Violent storms that battered the eastern U.S. are being blamed for killing at least 10 people and leaving more than 3 million without power.

At least six people were killed in Virginia; two in New Jersey; one in Maryland; and one in Ohio. Widespread power outages were reported in Washington, Virginia, Maryland, West Virginia, New Jersey and Ohio.

Many are facing the possibility of temperatures near or above 100 degrees without electricity — and without air conditioning.

In addition to the heat, officials say cell phone coverage is spotty. Many residents were asked to conserve water because sewage stations had been without power for a time. And authorities cautioned people to drive carefully because tree limbs littered roads and hundreds of traffic signals were out.
