当地周三，美国东北部超1000万人收到洪水预警，此前本周早些时候给中西部部分地区带来龙卷风的风暴系统正在向新英格兰地区移动。
美国国家气象局为纽约州、康涅狄格州、马萨诸塞州、新罕布什尔州和佛蒙特州的大片区域发布了洪水预警，预警将持续至周三晚间或周四下午。预报员表示，包括纽约市、波士顿、康涅狄格州哈特福德以及缅因州波特兰在内的多个大都市地区都可能受到影响。
纽约州首府奥尔巴尼同样处于风险之中。周三上午，预报员为奥尔巴尼及周边地区发布了山洪预警，雷达数据显示当地已降下1至3英寸降雨，山洪“正在发生或即将爆发”。预计到下午，当地还将迎来最多2英寸的额外降雨。

据CBS纽约报道，纽约市周二强雷暴天气对应的山洪预警已于周三上午解除。但市政府官员警告称，周三即使遭遇短时暴雨，也可能导致街道积水漫溢、地下室或一层住宅被淹。
哈特福德和马萨诸塞州斯普林菲尔德的山洪风险最高，预报员称当地出现过量降雨的概率中等。新英格兰部分地区累计降雨量可达2至5英寸，可能对近日已被此前风暴淋湿的多处区域造成威胁。
美国国家气象局波士顿办事处针对康涅狄格州大部和马萨诸塞州西部发布的洪水预警中提到：“过量径流可能导致河流、小溪、溪流及其他低洼易涝地区出现洪涝。”该办事处还指出，小溪和河流可能溢出堤岸，进而在城区和排水设施不完善的区域引发积水。

周二至周三期间，美国东部地区共收到84份山洪报告。纽约上州在此期间的降雨量最高，奥尔巴尼累计降雨量超过6英寸，为全美之最。
预报员敦促处于洪水预警区域的民众全天关注风暴动态，部分预警可能从预警升级为警报，意味着洪水影响从潜在风险变为迫在眉睫的威胁。
美国国家气象局提醒：“居住在易涝地区的民众应做好准备，一旦发生洪涝即可采取应对措施。”

More than 10 million people were under flood alerts across the northeastern United States on Wednesday, as a storm system that brought tornadoes to parts of the Midwest earlier in the week moves into New England.
The National Weather Service issued flood watches for large chunks of New York, Connecticut, Massachusetts, New Hampshire and Vermont that were set to remain in effect until Wednesday night or Thursday afternoon. A handful of metropolitan areas could be impacted, including New York City; Boston; Hartford, Connecticut; and Portland, Maine, forecasters said.
New York’s capital city, Albany, was also at risk. Forecasters issued a flash flood warning for the capital and surrounding areas Wednesday morning, as radar showed 1 to 3 inches of rain had already fallen and flash flooding was “ongoing or expected to begin shortly.” Up to 2 more inches of rain were expected by the afternoon.

In New York City, a flash flood warning for Tuesday’s intense thunderstorms had expired by Wednesday morning. But city officials warned that even brief downpours on Wednesday could cause rushing water through streets and inundate basements or first-floor residences, CBS New York reported.
Flash flood risks were highest for Hartford and Springfield, Massachusetts, where forecasters said there would be a moderate chance of excessive rainfall. Between 2 and 5 inches of rain could fall in different sections of New England, potentially imperiling a handful of places already drenched by previous storms in recent days.
“Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations,” the weather service’s office in Boston wrote in a flood alert covering much of Connecticut and western Massachusetts. It noted that creeks and streams “may rise out of their banks,” potentially triggering flooding in urban areas and others with poor drainage infrastructure.

There were 84 flash flood reports across the eastern U.S. between Tuesday and Wednesday. Upstate New York saw the highest rainfall totals in that period, with Albany receiving more than 6 inches, which was the greatest amount.
Forecasters urged people in areas under flood watches to keep up with possible storm developments throughout the day, as some of those alerts may be upgraded from watches to warnings, reflecting a shift from possible to imminent flooding impacts.
“Those living in areas prone to flooding should be prepared to take action should flooding develop,” the weather service said.
