Persistent rain has increased the threat for flooding in the Cedar Valley.

The National Weather Service in Des Moines has issued a flood warning for Black Hawk Creek at Hudson through Thursday morning (Dec. 17, 2015). The main area of concern is from the Black Hawk-Grundy County line to the Cedar River in Waterloo.

Black Hawk Creek is forecast to rise to flood stage late Sunday evening and continue rising to 16.3 feet -- or 2.3 feet above the 14-foot flood stage -- by Monday evening, before cresting.

At 12:45 p.m. Sunday, the water level for Black Hawk Creek at Hudson was at 9.3 feet, which is 4.7 feet below flood stage. No flooding was occurring at that time, but moderate flooding is expected until the level falls below flood stage Thursday morning.

At 15.5 feet, Ranchero Road is under water in the southern part of Waterloo.

According to forecasters, a storm system moving across Iowa has the potential to bring some heavy rainfall amounts with widespread totals around one-to-two-inches by Monday morning. Some locations in the Cedar Valley and other parts of Northeast Iowa had already reported two-inches by Sunday morning from rain that fell overnight.

Showers are expected to continue throughout the overnight hours and end by midday on Monday.
