Heavy rains northwest of Pittsburgh are expected to cause minor flooding in New Kensington and close the Mon Wharf tonight, according to the National Weather Service.
The Monongahela River is expected to rise to 19.3 feet by this evening, meteorologist Ken Herald said. The wharf begins to flood when the river reaches 18 feet.
The wharf was open for parking this morning but vehicles were not allowed on the lower part of the facility.
A flood advisory was to remain in effect through Friday afternoon for Allegheny County. A slight chance of thunderstorms was forecast before 1 p.m., with a high in the mid-70s. The Memorial Day weekend forecast called for a slight chance of rain on Friday and Saturday with highs around 70, and spectacular weather Sunday and Monday, with temperatures pushing toward 80.
A flood warning has been issued for the Allegheny River near the C.W. Bill Young Lock and Dam, Mr. Herald said. The river is expected to crest at 17.4 feet at 8 p.m. today -- just more than the flood stage of 17 feet, he said. Only riverbanks are expected to flood, as New Kensington would be affected at 17.7 feet.
