Power lines snapped by 99 mph winds in Marshalltown are shown here on South Sixth Street near the American Legion.

A state of civil emergency has been declared in Marshalltown after the 99-mile-per-hour storm roared through. People are asked to stay home to allow first responders to do their job.

Marshalltown Police Chief Mike Tupper said he has received more than 40 gas leaks reports. If there is a leak or the scent of gas is present, evacuate as soon as possible and call 911.

Scott Reigstad, a spokesperson for Alliant, said the company has 225,000 outages in Iowa due to the storm. Roughly 13,000 Marshalltown smart meters are reporting no power. He does not know, at this time, when power will be restored.

“We are assessing the damage,” Reigstad said. “There are a lot of transmission poles and lines down . . . in multiple cities.”

All Alliant employees have been called in. Reigstad said it is a all-hands on deck situation.

He asked for people to stay away from downed lines.

“Please assume they are energized,” Reigstad said. “Stay away from the poles. Don’t try to do anything with them.”

People can call 1-800-ALLIANT to broken lines and poles.

“We ask everybody to be safe and patient,” Reigstad said. “Our crews are out. There is a lot of damage. It will be a while for power to return.”

He said updates will be provided on the Alliant Facebook and Twitter pages.
