If you are anywhere near a flood that covers an area greater than the size of France and Germany combined, some unsolicited advice: don't park near a river.
An office worker captured footage of a fast rising river in Toowoomba, Australia. The river soon gave way to a flash flood that swept away cars parked along the river's bank. One by one, the river floated them downstream. One brave (or foolish) man rescued his SUV from the deluge, but the rest of the vehicles ended up dogpiled against a bank of trees.
Fortunately for the videographer, his car was parked in the front of the office building that day.
