Clean-up is underway in Waterloo, Waverly and other parts of northeast Iowa following  a night of severe weather, which spawned at least 12 confirmed tornadoes.

Officials with the National Weather Service said they were sending out survey teams to the hardest hit areas on Thursday. One crew was being sent to Bremer and Butler counties, and another was going to Calhoun and Hamilton counties in western Iowa.

Some of the most significant damage was reported near Shell Rock, Waverly, Oelwein and Manchester. Tornadoes were sighted near each of those cities. The twisters either destroyed or damaged property, uprooted trees and downed power lines. No injuries were reported.

National Weather Service officials said late Wednesday a trained spotter reported that a tornado briefly touched down near the John Deere Foundry on Westfield Ave. in Waterloo. The apparent twister caused some minor damage on both sides of U.S. Highway 218.

On Thursday, officials in Waterloo were offering residents guidance for storm damage clean-up in neighborhoods affected by the severe storm. Officials said crews from the city's Forestry and Public Works Department were working to clear streets in an area generally north of University Avenue and east of Greenhill Road, including the Cedar River Park, former Edison School and Gates Park neighborhoods.

Waterloo residents were being asked to take debris from damaged private trees to the city's Compost/Yard Waste Site at 2749 Independence Ave. The facility is open daily from 8 AM to 8 PM.

Wednesday night's storm knocked down trees and utility lines around the Cedar Valley, leaving more than 2,700 Mid-American Energy customers without power in Waterloo and Evansdale. Company officials reported at least 1,600 outages in Waterloo and just over 1,100 in Evansdale.

Statewide, more than 30 tornado warnings were issued Wednesday afternoon and evening. The National Weather Service damage survey teams were expected to release preliminary results and conclusions of their findings Thursday afternoon.
