Coastal Flooding Threat in Mid-Atlantic as Low Pressure Strengthens
A strengthening area of low pressure is moving into the Northeast, raising concerns about “significant” coastal flooding across parts of the mid-Atlantic this coming Sunday and Monday. In response, New Jersey has declared a state of emergency ahead of the storm.
The weather setup involves strong, consistent northeasterly winds combined with high tides, leading to elevated wave activity along the East Coast, stretching from Virginia to New England. Current forecasts indicate that the heaviest flooding is likely to hit the coasts of New Jersey and Delaware, especially around Delaware Bay.
A coastal flood watch is in effect for Sunday and Monday, with waves potentially reaching 12 to 15 feet. Some areas could see tides exceeding the average by 2 to 4 feet.
“Moderate to major coastal flooding impacts are becoming increasingly likely,” forecasters noted during a briefing on Friday. The National Weather Service offices in Mount Holly, New Jersey, warned of widespread flooding, road impassability, damage to buildings, and even possible evacuations from Sunday into Monday.
A state of emergency has been declared for all 21 counties, effective at 10 PM on Saturday. The governor emphasized that a nor’easter is anticipated to bring heavy rain, wind, and potential flash flooding over the weekend.
Forecasters have warned that high waves could lead to considerable dune destruction and coastal erosion. Additionally, there is a high wind watch from Long Island to the coasts of New Jersey and Delaware, with wind gusts potentially reaching 90 mph. Sustained winds of 25 to 35 mph could further aggravate wave conditions. Due to the impending storm, ferry services to Fire Island have already been suspended in New York.
Inland areas may also face flash flooding as heavy rains are expected. The coast could see accumulations of 3 to 5 inches of rain through Tuesday. The National Oceanic and Atmospheric Administration has issued a Level 2/4 flash flood risk for areas stretching from Norfolk, Virginia, to Philadelphia, New York City, and into Southern New England.
