Rainfall intensifies through Tuesday across the Mid-Atlantic
A slow-moving low-pressure system is set to drench much of the Mid-Atlantic through early Wednesday, bringing persistent rain and potential flooding concerns—especially in central and western Pennsylvania, parts of New Jersey, and southeastern New York. As of today, Monday, May 26, rain has already affected northern Pennsylvania, New Jersey, and the Hudson Valley, but the most intense precipitation is still on the way.
Central and western Pennsylvania under the heaviest threat
According to the National Weather Service’s Middle Atlantic River Forecast Center, the heaviest rainfall totals are forecast for central and western Pennsylvania, including cities like Harrisburg, Pittsburgh, and Scranton. These areas could accumulate 1.5 to 2 inches (approximately 38 to 50 mm) of rain by Wednesday morning. Commuters in these urban centers should prepare for ponding water, reduced visibility, and slower travel during peak hours.
New Jersey and southeastern New York in line for soaking rain
In New Jersey, rainfall will spread southward and intensify along the I-78 corridor, where totals may exceed 1 inch (around 25 mm). Southeastern New York, particularly the Hudson Valley, could also see substantial accumulations, creating slippery roads and minor runoff issues.
Rivers remain below flood stage—for now
While river flooding is not currently anticipated, officials urge residents in low-lying areas and urban zones to stay alert. The ground is already saturated from recent rains, increasing the potential for localized flooding and blocked drainage systems. Authorities advise taking precautions such as clearing storm drains, charging essential devices, and avoiding flood-prone routes.
Storm tapers off by Wednesday morning, but updates still likely
Rain is forecast to gradually taper off by mid-morning Wednesday, but the system may still prompt updated advisories as it moves east. Stay tuned to local alerts for evolving conditions through Tuesday night into early Wednesday.
