Each year, flooding kills an average of 60 people in the United States. In 2011, 18 people died due to flash flooding in Arkansas.
The NWS released the statistics as part of its Flood Safety Awareness Week. Statistics show flooding kills more people each year that tornadoes or lightning.
Here's an in-depth breakdown of flooding deaths in Arkansas last year:
