Animals at ZooAmerica have been moved to higher ground and placed in temporary homes due to rising waters on the Swatara Creek.
The staff has moved nearly two dozen animals to protected locations around the wildlife park at Hersheypark, and will continue to move more animals as a precautionary measure, according to a statement on the zoo's Facebook page.
All animals at ZooAmerica are safe, park staff said in the statement.
According to the statement, ZooAmerica was closed Friday so that the staff could closely monitor weather conditions and focus on the well-being of the animals.
Two bison at ZooAmerica died during the flooding that resulted from Tropical Storm Lee in September 2011.
The U.S. Department of Agriculture later cleared the wildlife park of any wrongdoing, and said zoo officials took appropriate steps as the creek flooded the animals' pen.
