The Susquehanna River in Wilkes-Barre is expected to crest near 25 feet Thursday afternoon, according to the most recent forecast by the Middle Atlantic River Forecast Center.
At that level, the lowlands of Shickshinny, West Nanticoke in Plymouth Township and Plainsville in Plains Township are threatened by the river.
The Wyoming Valley Levee System protects most of the Wyoming Valley of a river level up to 42 feet as the natural flood stage is 22 feet.
The last time the river exceeded the natural flood stage occurred Jan. 25 when an ice jam in the Exeter, Jenkins Township areas broke causing the river to hit 27.4 feet in Wilkes-Barre. The ice jam caused minor flooding along Susquehanna Avenue in West Pittston, Duryea and the lowlands of Pittston.
While a flood watch remains in effect for most of Northeastern Pennsylvania, the extreme northwest corner of Luzerne County was under a flash flood warning that was set to expire Wednesday morning.
The flash flood warning incorporates Ricketts Glen State Park, which closed the popular Falls Trail due to high water by Kitchen Creek.
Also, Knoebels Amusement Resort in Elysburg is closed Wednesday due to flooding by Roaring Creek.
More rain is in the forecast with heavy rain in thunderstorms.
Creeks and streams in the Wyoming Valley are running high but have not flooded.
