Ice jams have already formed on the Platte River near Fremont. One continues upstream for 2 to 3 miles, according to the Papio-Missouri River NRD.
An ice jam forms on the Platte River west of the Highway 77 bridge near Fremont on Monday. Observers in eastern Nebraska will be looking out for signs of flooding as the weather warms up. “We’re just waiting to see how the snow will melt over the next couple of days,” said hydrologist David Pearson of the National Weather Service office in Valley. “We’ll be watching closely.”
An ice jam on the Platte River near Fremont. Average high temperatures in the mid-40s are expected the first week of March.
In addition to the Platte River near Fremont, officials are watching the Loup River near Columbus and the Elkhorn River for possible flooding.
Ice jams can cause flooding concerns as snow and ice start to melt.
Observers in eastern Nebraska will be keeping a close eye on area rivers for signs of flooding as a welcome warming trend begins to melt ice and snow.
“We’re just waiting to see how the snow will melt over the next couple of days,” said hydrologist David Pearson of the National Weather Service office in Valley. “We’ll be watching closely.”
Highs on both Monday and Tuesday were expected to be in the mid-40s before dropping back into the upper 30s on Thursday, according to Hallie Bova, a Valley-based weather service meteorologist. The first week of March, Bova said, should see a return to average highs in the mid-40s, warm enough to accelerate the melting of snow and ice.
“How warm it gets kind of depends on how much snow melts,” Bova said. “It does look like we’ll have some more above-normal (temperature) days in early March.”
Pearson said observers will focus on the Platte River near Fremont, where ice jams already have occurred. An ongoing ice jam at Fremont is at the U.S. Highway 77 bridge and continues upstream for 2 to 3 miles, the Papio-Missouri River Natural Resources District reported.
Other locations to watch include the Loup River near Columbus and the Elkhorn River, Pearson said. Current flood advisory details are available at www.weather.gov/omaha.
The ice on the Platte River near Valley measured 15 inches thick on Friday, said Jennifer Stauss Story, a spokeswoman for the Papio-Missouri River NRD. That could signify an increased potential for ice jams, she said.
“We’re a little concerned about the next couple of days,” Pearson said. “If it gets warm enough, that could mean a high (amount) of melt.”
The weather service and other agencies will continue to monitor the river ice conditions and forecasts. Pearson said the hope is always for a slow melt with no — or very little — rain.
“There are no typical years (for ice melting),” Pearson said. “I’ve seen two feet of ice and nothing happened. We had a slow melt. Some years, there’s been very little ice and then flooding.”
