July 5 (Reuters) - About 600,000 customers from Ohio to  Virginia remained without power, six days after violent storms  first struck and as a heat wave continues to bake much of the  region, local power companies said Thursday.

The utilities warned that some customers could be without  power - and without air conditioning - for the rest of the week  in the worst-hit areas.

About one-third of customers in West Virginia, the  hardest-hit state in the region, have no power. High  temperatures in Charleston, the capital and largest city, were  expected to reach 95 degrees Fahrenheit (35 Celsius) on Thursday  and top 100 degrees on Friday and Saturday before returning to  near normal levels in the mid 80s by Monday, according to  Accuweather.com.

Folks in West Virginia have already been suffering with   temperatures above 90 degrees and some without air conditioning  since June 28.

The storms crossed the eastern United States with heavy  rain, hail and winds reaching 80 miles per hour (129 kph) last  Friday night, leaving more than 4 million homes and businesses  without power, and the record heat that followed has left at  least 23 people dead.

American Electric Power Co Inc of Ohio said about  224,000 homes and businesses remain without power in West  Virginia and Virginia, and about 144,000 in Ohio.

FirstEnergy Corp of Ohio said it was working to  restore power to more than 111,000 customers in West Virginia  and Maryland. That was down from about the initial 566,000 homes  and businesses affected by the storms.

Illinois-based Exelon Corp said its Baltimore Gas  and Electric unit still had about 53,000 customers out Maryland.

Virginia power company Dominion Resources Inc said it  had about 29,000 customers still without power in its Virginia  and North Carolina service areas.

Washington, D.C.-based Pepco Holdings Inc said it  had about 20,300 customers without power in the District of  Columbia and Maryland, and about 16,100 were out in New Jersey.
