LITTLE ROCK, Ark. — Strong winds toppled power lines and damaged buildings as a line of storms began its slow move through Arkansas.

Heavy rains are also prompting flood warnings throughout the state. Forecasters expect 8 inches or more of rain in some areas of Arkansas through the weekend, and authorities say some roads could become impassable.

The storm system brought damaging winds as it made its way into the state late Tuesday and early Wednesday. The Storm Prediction Center says trees and power lines were knocked down near De Queen in southwest Arkansas. Winds also damaged farm buildings and peeled the roof off a chicken house.

In the opposite corner of the state, utility poles were broken and a grain bin toppled near Pocahontas, about 125 miles (201 kilometers) northeast of Little Rock.
