Some damage has been caused and some people are without power following this morning’s storm.

The National Weather Service issued a hazardous weather outlook at 4:02 a.m for portions of north central Illinois, northwest Illinois, west central Illinois, east central Iowa, northeast Iowa and southeast Iowa. The NWS predicted that thunderstorms with damaging winds were likely this morning with winds of 50 to 70 miles per hour and torrential rainfall.

Clinton Fire Department Battalion Chief Frederick Roling said fire crews were busy this morning after the storm hit Clinton. Beginning at 6:30 a.m., fire crews responded to four calls within a 15- to 30-minute period. Crews responded to reports of lines down at 655 First Ave. and 509 Fifth Ave. North. An alarm was activated at the Evangelical Free Church, 1010 13th Ave. North, but Roling said it was a false alarm.

Fire crews responded to one call at 363 Meadowbrook Drive for a gas leak. Roling said a tree fell, hitting the house and the gas meter, causing the leak. Gas was leaking when firefighters arrived on scene and the crew shut the gas off.

After those four calls, Roling said things settled down. Crews were back in service before 8 a.m.

Alliant Energy Spokesman Ryan Stensland said this morning that 42,000 Alliant Energy customers along the U.S. 30 corridor from Marshalltown to Clinton were without power. He said crews were working to restore power.

The NWS predicted a low threat for strong to severe storms this afternoon and tonight. Today’s weather will be dangerously hot and humid, especially south of Interstate 80, where a heat advisory is in effect. Another round of thunderstorms is possible Tuesday night.
