Hurricane Florence is barreling towards the US east coast with powerful sustained winds of up to 105 mph. According to Business Insider, the hurricane is predicted to bring up to 40 inches of rain and 13 feet of storm surge to the coastal area. The National Hurricane Center, which called these levels "catastrophic," has created a tool to help people visualize what that could mean. Once the water reaches two or three feet, cars will begin to float. Flooding of six feet or more is life-threatening. At nine feet of storm surge flooding, the only way to survive is to move up to a higher level until rescuers arrive by boat.
