Unusual weather in the Western US has caused an apparent "swap" in weather conditions between two states.

In Phoenix, Arizona, which is famously dry at this time of year, heavy rain caused a canal to flood leaving more than a dozen people marooned on flooded streets.

Meanwhile in Washington State, an enormous dust storm rolled over parched land, creating an eerie scene and causing numerous traffic accidents.
