Flooding

The Allegheny River remains frozen, and there is still ice on the Monongahela and Ohio Rivers, though barge traffic is getting through. Now, with rain forecast for the next couple of days the concern turns to flooding.

“There’s always a threat of flooding, particularly when you have ice and when it starts to move it can jam up in narrow valleys or behind bridges and cause water to rise behind the jam very quickly,” said Lewis Kwett, hydraulic engineer with the Pittsburgh division of the U.S. Army Corps of Engineers.

County, state and federal teams will finish conducting damage assessments Friday afternoon after flash floods and severe weather plagued the Pittsburgh region.

Alvin Henderson, chief of Allegheny County Emergency Services, said he and his teams are trying to restore a sense of normalcy.

“We’re working as quickly as we can to try to collect this data so we can find out what forms of assistance we’re hopefully going to be able to receive,” he said.

Assessment teams first visited areas hardest hit by the flooding.
