美国有线新闻 CNN 美国遭遇洪水侵袭 致10万家庭和企业断电（在线收听）

Slow moving storms have soaked parts of Texas and Louisiana this week and millions of people in the region are under flash flood watches into Thursday.

本周，缓慢移动的风暴浸透了得克萨斯州和路易斯安那州的部分地区，该地区数百万人一直到周四都处于洪水警戒中。

Relentless rain, in some areas more than a foot of it is only part of the story.

在一些地区，无情的雨水超过一英尺深，但远不只如此。

Strong winds have also blown over trees and damaged some buildings.

强风还吹倒了树木，毁坏了一些建筑物。

The power was out for 100,000 Texan homes and businesses on Wednesday morning but by the afternoon that number had been reduced to 29,000.

周三上午，得克萨斯州10万户家庭和企业断电，但到了下午，这一数字已降至2.9万。

In neighboring Louisiana, at least four deaths have been blamed on the weather this week

在邻近的路易斯安那州，至少有4人因本周的恶劣天气而死亡，

and with more rain in the forecast through Friday, some areas of Oklahoma and Arkansas are also on the lookout for possible flash floods.

而且由于预报称周五还将迎来更多降雨，俄克拉荷马州和阿肯色州的一些地区也在警惕可能发生的山洪暴发。

In the U.S. flash floods kill more people than tornadoes, hurricanes or lightening.

在美国，山洪灾害造成的死亡人数比龙卷风、飓风或闪电要多。

A flash flood creates a rush of moving water that can sweep a grown man off his feet, a car off the road and even your entire home off its foundation.

山洪会带来大量流动的水，可以冲倒一名成年男子，冲走一辆汽车，甚至将整座房屋拔起而起。

When the ground becomes so saturated that water can no longer seep into the soil,

当地面被浸透，水不能再渗入土壤时，

it begins to run off quickly into rivers and streams and this causes a rise in water in a flash.

它会开始迅速流入河流和溪流，继而导致水位瞬间上升。

Densely populated areas have an extremely high risk of flash flooding

人口稠密的地区有着极高的山洪暴发的风险，

with the additional concrete and less grassy areas for the water to soak into the soil and they can see flash flooding very quickly.

这些地区混凝土较多而利于水渗入土壤的草地地区域较少，因此很快就会出现山洪暴发。

In mountainous terrain, the combination of gravity plus the easy runoff

在山区，重力因素加上轻易形成的径流，

can lead to catastrophic flooding when all of that water's funneled into rivers, creeks and even the valleys.

当所有的水都流入河流、小溪甚至山谷时，会导致灾难性洪水。

Remember, flash flooding can happen in the blink of an eye.

谨记，山洪暴发可能发生在眨眼之间。

That's why it's important to stay alert and pay attention in case a flash flood watch or warning is issued for your area.

因此，保持警惕和注意非常重要，以防你所在地区发布山洪暴发警戒或预警。
