As with Ohio, Illinois, Indiana and New York state, the warmer weather. Four consecutive days of temperatures over 50 degrees Fahrenheit in the state brought with it snow melt, rain and ice jams, has also caused flooding around the state of Pennsylvania.
At one time the Ohio River at the Point in Pittsburgh was threatening to break it banks and cause flooding at Monongahela Wharf. The threat now appears to have passed, and the level of the river was around 1 foot (30cm) lower than flood stage as of this morning, Sunday 23 February 2014, where it stood at 16.6 feet at 8 a.m.
According to this report, a flood warning remains in the counties of Clarion and Armstrong where an ice jam on the Allegheny River is threatening some flooding.
Over the weekend there was an ice jam along Oil Creek in Venango County, Pennsylvania, where as many as 70 people had to evacuate their homes.
It is a similar story in Bolivar, Westmoreland County, where 6 people had to evacuate and 2 rescued after a severe ice jam caused flooding there.
