What Americans should stock up on to prepare for massive winter storm

Americans are being urged to prepare as a massive winter storm is expected to stretch more than 2,000 miles across the U.S. this weekend, potentially affecting more than 235 million people in over 40 states. The storm is forecast to bring heavy snow, sleet and freezing rain beginning Friday and lasting through Monday, raising concerns about widespread power outages, dangerous travel conditions and prolonged disruptions, according to National Weather Service Director Ken Graham."Prepare now," Graham told FOX Weather Thursday. "If you think about power outages, you think about the cold, you need to be prepared to have what you need for a week."

I just beg everybody, please use them correctly," Graham said. "We lose a lot of people due to improper use of generators. … Keep them far away from the house. They're fine to use, but use them properly because it could be dangerous if you don't."The National Weather Service also recommends people keep a winter survival kit in a vehicle. That kit should include a phone and charger, blankets, flashlights, a first-aid kit, nonperishable food, extra clothing, cat litter or sand for traction, a shovel, ice scraper and brush, waterproof matches, a basic tool kit and paper maps.GOOGLE, PARTNERS LAUNCH SATELLITES INTO SPACE TO DETECT FIRES A cardboard box is filled with nonperishable canned goods.
