July 2 (Reuters) - More than 2.1 million people from Illinois to Virginia remained without power Monday morning after violent storms struck over the weekend, and a heat wave continued to blanket much of the region.
The storms left more than three million homes and businesses without the power needed to run air conditioners during the heat wave, and claimed at least 15 lives, mostly from falling trees and branches across the Midwest and Mid-Atlantic.
