DES MOINES — Storms that spawned tornadoes have rumbled over much of central and eastern Iowa, toppling trees, cutting power and flooding streets.

The Iowa State Patrol says minor injuries were reported after winds toppled four semitrailer trucks near the Adair rest area along Interstate 80. A 60 mph wind gust was reported at Adair.

Polk County authorities say a lightning strike set fire to a house in Grimes, but the residents got out without injuries.

The weather service says more than 4.5 inches of rain fell on Eagle Grove, and street flooding occurred in several communities.

MidAmerican Energy reports that nearly 4,600 customers remain without power in the Des Moines metropolitan area.
