The Virginia National Guard has alerted soldiers to go on state active duty to provide assistance after storms ripped through the state, spawning at least one tornado, injuring dozens and killing four people.

The Guard said in a statement that it expects to have more than 50 soldiers on duty early Thursday. Virginia Gov. Terry McAuliffe declared a state of emergency in response to the storm.

Brig. Gen. Paul F. Griffin, director of the Virginia National Guard joint staff, says the initial plan is to provide support for Essex, Richmond, Westmoreland, Sussex and Patrick counties.

Officials say soldiers will work in debris reduction teams. They'll be equipped with chain saws and Humvees to help local emergency responders clear fallen trees and other debris. A rotary wing aviation support will be on standby to provide aerial damage assessment if needed.

Storm systems have brought severe weather to the East Coast and the Midwest.

Tornadoes killed four people and left a path of destruction in Virginia, the hardest-hit state. Virginia State Police spokeswoman Corinne Geller says a 2-year-old child and two men, ages 50 and 26, were killed in the town of Waverly during the storm.

Police say a funnel cloud left an 8- to 10-mile path of destruction in In Appomattox County, Virginia, where one man was killed.

A powerful storm also brought heavy snow and biting winds to the Midwest, leading to mass flight cancellations at Chicago airports and school closings in several states.
