(AP) — Thousands of customers are still without power following a thunderstorm that caused widespread damage in the Omaha area.

Omaha Public Power District said Tuesday morning that more than 10,600 of its Douglas County customers didn’t have electricity. That’s down considerably from the outage’s peak of 52,000 late Monday morning.

OPPD workers were being helped by crews from other utilities, including the Nebraska Public Power District.

Winds reaching 70 mph knocked down trees and limbs, damaging vehicles, homes, businesses and other a variety of buildings on Monday before the storm blew into Iowa.

National Weather Service forecasters are keeping an eye on a storm system that’s moving toward Omaha with winds that could reach 50 mph.
