GREENSBORO, N.C. - Clean-up efforts are in full effect following Sunday afternoon's tornado.

Governor Roy Cooper toured the damage with other local officials. At least 20 homes and businesses have been destroyed by the storm.

Three of the cities elementary schools; Hampton Elementary, Peeler Elementary, and Erwin Montessori were damaged so badly that students are being transferred to other schools for the rest of the year.

The Greensboro Parks and Recreation facilities are also having trouble operating after the storm. Several facilities are closed on Tuesday or until power is restored and conditions improve. These include Barber Park, Gateway Gardens, Keeley Park, and Simkins Indoor Sports Pavilion.

Peeler and Windsor community recreation centers are operating on a limited schedule today to support community needs. Also, Bluford and Kings Forest Parks will remain closed indefinitely due to hazardous conditions.

Duke Energy will have 450 additional crew members out working to restore power Tuesday, bringing the total number of crew members to about 950.

The company will also have four "Hot Shot" crews on hand to respond to any emergency situation.

Officials say they re-energized the Kildare substation Monday but didn't see much power come back on, which tells them there's a lot of damage to the infrastructure that will take several days to repair.

As of now, officials know a total of 320 homes and businesses were damaged or destroyed from Sunday's storm that took a four-mile path through eastern Greensboro.

Duke Energy officials say since some of the hardest hit areas are not easily accessible, and the ground is still saturated in some places. Some of the work is going to have to be done by hand.

However, with the extra crews coming in, they hope to have as much power restored as quickly as possible.

"We start at the substation and we begin to work our way out", said Duke Energy District Manager Davis Montgomery. "With every move we make, we want to maximize the number of customers that we can get back on with any single operation that we take. As we do that, we also energize another section of the line and it gives us the opportunity to reroute the poser or to back feed. That may help us as we go further down the line to try to get some of these additional customers back on."

Officials are also saying they're working with Guilford County Schools to identify the school they can get back on the quickest. That way, the district can use it as another substitute school or other staging area for kids.
