Harrisburg, Pa. – Flood concerns are mounting across Pennsylvania today as a warm front triggers widespread rainfall, with some areas expected to receive more than two inches of rain by early Wednesday.
According to the National Weather Service’s Middle Atlantic River Forecast Center, the heaviest precipitation will hit central and western Pennsylvania, with totals topping two inches in localized spots. Rain is expected to continue through the evening and overnight hours, raising the threat of urban flooding and river rises.
River gauges along the Juniata, Susquehanna, and Monongahela are already nearing Action Stage, with forecasters warning that multiple points could cross thresholds that trigger flood monitoring. Low-lying roads, underpasses, and small creeks are at particular risk.
Drivers across Pittsburgh, Altoona, and Harrisburg should avoid travel during high-intensity rain bands. Emergency managers advise residents to secure loose items outdoors, clear storm drains, and monitor local alerts for updated flood advisories.
Today’s system is part of a broader June pattern that has brought above-average rainfall to the Mid-Atlantic. The warm, moisture-rich air mass is expected to move northeast into New York and New Jersey by Wednesday.
Rainfall is expected to taper off by mid-morning Wednesday, but more advisories may be issued as rivers continue to respond.
