Please make sure that your outside water faucets are properly wrapped to prevent freezing during the low temperatures over the weekend. Townhouses which have outside washer-dryer hookups also need to either heat the room or make sure the pipes are properly insulated.
Make sure that you disconnect any hose attached to the faucet before thermally wrapping them. The water that remains between the hose connection and the actual valve (which is inside the wall) will freeze and fracture the pipe after the valve itself; learned that the hard way.
Home Depot, Lowes and other home stores sell foam faucet covers fairly cheap, like $3 each.
