With such low temperatures, it has been strongly advised that everyone affected stays inside. If you absolutely have to go outside, try to keep it short.
When driving, make sure to have an emergency kit set aside in your car filled with a flashlight, batteries, blanket, snacks, water, gloves, boots and be sure to have a full tank of gas.
If using public transportation, keep moving by walking or jumping in place to keep yourself warm when waiting at a train or bus stop.
