Chunks of ice made their way down the Sandusky River Sunday.
National Weather Service issued a flood advisory for ice jam flooding in central Seneca and Wyandot counties and eastern Sandusky County until 11:15 a.m. today.
Minor flooding was being reported along parts of the Sandusky River and its tributaries due to ice jams, according to the weather service.
Dan Stahl, director of Seneca County Emergency Management Agency, said he was unaware of any flooding issues in Seneca County Sunday. He said he looked at the river downstream from Tiffin, and it was flowing without any problems.
"The river is flowing," he said.
Stahl said ice in the river is a normal occurrence. An ice jam occurs when ice creates a small dam and forces the river level to increase.
"It's just like building a small dam on the river," he said.
According to the weather service, ice jam flooding is difficult to predict, and conditions can change rapidly.
Stahl said Tiffin Fire Rescue Division measured the ice Thursday, and it averaged about 5 inches in thickness. National Weather Service wanted the information to help with its forecasting, he said.
