Omaha, Nebraska – A Flood Watch remains in effect across parts of eastern Nebraska as warming temperatures trigger ice breakup on area rivers, increasing the risk of ice jams and localized flooding.
According to the National Weather Service in Omaha/Valley, recent mild weather has caused ice to begin breaking up on the Loup River, while increasing the likelihood of ice movement on the Platte and Elkhorn rivers. As a result, the Flood Watch has been extended through Tuesday morning to account for the ongoing threat.
Ice jams occur when large chunks of river ice break free and become lodged downstream, temporarily blocking water flow. This can cause rapid and unpredictable rises in water levels, particularly in low-lying and flood-prone areas. Flooding associated with ice jams can develop quickly, even without additional rainfall.
Areas of concern include communities near Interstate 80, U.S. Highway 30, Highway 275, and U.S. Highway 81, especially around Columbus, Fremont, Norfolk, and areas west and north of Omaha. Portions of the Platte River Valley are particularly vulnerable due to the river’s wide channel and variable ice conditions.
The National Weather Service notes that forecast confidence is medium to high regarding continued ice movement early this week. While not all locations will experience flooding, residents near rivers should be prepared for rapidly changing conditions.
Those living near riverbanks are urged to monitor water levels closely, remain alert for unusual ice movement or sudden rises, and be ready to take action if flooding develops. Emergency officials advise staying clear of river ice, as breakup can occur suddenly and is extremely dangerous.
Commuters and agricultural interests in river-adjacent areas should also be aware of the potential for flooded access roads or impacts to low-water crossings.
The Flood Watch may be adjusted as conditions evolve. Residents are encouraged to follow updates from the National Weather Service and local emergency management officials through Tuesday morning.
