A watch has been issued for the Platte, Elkhorn, and Loup rivers due to potential ice jam development. This heightened threat is due to persistent warm weather. Those with interests along area rivers, especially in low-lying areas, should remain vigilant to the potential for rapidly rising water.

* WHAT...Flooding caused by an ice jam is possible.

* WHERE...Portions of east central, northeast, and southeast Nebraska, including the following counties, in east central Nebraska, Butler, Dodge, Douglas, Sarpy, Saunders and Washington. In northeast Nebraska, Antelope, Colfax, Cuming, Madison, Pierce, Platte and Stanton. In southeast Nebraska, Cass.

* WHEN...Through Monday evening.

* IMPACTS...The formation of an ice jam could result in sudden rises of water, leading to a rapid flooding situation. Ice jams can cause water level fluctuations of 1 to 3 feet over a very short time period and without much notice.

* ADDITIONAL DETAILS... - While no ice movement has been observed or reported, several consecutive days of highs ranging from the upper 40s to mid 60s suggest breakup and movement is imminent.
