A flood warning is in place for parts of Armstrong County until 5:30 p.m. as rain and higher temperatures could lead to ice jam flooding.
The warning covers areas near the Allegheny River in northern Armstrong County south of Foxburg and downriver beyond Parker and nearby parts of Clarion County. The National Weather Service issued the warning after ice on the river broke free and was seen heading downriver from the Foxburg area.
