Intensive preparations are underway on the American east coast for the arrival of Hurricane Sandy. More than 40 people were killed when the hurricane cross the Caribbean. As Zoe Convey reports from Washington, the hurricane is expected to develop into a superstorm as it joints with two other powerful weather systems.

为了应对即将来临的飓风桑迪，美国东海岸正紧锣密鼓地做准备。飓风袭击加勒比时夺走了40多人的生命，Zoe Convey从华盛顿发来的报道称，预计飓风与另外两个强大的天气系统相遇时会发展为超强风暴。

It would be bad enough if America was expecting the arrival of the hurricane, instead meteorologists are predicting that three weather systems are said to collide. It will hit cold air heading south from Canada and a wintry storm coming from the American west, that will give Sandy more energy. But that doesn't mean the superstorm will be in a hurry. What's worrying the experts is that it could sit for several days on the coast bringing misery to New England in the north all the way down to Virginia in the south and spreading as far west of Ohio.

如果说美国要迎来飓风就够糟糕的了，那么气象学家称预计有三个天气系统将相遇。桑迪飓风遇到来自加拿大的向南的冷空气，并遇到来自美国西部的暴风雪，这样桑迪的威力就更强大。但这并不意味着超强风暴来得快去得快，令专家担心的是，它将在海岸停留数日，从北部新英格兰一路到到南部维吉尼亚都会遭受袭击，同时它将蔓延到西部的俄亥俄。
