The Cedar Valley and the rest of Northeast Iowa remain under an enhanced threat of severe weather following an early round of damaging thunderstorms this morning (Monday, June 22, 2015).

A line of severe storms moved across the area, prompting the National Weather Service (NWS) to issue severe thunderstorm warnings for a number of counties. In some parts of Northeast Iowa, the storm dumped two inches of rain in about 30 minutes. The heavy rainfall produced some localized street flooding, which impacted multiple roads in Independence and reportedly closed U-S Highway 63 in Waterloo for a time.

The heavy rainfall is causing some flood concerns in parts of the area. In Floyd County, the National Weather Service has issues a flood warning for the Cedar River at Charles City through late Wednesday night.

NWS officials predict the river will rapidly rise above flood stage Tuesday morning. At 8:30 a.m. Monday, the river stage at Charles City was 4.4 feet. Flood stage is 12.0 feet. Minor flooding is expected.

Across there area, officials have received multiple reports of trees and power lines down. In Butler County, emergency management officials said there are intermittent trees down from Allison to Aplington. Similar reports have been received from other areas of Butler and Chickasaw counties, as well as parts of Waterloo, Cedar Falls and Evansdale.

In Waterloo, officials at Lost Island Water Park said is closed today due to storm damage.

Outside Waterloo, building damage was reported in multiple locations. Officials in Buchanan County said the storm destroyed a structure near Hazleton and some barns on the Buchanan-Delaware county line. The National Weather Service said sustained winds in Independence were clocked at 94 mph.

In Fayette County, the storm reportedly twisted a house off its foundation near Maynard.

Utility are working to restoring electricity to nearly 11,000 homes and businesses across Iowa. At 9:15 a.m., Mid-American Energy reported more than 9,200 people were without power in Waterloo, and other parts of the Cedar Valley. Crews are working to restore electricity to nearly 1,100 customers in Elk Run Heights and a portion of Evansdale.

At 10 a.m., Alliant Energy reported about 13,500 customers without power state-wide. The majority of the effected customers -- nearly 9,500 -- were in Bremer, Buchanan and Fayette counties and other parts of the company's east region.

The line of thunderstorms moved into Eastern Iowa just before 8 a.m. As the intense weather system rolled across the area, the National Weather Service issued a severe thunderstorm warning for Black Hawk, Bremer, Butler, Franklin, Grundy, Hardin and Grundy counties. Buchanan County was added a short time later.
