure from Euroskeptics in the Conservative Party and the UK Independence Party. The Leave campaign claims the British economy would benefit from the move, though Cameron and most independent economists argue that it would cause poverty and financial chaos. The referendum—capping a four-month campaign—has split the nation.
