In Sioux City, nearly 14-hundred customers, many west of Hamilton Boulevard, were without power for a couple of hours Friday evening, ahead of the approaching storm.
A spokesperson with MidAmerican Energy says the outage was caused by a lightning strike that hit some equipment.
Area businesses, like the Casey's General Store on Hamilton Boulevard, were in the dark.
Traffic signals also weren't working after the outage -- and Sioux City Police had to direct traffic.
MidAmerican Energy crews restored power to the affected neighborhoods just after 9 p-m.
Extra crews have been sent to Siouxland because of the forecast.
