Heavy rain overnight caused serious flooding across parts of upstate New York, leaving roads underwater and prompting officials to warn people to avoid travel. Authorities said residents should stay off the roads unless they are leaving an area threatened by flooding.

The flooding was severe enough to push Schoharie Creek to flood stage in Prattsville, adding to concerns about rising water and dangerous conditions. The warning reflected the risk of fast-changing floodwater, which can make roads impassable in a short time.

In Colonie, torrential rain flooded Exchange Street, illustrating how quickly water built up in low-lying and heavily traveled areas. Officials were also preparing to evacuate buildings near Sumpter Street as conditions worsened.

The storm left communities across the region dealing with inundated streets and the possibility of more emergency action if water levels continue to rise. With roads described as dangerously flooded, the focus remained on public safety and limiting travel until conditions improve.
