Across the pond, The Mirror in the UK reports Killer Typhoon Hagibis is set to cause days of washouts and 50mph gales to Britain as the tempest on the other side of the world strengthens Atlantic storms.
Forecasters said Hagibis, Japan's worst typhoon for 60 years, is set to impact weather 10,000 miles away in Scotland by making the rain and wind even worse, creating new flood fears.
Hagibis' effects are expected in the second half of the week, said forecaster John Hammond of weathertrending, after the Met Office issued a yellow warning for much of England.
Met Office forecaster Marco Petagna added: "Some of Typhoon Hagibis' energy might well get caught up in North Atlantic weather and could develop low pressure areas close to the UK."
