Mississippi River flooding has affected at least eight U.S. states since January, and it has become the longest-lasting since the "Great Flood" of 1927, the National Weather Service said Tuesday.

美国国家气象局(National Weather Service)周二5月28日表示，自1月份以来，密西西比河洪水已经影响了美国至少8个州，成为自1927年“大洪水”以来持续时间最长的洪水。

This year's flooding is a result of early spring snowmelt and record-breaking spring rain, The Weather Channel said. Since the start of 2019, many parts of the lower Ohio and lower Mississippi river valleys have received more than two feet of rain, with some spots having over 40 inches of rain.

天气频道说，今年的洪水是早春融雪和破纪录的春雨的结果。自2019年初以来，俄亥俄州下游和密西西比河下游流域的许多地区都有超过2英尺(24英寸)的降雨量，有些地方的降雨量甚至超过40英寸。

As of Tuesday, about 380 river gauges have reported levels above flood stage in central United States. Among them 71 gauges reported major flooding, 105 moderate flooding and 206 minor flooding, the weather service reported.

截至周二，美国中部约有380个河流水位计显示水位高于洪水水位。气象部门报告，其中71个水位计预警大洪水水位、105个中等洪水水位和206个小洪水水位。

No deaths have been reported in the river flooding along the Mississippi, according to a USA Today report.

据《今日美国》报道，密西西比河沿岸的洪水没有造成人员伤亡。

Hundreds of people died in the 1927 flooding, which remains the benchmark flood event for the country's biggest river.

1927年洪灾造成数百人死亡，至今仍是美国最大河流的标志性洪水事件。
