Some residents in Richmond may be without water on Monday after a major winter storm knocked out power to the Virginia city's water reservoir system, causing it to malfunction.

The outage comes after a major winter storm caused widespread impacts across more than a dozen states, including hundreds of thousands of power outages across the Midwest and Mid-Atlantic.

The city of Richmond, in partnership with the Virginia Department of Health, issued an immediate boil water advisory on Monday, urging all residents to conserve water and boil it before consumption until further notice.
