The ice storm warnings in Nebraska have all expired but the experts say a new threat is emerging with the incoming warmer weather — ice jams on the state’s waterways.
National Weather Service meteorologist Brad Small says as the temperatures climb into the 40s today, we may start to see flash flooding along our rivers.
“So, as all of this ice that’s accumulated on the grass thaws and releases into the streams and we get a little more melting, including the ice jams, the potential for those ice jams will increase,” Small says.
There’s little that can be done to prevent ice jams from happening he says, and they can quickly lead to flash flooding.
“The ice just bottles up and blocks up the flow and anywhere upstream of that potentially could see flash flooding and then downstream, the river’s levels may sink down a bit until the ice jam breaks,” Small says. “Certainly, flash flooding is a possibility. You could get water and even ice chunks in your yard. You’re pretty much at the mercy of the river.”
Any ice that accumulated in Monday’s storm should be gone soon. Forecasters say high temperatures should remain generally in the 40s now through the weekend.
