Scary Hurricane Florence Facts by the Numbers Breaking down the expected impact of this historic storm.

Update: Hurricane Florence made landfall as a Category 1 on Friday and is expected to slowly move over parts of the Carolinas all weekend. In a press conference, North Carolina Gov. Roy Cooper warned, "The storm is going to continue its violent grind across our state for days."

The predictions are not good: massive flooding, destructive winds, life-threatening storm surges and tornadoes are expected as Hurricane Florence heads for the southeast coast of the United States. The storm was downgraded to a category 2 hurricane, but experts are warning -- and pleading with residents in evacuation zones -- to take the situation as deadly serious.

Explaining the difference between a category 3 and category 2 storm, Jeff Byard, an administrator with the Federal Emergency Management Agency, told reporters, "Do you want to get hit with a train or do you want to get hit with a cement truck?"
