People in Arkansas are trying to cope with an ice storm that knocked out power to nearly 500,000 homes and businesses across the southern plains. Many of the homes have no heat.

The airport in Little Rock cancelled flights for a third day and the state government is shut down.

Thick ice lies on the ground and on tree limbs that are in danger of crashing.

At least 10 car accidents have been blamed on the storm. Some communities, such as the city of Hot Springs, have no water and the National Guard has been called in to help.

The state's power company says that restoring service may take up to a week.

The U.S. weather service predicts the icy conditions will subside by Thursday, but more snow is expected in many areas.
