A major storm has drenched the Northeast and slammed it with fierce winds, knocking out power to hundreds of thousands. That's followed a bout of violent weather ranging from snowstorms to tornado reports in other areas of the country. Parts of Long Island in New York were inundated by coastal flooding on Wednesday. In New Jersey, roads were flooded and rivers were rising. The same weather system already brought heavy rain, hail and at least three reported tornadoes to the South. Meanwhile, many areas of Florida face the threat of flooding. And the snowy Midwest is being warned that temperatures could plunge.
