Pennsylvania: Ice jam flooding on Allegheny River
Ice jams in Pennsylvania are causing the Allegheny River to flood...
People in Rimerton are now dealing with flooded homes and roads.
Ice jams form when ice freezes on the river and flow downstream and gets caught up on locks, dams and river bends.
Some residents say things will get worse before they get better...
The Coast Guard and the Army Corps of Engineers are keeping a close eye on the river.
When the river starts flowing again, rushing water and ice can damage boats and other property downstream.
