EASTLAKE, Ohio -- The warm-up thawed some of the ice and snow but it could create problems.
The potential for flooding has several communities watching and waiting.
The sudden shift in temperatures from below freezing to 50 did little to raise the water level along the Chagrin River in Eastlake.
As of Thursday morning, the river was very still with a layer of ice between 10 and 12 inches thick coating the top.
The concern is how quickly that sometimes changes.
FOX 8 Meteorologist Scott Sabol said the flooding probability is climbing. See the river level forecasts here.
"The water is below the level we are used to so it would take a significant amount of rain. The chief predicts we would need two to three inches of rain before we would have any problems," said Eastlake Mayor Dennis Morley.
